 ## RAK Wireless Board Support in PlatformIO
 Before building/flashing the RAK4631 targets in this project, there is, unfortunately, some patching you have to do to your platformIO packages to make it work. There is a guide here on the process:
   [RAK Wireless: How to Perform Installation of Board Support Package in PlatformIO](https://learn.rakwireless.com/hc/en-us/articles/26687276346775-How-To-Perform-Installation-of-Board-Support-Package-in-PlatformIO)
 After building, you will need to convert the output firmware.hex file into a .uf2 file you can copy over to your RAK4631 device (after doing a full erase) by using the command `uf2conv.py -f 0xADA52840 -c firmware.hex` with the python script available from:

 ### 2.3. Q: What frequencies are supported by MeshCore?
-**A:** It supports the 868MHz range in the UK/EU and the 915MHz range in New Zealand, Australia, and the USA. Countries and regions in these two frequency ranges are also supported. The firmware and client allow users to set their preferred frequency.  
+**A:** It supports the 868MHz range in the UK/EU and the 915MHz range in New Zealand, Australia, and the USA. Countries and regions in these two frequency ranges are also supported.
 - Australia and New Zealand are on **915.8MHz**
 - UK and EU are on **869.525MHz**
 - Canada and USA are on **910.525MHz**
 - For other regions and countries, please check your local LoRa frequency
-In UK and EU, 867.5MHz is not allowed to use 250kHz bandwidth and it only allows 2.5% duty cycle for clients.  869.525Mhz allows an airtime of 10%, 250KHz bandwidth, and a higher EIRP, therefore MeshCore nodes can send more often and with more power. That is why this frequency is chosen for UK and EU.  This is also why Meshtastic also uses this frequency.  
+Use the smartphone client or the repeater setup feature on there web flasher to set your radios' RF settings by choosing the preset for your regions.
-[Source](https://discord.com/channels/826570251612323860/1330643963501351004/1356540643853209641)
+Recently, as of October 2025, many regions have moved to the "narrow" setting, aka using BW62.5 and a lower SF number (instead of the original SF11).  For example, USA/Canada (Recommended) preset is 910.525MHz, SF7, BW62.5, CR5.
 After extensive testing, many regions have switched or about to switch over to BW62.5 and SF7, 8, or 9.  Narrower bandwidth setting and lower SF setting allow MeshCore's radio signals to fit between interference in the ISM band, provide for a lower noise floor, better SNR, and faster transmissions.
 If you have consensus from your community in your region to update your region's preset recommendation, please post your update request on  the [#meshcore-app](https://discord.com/channels/1343693475589263471/1391681655911088241) channel on the [MeshCore Discord server ](https://discord.gg/cYtQNYCCRK) to let Liam Cottle know.
 the rest of the radio settings are the same for all frequencies:  
 - Spread Factor (SF): 11  
 - Coding Rate (CR): 5

 (Originally MeshCore started with SF 10.  recently (as of late April 2025) the community has advocated SF 11 also a viable option for longer range but a little slower transmission. Currently there are MeshCore meshes with SF 10 and SF 11.  Liam Cottle's smartphone app's presets now recommend SF 10 for Australia and SF 11 for all other regions and countries.  EU and UK has SF 10 and SF 11 presets.  Work with your local meshers on deciding with SF number is best for your use cases.  In the future, there may be bridge nodes that can bridge SF 10 and SF 11 (or even different frequencies) traffic.)

 ### 3.7. Q: My repeater maybe suffering from deafness due to high power interference near my mesh's frequency, it is not hearing other in-range MeshCore radios.  what can I do?
 **A:** This may be due to the SX1262 radio's auto gain control feature.  You can use this command to preiodically reset its AGC.  
 `set agc.reset.interval <number>`
 The `<number>` unit is in seconds and is incremented by 4.  `set agc.reset.interval 4` works well to cure deafness.  
 This is a very low cost operation.  AGC reset is done by simply setting `state = STATE_IDLE;` in function `RadioLibWrapper::resetAGC()` in `RadioLibWrappers.cpp`

 TL;DR: default CR to 5 for good stable links.  If it is not a solid link and is intermittent, change to CR to 7 or 8.
 Forward Error Correction is a process of adding redundant bits to the data to be transmitted. During the transmission, data may get corrupted by interference (changes from 0 to 1 / 1 to 0). These error correction bits are used at the receivers for restoring corrupted bits.
 The Code Rate of a forward error correction expresses the proportion of bits in a data stream that actually carry useful information.
 There are 4 code rates used in LoRaWAN:
 4/5
 4/6
 5/7
 4/8
 For example, if the code rate is 5/7, for every 5 bits of useful information, the coder generates a total of 7 bits of data, of which 2 bits are redundant.
 Making the bandwidth 2x wider (from BW125 to BW250) allows you to send 2x more bytes in the same time. Making the spreading factor 1 step lower (from SF10 to SF9) allows you to send 2x more bytes in the same time.
 Lowering the spreading factor makes it more difficult for the gateway to receive a transmission, as it will be more sensitive to noise. You could compare this to two people taking in a noisy place (a bar for example). If you’re far from each other, you have to talk slow (SF10), but if you’re close, you can talk faster (SF7)

 # 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 │
 └──────┴──────┴─────────────┴──────────────┴──────┘

 ### Unsolicited Events
 The TNC sends these SetHardware frames without a preceding request:
 **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.

 ## Notes
 - Data payload limit (255 bytes) matches MeshCore MAX_TRANS_UNIT; no change needed for KISS “1024+ recommended” (that applies to general TNCs, not MeshCore)
 - Modem generates identity on first boot (stored in flash)
 - 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
 - See [packet_structure.md](./packet_structure.md) for packet format
