-## 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:

-
-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.  
-- 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
+**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.
 
-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.

+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:

-- Coding Rate (CR): 5  
-- Bandwidth (BW): 250.00  
 
-(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.)

+
+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)

+# 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`.
