+### 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
-    - Send `CMD_SET_CHANNEL` with name and secret
-2. **Get Channel**:
-    - Send `CMD_GET_CHANNEL` with channel index
-    - Parse `RESP_CODE_CHANNEL_INFO` response
+1. **Create Channel**:
+   - Choose an available index (1-7 for private channels)
+   - Generate or provide a 16-byte secret
+   - Send `SET_CHANNEL` command with name and secret
+   - **Store the secret locally** (device does not return it)
+
+2. **Query Channel**:
+   - Send `GET_CHANNEL` command with channel index
+   - Parse `PACKET_CHANNEL_INFO` response
+   - Note: Secret will be null in response (security feature)
+
 3. **Delete Channel**:
-    - Send `CMD_SET_CHANNEL` with empty name and all-zero secret
-    - Or overwrite with a new channel
+   - Send `SET_CHANNEL` command with empty name and all-zero secret
+   - Or overwrite with a new channel
+
+### 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

 3. **Message Handling**:
-   - Send `CMD_SYNC_NEXT_MESSAGE` when `PUSH_CODE_MSG_WAITING` is received
-   - Implement message deduplication to avoid display the same message twice

+
+## 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

+# Maintenance Tools
+
+This directory contains automation for managing our **Friendly Fork**. It allows us to integrate community-submitted Pull Requests from the upstream repository into our local development branches.
+
+## Why this exists
+
+In firmware development, critical bug fixes or hardware support often exist in the upstream "Pull Request" queue long before they are officially merged. This tool allows us to build an integrated firmware version that includes those necessary patches while remaining syncable with the official source.
+
+## Usage
+
+### 1. Prerequisites
+
+You must have the original repository added as a remote named `upstream`:
+
+```bash
+git remote add upstream https://github.com/meshcore-dev/MeshCore.git
+```
+
+### 2. Basic Commands
+
+**Apply specific patches:**
+To pull in PR #1338 and PR #1400 from the upstream project:
+
+```bash
+./tools/maint/apply_patches.sh 1338 1400
+
+```
+
+**Start over (Reset):**
+To wipe the integrated branch and reset it to match the official upstream `main` branch exactly:
+
+```bash
+./tools/maint/apply_patches.sh --reset
+
+```
+
+## Traceability
+
+Every time this script runs, it updates `patch_manifest.log`. This file tracks:
+
+* The date of the integration.
+* The base commit SHA we started from.
+* The specific commit SHA of every PR applied.
+
+**This log is essential for debugging firmware regressions.** If the hardware fails, check the manifest to identify which experimental patch might be the cause.
+
+---
+
+### A Note on Merge Conflicts
+
+If a PR cannot be applied automatically, the script will abort the merge. You will need to:
+
+1. Manually merge the PR.
+2. Resolve the conflicts in your editor.
+3. Commit the result.
+4. Manually update the `patch_manifest.log`.
