Test of OpenThread RCP on Nordic hardware

[Nerivec]

Anyone willing and able to build and experiment some more, please share your findings here!

Example from OpenThread: https://github.com/openthread/ot-nrf528xx

Current reported state:

• Early experimentation from puddly points to transmission issues (reception appears fine) when using STREAM_RAW mode with Nordic firmware/hardware.

Known issues:

Known limitations:

Can not build fw for my NRF52840 (Nice! Nano v2.0) :(

Anyone tested this more, I understand that it should be compatible with Nordic Semi USB adapters and development boards/kits based on nRF52 series or nRF53 series SoCs as long as build the OpenThread RCP firmware corretcly for each specific board/kit to get pin-compatibility.

Like example:

• nRF52840 dongle
• nRF52840 development kit
• nRF5340 development kit (nRF5340 DK has not been tested but should be compatible)
• nRF54L15 DK (nRF54L Series Development Kit)

also probably these less expensive USB dongles and open-source hardware;

• nRF52840 MDK USB Dongle = Open-Source hardware from makerdiary.
• Holyiot 21017 (model HOLYIOT-21017-nRF52840) = nRF52840 USB dongle with PA (Power Amplifier) and external antenna.
• Holyiot 22046 (Model: YJ-17120-USB or HOLYIOT-22046-USB) = Black or white mini nRF52840 USB dongle with PCB antenna.
• Ebyte E104-BT5040U USB dongle = an inexpensive nRF52840 based USB radio dongle from Ebyte.
• Seeed Studio XIAO nRF54L USB-C development boards based on nRF54L15 chip.

I try to flash otbr-rcp compiled by apalrd but still can't get it to working, it stop led blinking after being flashed. Is bootloader matter for rcp example to run correctly ? i have adafruit nrf52 bootloader installed on it

i have explored a bit on supermicro board with nrf52 soc and it only run if i specified openthread older commit in it. Also setting up cca default mode from ED only to ED and CS and setting ED threshold can give you better stability on noisy environment (by comparing z2m maps, where coordinator arrow pointing outside to other router, 1 vs 2)
