-# MeshCore KISS Modem Protocol
-
-Standard KISS TNC firmware for MeshCore LoRa radios. Compatible with any KISS client (Direwolf, APRSdroid, YAAC, etc.) for sending and receiving raw packets. MeshCore-specific extensions (cryptography, radio configuration, telemetry) are available through the standard SetHardware (0x06) command.
-
-## Serial Configuration
-
-115200 baud, 8N1, no flow control.
-
-## Frame Format
-
-Standard KISS framing per the KA9Q/K3MC specification.
-
-| Byte | Name | Description |
-|------|------|-------------|
-| `0xC0` | FEND | Frame delimiter |
-| `0xDB` | FESC | Escape character |
-| `0xDC` | TFEND | Escaped FEND (FESC + TFEND = 0xC0) |
-| `0xDD` | TFESC | Escaped FESC (FESC + TFESC = 0xDB) |
-
-```
-┌──────┬───────────┬──────────────┬──────┐
-│ FEND │ Type Byte │ Data (escaped)│ FEND │
-│ 0xC0 │  1 byte   │ 0-510 bytes  │ 0xC0 │
-└──────┴───────────┴──────────────┴──────┘
-```
-
-### Type Byte
-
-The type byte is split into two nibbles:
-
-| Bits | Field | Description |
-|------|-------|-------------|
-| 7-4 | Port | Port number (0 for single-port TNC) |
-| 3-0 | Command | Command number |
-
-Maximum unescaped frame size: 512 bytes.
-
-## Standard KISS Commands
-
-### Host to TNC
-
-| Command | Value | Data | Description |
-|---------|-------|------|-------------|
-| Data | `0x00` | Raw packet | Queue packet for transmission |
-| TXDELAY | `0x01` | Delay (1 byte) | Transmitter keyup delay in 10ms units (default: 50 = 500ms) |
-| Persistence | `0x02` | P (1 byte) | CSMA persistence parameter 0-255 (default: 63) |
-| SlotTime | `0x03` | Interval (1 byte) | CSMA slot interval in 10ms units (default: 10 = 100ms) |
-| TXtail | `0x04` | Delay (1 byte) | Post-TX hold time in 10ms units (default: 0) |
-| FullDuplex | `0x05` | Mode (1 byte) | 0 = half duplex, nonzero = full duplex (default: 0) |
-| SetHardware | `0x06` | Sub-command + data | MeshCore extensions (see below) |
-| Return | `0xFF` | - | Exit KISS mode (no-op) |
-
-### TNC to Host
-
-| Type | Value | Data | Description |
-|------|-------|------|-------------|
-| Data | `0x00` | Raw packet | Received packet from radio |
-
-Data frames carry raw packet data only, with no metadata prepended. The Data command payload is limited to 255 bytes to match the MeshCore maximum transmission unit (MAX_TRANS_UNIT); frames larger than 255 bytes are silently dropped. The KISS specification recommends at least 1024 bytes for general-purpose TNCs; this modem is intended for MeshCore packets only, whose protocol MTU is 255 bytes.
-
-### CSMA Behavior
-
-The TNC implements p-persistent CSMA for half-duplex operation:
-
-1. When a packet is queued, monitor carrier detect
-2. When the channel clears, generate a random value 0-255
-3. If the value is less than or equal to P (Persistence), wait TXDELAY then transmit
-4. Otherwise, wait SlotTime and repeat from step 1
-
-In full-duplex mode, CSMA is bypassed and packets transmit after TXDELAY.
-
-## SetHardware Extensions (0x06)
-
-MeshCore-specific functionality uses the standard KISS SetHardware command. The first byte of SetHardware data is a sub-command. Standard KISS clients ignore these frames.
-
-### Frame Format
-
-```
-┌──────┬──────┬─────────────┬──────────────┬──────┐
-│ FEND │ 0x06 │ Sub-command  │ Data (escaped)│ FEND │
-│ 0xC0 │      │   1 byte    │   variable   │ 0xC0 │
-└──────┴──────┴─────────────┴──────────────┴──────┘

-**TxDone (0xF8)**: Sent after a packet has been transmitted. Contains a single byte: 0x01 for success, 0x00 for failure.
-
-**RxMeta (0xF9)**: Sent immediately after each standard data frame (type 0x00) with metadata for the received packet. Contains SNR (1 byte, signed, value x4 for 0.25 dB precision) followed by RSSI (1 byte, signed, dBm). Enabled by default; can be toggled with SetSignalReport. Standard KISS clients ignore this frame.

-- All multi-byte values are little-endian unless stated otherwise
-- SNR values in RxMeta are multiplied by 4 for 0.25 dB precision
-- TxDone is sent as a SetHardware event after each transmission
-- Standard KISS clients receive only type 0x00 data frames and can safely ignore all SetHardware (0x06) frames

-# nRF52 Power Management
-
-## Overview
-
-The nRF52 Power Management module provides battery protection features to prevent over-discharge, minimise likelihood of brownout and flash corruption conditions existing, and enable safe voltage-based recovery.
-
-## Features
-
-### Boot Voltage Protection
-- Checks battery voltage immediately after boot and before mesh operations commence
-- If voltage is below a configurable threshold (e.g., 3300mV), the device configures voltage wake (LPCOMP + VBUS) and enters protective shutdown (SYSTEMOFF)
-- Prevents boot loops when battery is critically low
-- Skipped when external power (USB VBUS) is detected
-
-### Voltage Wake (LPCOMP + VBUS)
-- Configures the nRF52's Low Power Comparator (LPCOMP) before entering SYSTEMOFF
-- Enables USB VBUS detection so external power can wake the device
-- Device automatically wakes when battery voltage rises above recovery threshold or when VBUS is detected
-
-### Early Boot Register Capture
-- Captures RESETREAS (reset reason) and GPREGRET2 (shutdown reason) before SystemInit() clears them
-- Allows firmware to determine why it booted (cold boot, watchdog, LPCOMP wake, etc.)
-- Allows firmware to determine why it last shut down (user request, low voltage, boot protection)
-
-### Shutdown Reason Tracking
-Shutdown reason codes (stored in GPREGRET2):
-| Code | Name | Description |
-|------|------|-------------|
-| 0x00 | NONE | Normal boot / no previous shutdown |
-| 0x4C | LOW_VOLTAGE | Runtime low voltage threshold reached |
-| 0x55 | USER | User requested powerOff() |
-| 0x42 | BOOT_PROTECT | Boot voltage protection triggered |
-
-## Supported Boards

-
-Notes:
-- "Implemented" reflects Phase 1 (boot lockout + shutdown reason capture).
-- User power-off on Heltec T114 does not enable LPCOMP wake.
-- VBUS detection is used to skip boot lockout on external power, and VBUS wake is configured alongside LPCOMP when supported hardware exposes VBUS to the nRF52.
-
-## Technical Details
-
-### Architecture
-
-The power management functionality is integrated into the `NRF52Board` base class in `src/helpers/NRF52Board.cpp`. Board variants provide hardware-specific configuration via a `PowerMgtConfig` struct and override `initiateShutdown(uint8_t reason)` to perform board-specific power-down work and conditionally enable voltage wake (LPCOMP + VBUS).
-
-### Early Boot Capture
-
-A static constructor with priority 101 in `NRF52Board.cpp` captures the RESETREAS and GPREGRET2 registers before:
-- SystemInit() (priority 102) - which clears RESETREAS
-- Static C++ constructors (default priority 65535)
-
-This ensures we capture the true reset reason before any initialisation code runs.
-
-### Board Implementation
-
-To enable power management on a board variant:
-
-1. **Enable in platformio.ini**:
-   ```ini
-   -D NRF52_POWER_MANAGEMENT
-   ```
-
-2. **Define configuration in variant.h**:
-   ```c
-   #define PWRMGT_VOLTAGE_BOOTLOCK    3300   // Won't boot below this voltage (mV)
-   #define PWRMGT_LPCOMP_AIN          7      // AIN channel for voltage sensing
-   #define PWRMGT_LPCOMP_REFSEL       2      // REFSEL (0-6=1/8..7/8, 7=ARef, 8-15=1/16..15/16)
-   ```
-
-3. **Implement in board .cpp file**:
-   ```cpp
-   #ifdef NRF52_POWER_MANAGEMENT
-   const PowerMgtConfig power_config = {
-     .lpcomp_ain_channel = PWRMGT_LPCOMP_AIN,
-     .lpcomp_refsel = PWRMGT_LPCOMP_REFSEL,
-     .voltage_bootlock = PWRMGT_VOLTAGE_BOOTLOCK
-   };
-
-   void MyBoard::initiateShutdown(uint8_t reason) {
-     // Board-specific shutdown preparation (e.g., disable peripherals)
-     bool enable_lpcomp = (reason == SHUTDOWN_REASON_LOW_VOLTAGE ||
-                           reason == SHUTDOWN_REASON_BOOT_PROTECT);
-
-     if (enable_lpcomp) {
-       configureVoltageWake(power_config.lpcomp_ain_channel, power_config.lpcomp_refsel);
-     }
-
-     enterSystemOff(reason);
-   }
-   #endif
-
-   void MyBoard::begin() {
-     NRF52Board::begin();  // or NRF52BoardDCDC::begin()
-     // ... board setup ...
-
-   #ifdef NRF52_POWER_MANAGEMENT
-     checkBootVoltage(&power_config);
-   #endif
-   }
-   ```
-
-   For user-initiated shutdowns, `powerOff()` remains board-specific. Power management only arms LPCOMP for automated shutdown reasons (boot protection/low voltage).
-
-4. **Declare override in board .h file**:
-   ```cpp
-   #ifdef NRF52_POWER_MANAGEMENT
-     void initiateShutdown(uint8_t reason) override;
-   #endif
-   ```
-
-### Voltage Wake Configuration
-
-The LPCOMP (Low Power Comparator) is configured to:
-- Monitor the specified AIN channel (0-7 corresponding to P0.02-P0.05, P0.28-P0.31)
-- Compare against VDD fraction reference (REFSEL: 0-6=1/8..7/8, 7=ARef, 8-15=1/16..15/16)
-- Detect UP events (voltage rising above threshold)
-- Use 50mV hysteresis for noise immunity
-- Wake the device from SYSTEMOFF when triggered
-
-VBUS wake is enabled via the POWER peripheral USBDETECTED event whenever `configureVoltageWake()` is used. This requires USB VBUS to be routed to the nRF52 (typical on nRF52840 boards with native USB).
-
-**LPCOMP Reference Selection (PWRMGT_LPCOMP_REFSEL)**:
-| REFSEL | Fraction | VBAT @ 1M/1M divider (VDD=3.0-3.3) | VBAT @ 1.5M/1M divider (VDD=3.0-3.3) |
-|--------|----------|------------------------------------|--------------------------------------|
-| 0 | 1/8 | 0.75-0.82 V | 0.94-1.03 V |
-| 1 | 2/8 | 1.50-1.65 V | 1.88-2.06 V |
-| 2 | 3/8 | 2.25-2.47 V | 2.81-3.09 V |
-| 3 | 4/8 | 3.00-3.30 V | 3.75-4.12 V |
-| 4 | 5/8 | 3.75-4.12 V | 4.69-5.16 V |
-| 5 | 6/8 | 4.50-4.95 V | 5.62-6.19 V |
-| 6 | 7/8 | 5.25-5.77 V | 6.56-7.22 V |
-| 7 | ARef | - | - |
-| 8 | 1/16 | 0.38-0.41 V | 0.47-0.52 V |
-| 9 | 3/16 | 1.12-1.24 V | 1.41-1.55 V |
-| 10 | 5/16 | 1.88-2.06 V | 2.34-2.58 V |
-| 11 | 7/16 | 2.62-2.89 V | 3.28-3.61 V |
-| 12 | 9/16 | 3.38-3.71 V | 4.22-4.64 V |
-| 13 | 11/16 | 4.12-4.54 V | 5.16-5.67 V |
-| 14 | 13/16 | 4.88-5.36 V | 6.09-6.70 V |
-| 15 | 15/16 | 5.62-6.19 V | 7.03-7.73 V |
-
-**Important**: For boards with a voltage divider on the battery sense pin, LPCOMP measures the divided voltage. Use:
-`VBAT_threshold ≈ (VDD * fraction) * divider_scale`, where `divider_scale = (Rtop + Rbottom) / Rbottom` (e.g., 2.0 for 1M/1M, 2.5 for 1.5M/1M, 3.0 for XIAO).
-
-### SoftDevice Compatibility
-
-The power management code checks whether SoftDevice is enabled and uses the appropriate API:
-- When SD enabled: `sd_power_*` functions
-- When SD disabled: Direct register access (NRF_POWER->*)
-
-This ensures compatibility regardless of BLE stack state.
-
-## CLI Commands
-
-Power management status can be queried via the CLI:
-
-| Command | Description |
-|---------|-------------|
-| `get pwrmgt.support` | Returns "supported" or "unsupported" |
-| `get pwrmgt.source` | Returns current power source - "battery" or "external" (5V/USB power) |
-| `get pwrmgt.bootreason` | Returns reset and shutdown reason strings |
-| `get pwrmgt.bootmv` | Returns boot voltage in millivolts |
-
-On boards without power management enabled, all commands except `get pwrmgt.support` return:
-```
-ERROR: Power management not supported
-```
-
-## Debug Output
-
-When `MESH_DEBUG=1` is enabled, the power management module outputs:
-```
-DEBUG: PWRMGT: Reset = Wake from LPCOMP (0x20000); Shutdown = Low Voltage (0x4C)
-DEBUG: PWRMGT: Boot voltage = 3450 mV (threshold = 3300 mV)
-DEBUG: PWRMGT: LPCOMP wake configured (AIN7, ref=3/8 VDD)
-```
-
-## Phase 2 (Planned)
-
-- Runtime voltage monitoring
-- Voltage state machine (Normal -> Warning -> Critical -> Shutdown)
-- Configurable thresholds
-- Load shedding callbacks for power reduction
-- Deep sleep integration
-- Scheduled wake-up
-- Extended sleep with periodic monitoring

+- **TX Characteristic** (Client → Device): `0000ff02-0000-1000-8000-00805f9b34fb`
 
 ### Connection Steps
 
 1. **Scan for Devices**
-    - Scan for BLE devices advertising the MeshCore Service UUID
-    - Optionally filter by device name (typically contains "MeshCore" prefix)
-    - Note the device MAC address for reconnection
+   - Scan for BLE devices advertising the MeshCore service UUID
+   - Filter by device name (typically contains "MeshCore" or similar)
+   - Note the device MAC address for reconnection
 
 2. **Connect to GATT**
-    - Connect to the device using the discovered MAC address
-    - Wait for connection to be established
+   - Connect to the device using the discovered MAC address
+   - Wait for connection to be established
 
 3. **Discover Services and Characteristics**
-    - Discover the service with UUID `6E400001-B5A3-F393-E0A9-E50E24DCCA9E`
-    - Discover the RX characteristic `6E400002-B5A3-F393-E0A9-E50E24DCCA9E`
-        - Your app writes to this, the firmware reads from this
-    - Discover the TX characteristic `6E400003-B5A3-F393-E0A9-E50E24DCCA9E`
-        - The firmware writes to this, your app reads from this
+   - Discover the service with UUID `0000ff00-0000-1000-8000-00805f9b34fb`
+   - Discover RX characteristic (`0000ff01-...`) for receiving data
+   - Discover TX characteristic (`0000ff02-...`) for sending commands
 
 4. **Enable Notifications**
-    - Subscribe to notifications on the TX characteristic to receive data from the firmware
+   - Subscribe to notifications on the RX characteristic
+   - Enable notifications/indications to receive data from the device
+   - On some platforms, you may need to write to a descriptor (e.g., `0x2902`) with value `0x01` or `0x02`
 
-5. **Send Initial Commands**
-    - Send `CMD_APP_START` to identify your app to firmware and get radio settings
-    - Send `CMD_DEVICE_QEURY` to fetch device info and negotiate supported protocol versions
-    - Send `CMD_SET_DEVICE_TIME` to set the firmware clock
-    - Send `CMD_GET_CONTACTS` to fetch all contacts
-    - Send `CMD_GET_CHANNEL` multiple times to fetch all channel slots
-    - Send `CMD_SYNC_NEXT_MESSAGE` to fetch the next message stored in firmware
-    - Setup listeners for push codes, such as `PUSH_CODE_MSG_WAITING` or `PUSH_CODE_ADVERT`
-    - See [Commands](#commands) section for information on other commands
+5. **Send AppStart Command**
+   - Send the app start command (see [Commands](#commands)) to initialize communication
+   - Wait for OK response before sending other commands
+
+### Connection State Management
+
+- **Disconnected**: No connection established
+- **Connecting**: Connection attempt in progress
+- **Connected**: GATT connection established, ready for commands
+- **Error**: Connection failed or lost
 
 **Note**: MeshCore devices may disconnect after periods of inactivity. Implement auto-reconnect logic with exponential backoff.
 
 ### BLE Write Type
 
-When writing commands to the RX characteristic, specify the write type:
+When writing commands to the TX characteristic, specify the write type:
 
 - **Write with Response** (default): Waits for acknowledgment from device
 - **Write without Response**: Faster but no acknowledgment
 
 **Platform-specific**:
-
 - **Android**: Use `BluetoothGattCharacteristic.WRITE_TYPE_DEFAULT` or `WRITE_TYPE_NO_RESPONSE`
 - **iOS**: Use `CBCharacteristicWriteType.withResponse` or `.withoutResponse`
 - **Python (bleak)**: Use `write_gatt_char()` with `response=True` or `False`
 
-**Recommendation**: Use write with response for reliability.
+**Recommendation**: Use write with response for reliability, especially for critical commands like `SET_CHANNEL`.
 
 ### MTU (Maximum Transmission Unit)
 
 The default BLE MTU is 23 bytes (20 bytes payload). For larger commands like `SET_CHANNEL` (66 bytes), you may need to:
 
 1. **Request Larger MTU**: Request MTU of 512 bytes if supported
-    - Android: `gatt.requestMtu(512)`
-    - iOS: `peripheral.maximumWriteValueLength(for:)`
-    - Python (bleak): MTU is negotiated automatically
+   - Android: `gatt.requestMtu(512)`
+   - iOS: `peripheral.maximumWriteValueLength(for:)`
+   - Python (bleak): MTU is negotiated automatically
 
-### Command Sequencing
+2. **Handle Chunking**: If MTU is small, commands may be split automatically by the BLE stack
+   - Ensure all chunks are sent before waiting for response
+   - Responses may also arrive in chunks - buffer until complete
+
+### Command Sequencing and Timing
 
 **Critical**: Commands must be sent in the correct sequence:
 
 1. **After Connection**:
-    - Wait for BLE connection to be established
-    - Wait for services/characteristics to be discovered
-    - Wait for notifications to be enabled
-    - Now you can safely send commands to the firmware
+   - Wait for GATT connection established
+   - Wait for services/characteristics discovered
+   - Wait for notifications enabled (descriptor write complete)
+   - **Wait 200-1000ms** for device to be ready (some devices need initialization time)
+   - Send `APP_START` command
+   - **Wait for `PACKET_OK` response** before sending any other commands
 
 2. **Command-Response Matching**:
-    - Send one command at a time
-    - Wait for a response before sending another command
-    - Use a timeout (typically 5 seconds)
-    - Match response to command by type (e.g: `CMD_GET_CHANNEL` → `RESP_CODE_CHANNEL_INFO`)
+   - Send one command at a time
+   - Wait for response before sending next command
+   - Use timeout (typically 5 seconds)
+   - Match response to command by:
+     - Command type (e.g., `GET_CHANNEL` → `PACKET_CHANNEL_INFO`)
+     - Sequence number (if implemented)
+     - First-in-first-out queue
+
+3. **Timing Considerations**:
+   - Minimum delay between commands: 50-100ms
+   - After `APP_START`: Wait 200-500ms before next command
+   - After `SET_CHANNEL`: Wait 500-1000ms for channel to be created
+   - After enabling notifications: Wait 200ms before sending commands
+
+**Example Flow**:
+```python
+# 1. Connect and discover
+await connect_to_device(device)
+await discover_services()
+await enable_notifications()
+await asyncio.sleep(0.2)  # Wait for device ready
+
+# 2. Send AppStart
+send_command(build_app_start())
+response = await wait_for_response(PACKET_OK, timeout=5.0)
+if response.type != PACKET_OK:
+    raise Exception("AppStart failed")
+
+# 3. Now safe to send other commands
+await asyncio.sleep(0.1)  # Small delay between commands
+send_command(build_device_query())
+response = await wait_for_response(PACKET_DEVICE_INFO, timeout=5.0)
+```
 
 ### Command Queue Management
 
-For reliable operation, implement a command queue.
+For reliable operation, implement a command queue:
 
-**Queue Structure**:
+1. **Queue Structure**:
+   - Maintain a queue of pending commands
+   - Track which command is currently waiting for response
+   - Only send next command after receiving response or timeout
 
-- Maintain a queue of pending commands
-- Track which command is currently waiting for a response
-- Only send next command after receiving response or timeout
+2. **Implementation**:
+```python
+class CommandQueue:
+    def __init__(self):
+        self.queue = []
+        self.waiting_for_response = False
+        self.current_command = None
+    
+    async def send_command(self, command, expected_response_type, timeout=5.0):
+        if self.waiting_for_response:
+            # Queue the command
+            self.queue.append((command, expected_response_type, timeout))
+            return
+        
+        self.waiting_for_response = True
+        self.current_command = (command, expected_response_type, timeout)
+        
+        # Send command
+        await write_to_tx_characteristic(command)
+        
+        # Wait for response
+        response = await wait_for_response(expected_response_type, timeout)
+        
+        self.waiting_for_response = False
+        self.current_command = None
+        
+        # Process next queued command
+        if self.queue:
+            next_cmd, next_type, next_timeout = self.queue.pop(0)
+            await self.send_command(next_cmd, next_type, next_timeout)
+        
+        return response
+```
 
-**Error Handling**:
-
-- On timeout, clear current command, process next in queue
-- On error, log error, clear current command, process next
+3. **Error Handling**:
+   - On timeout: Clear current command, process next in queue
+   - On error: Log error, clear current command, process next
+   - Don't block queue on single command failure

-## Packet Structure
+## Protocol Overview
 
 The MeshCore protocol uses a binary format with the following structure:
 
-- **Commands**: Sent from app to firmware via RX characteristic
-- **Responses**: Received from firmware via TX characteristic notifications
-- **All multi-byte integers**: Little-endian byte order (except CayenneLPP which is Big-endian)
+- **Commands**: Sent from client to device via TX characteristic
+- **Responses**: Received from device via RX characteristic (notifications)
+- **All multi-byte integers**: Little-endian byte order
 - **All strings**: UTF-8 encoding

 ### Channel Types
 
-1. **Public Channel**
-    - Uses a publicly known 16-byte key: `8b3387e9c5cdea6ac9e5edbaa115cd72`
-    - Anyone can join this channel, messages should be considered public
-    - Used as the default public group chat
-2. **Hashtag Channels**
-    - Uses a secret key derived from the channel name
-    - It is the first 16 bytes of `sha256("#test")`
-    - For example hashtag channel `#test` has the key: `9cd8fcf22a47333b591d96a2b848b73f`
-    - Used as a topic based public group chat, separate from the default public channel
-3. **Private Channels**
-    - Uses a randomly generated 16-byte secret key
-    - Messages should be considered private between those that know the secret
-    - Users should keep the key secret, and only share with those you want to communicate with
-    - Used as a secure private group chat
+1. **Public Channels** (Index 0)
+   - No secret required
+   - Anyone with the channel name can join
+   - Use for open communication
+
+2. **Private Channels** (Indices 1-7)
+   - Require a 16-byte secret
+   - Secret is expanded to 32 bytes using SHA-512 (see [Secret Generation](#secret-generation))
+   - Only devices with the secret can access the channel
 
 ### Channel Lifecycle
 
-1. **Set Channel**:
-    - Fetch all channel slots, and find one with empty name and all-zero secret
-    - Generate or provide a 16-byte secret

+
+### Channel Index Management
+
+- **Index 0**: Reserved for public channels
+- **Indices 1-7**: Available for private channels
+- If a channel exists at index 0 but should be private, migrate it to index 1-7
+
+---
+
+## Secret Generation and QR Codes
+
+### Secret Generation
+
+For private channels, generate a cryptographically secure 16-byte secret:
+
+**Pseudocode**:
+```python
+import secrets
+
+# Generate 16 random bytes
+secret_bytes = secrets.token_bytes(16)
+
+# Convert to hex string for storage/sharing
+secret_hex = secret_bytes.hex()  # 32 hex characters
+```
+
+**Important**: Use a cryptographically secure random number generator (CSPRNG). Do not use predictable values.
+
+### Secret Expansion
+
+When sending the secret to the device via `SET_CHANNEL`, the 16-byte secret must be expanded to 32 bytes:
+
+**Process**:
+1. Take the 16-byte secret
+2. Compute SHA-512 hash: `hash = SHA-512(secret)`
+3. Use the first 32 bytes of the hash as the secret field in the command
+
+**Pseudocode**:
+```python
+import hashlib
+
+secret_16_bytes = ...  # Your 16-byte secret
+sha512_hash = hashlib.sha512(secret_16_bytes).digest()  # 64 bytes
+secret_32_bytes = sha512_hash[:32]  # First 32 bytes
+```
+
+This matches MeshCore's ED25519 key expansion method.
+
+### QR Code Format
+
+QR codes for sharing channel secrets use the following format:
+
+**URL Scheme**:
+```
+meshcore://channel/add?name=<ChannelName>&secret=<32HexChars>
+```
+
+**Parameters**:
+- `name`: Channel name (URL-encoded if needed)
+- `secret`: 32-character hexadecimal representation of the 16-byte secret
+
+**Example** (using example secret - NOT a real secret):
+```
+meshcore://channel/add?name=YourChannelName&secret=9b647d242d6e1c5883fde0c5cf5c4c5e
+```
+
+**Alternative Formats** (for backward compatibility):
+
+1. **JSON Format**:
+```json
+{
+  "name": "YourChannelName",
+  "secret": "9b647d242d6e1c5883fde0c5cf5c4c5e"
+}
+```
+*Note: The secret value above is an example only - generate your own secure random secret.*
+
+2. **Plain Hex** (32 hex characters):
+```
+9b647d242d6e1c5883fde0c5cf5c4c5e
+```
+*Note: This is an example hex value - always generate your own cryptographically secure random secret.*
+
+### QR Code Generation
+
+**Steps**:
+1. Generate or use existing 16-byte secret
+2. Convert to 32-character hex string (lowercase)
+3. URL-encode the channel name
+4. Construct the `meshcore://` URL
+5. Generate QR code from the URL string
+
+**Example** (Python with `qrcode` library):
+```python
+import qrcode
+from urllib.parse import quote
+import secrets
+
+channel_name = "YourChannelName"
+# Generate a real cryptographically secure secret (NOT the example value)
+secret_bytes = secrets.token_bytes(16)
+secret_hex = secret_bytes.hex()  # This will be a different value each time
+
+# Example value shown in documentation: "9b647d242d6e1c5883fde0c5cf5c4c5e"
+# DO NOT use the example value - always generate your own!
+
+url = f"meshcore://channel/add?name={quote(channel_name)}&secret={secret_hex}"
+qr = qrcode.QRCode(version=1, box_size=10, border=5)
+qr.add_data(url)
+qr.make(fit=True)
+img = qr.make_image(fill_color="black", back_color="white")
+img.save("channel_qr.png")
+```
+
+### QR Code Scanning
+
+When scanning a QR code:
+
+1. **Parse URL Format**:
+   - Extract `name` and `secret` query parameters
+   - Validate secret is 32 hex characters
+
+2. **Parse JSON Format**:
+   - Parse JSON object
+   - Extract `name` and `secret` fields
+
+3. **Parse Plain Hex**:
+   - Extract only hex characters (0-9, a-f, A-F)
+   - Validate length is 32 characters
+   - Convert to lowercase
+
+4. **Validate Secret**:
+   - Must be exactly 32 hex characters (16 bytes)
+   - Convert hex string to bytes
+
+5. **Create Channel**:
+   - Use extracted name and secret
+   - Send `SET_CHANNEL` command

+
+## Platform-Specific Notes
+
+### Android
+- Use `BluetoothGatt` API
+- Request `BLUETOOTH_CONNECT` and `BLUETOOTH_SCAN` permissions (Android 12+)
+- Enable notifications by writing to descriptor `0x2902` with value `0x01` or `0x02`
+
+### iOS
+- Use `CoreBluetooth` framework
+- Implement `CBPeripheralDelegate` for notifications
+- Request Bluetooth permissions in Info.plist
+
+### Python
+- Use `bleak` library for cross-platform BLE support
+- Handle async/await for BLE operations
+- Use `asyncio` for command-response patterns
+
+### JavaScript/Node.js
+- Use `noble` or `@abandonware/noble` for BLE
+- Handle callbacks or promises for async operations
+- Use `Buffer` for binary data manipulation
 
 ---
 
 ## Troubleshooting
 
 ### Connection Issues
-
 - **Device not found**: Ensure device is powered on and advertising
 - **Connection timeout**: Check Bluetooth permissions and device proximity
 - **GATT errors**: Ensure proper service/characteristic discovery
 
 ### Command Issues
-
 - **No response**: Verify notifications are enabled, check connection state
-- **Error responses**: Verify command format and check error code
-- **Timeout**: Increase timeout value or try again
+- **Error responses**: Verify command format, check channel index validity
+- **Timeout**: Increase timeout value or check device responsiveness
 
 ### Message Issues
-
 - **Messages not received**: Poll `GET_MESSAGE` command periodically
-- **Duplicate messages**: Implement message deduplication using timestamp/content as a unique id
-- **Message truncation**: Send long messages as separate shorter messages
+- **Duplicate messages**: Implement message deduplication using timestamps/hashes
+- **Message truncation**: Split long messages into chunks
+
+### Secret/Channel Issues
+- **Secret not working**: Verify secret expansion (SHA-512) is correct
+- **Channel not found**: Query channels after connection to discover existing channels
+- **Channel index 0**: Migrate to index 1-7 for private channels
