Test of Ziggurat with OpenThread RCP on Nordic Semiconductor (Nordic Semi) hardware?

[Hedda]

It should also be possible to get OpenThread RCP working on Nordic NRF528xx and . Like for example Nordic Semiconductor nRF52840 SoC, Nordic Semiconductor nRF52833 SoC and Nordic Semiconductor nRF52811 SoC.

• https://github.com/openthread/ot-nrf528xx

Anyone willing and able to build and experiment some more? Please share your findings here!

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

Apparently earlier experimentation by puddly from more than 1-year ago pointed at that to transmission issues (reception appears fine) when using STREAM_RAW mode with Nordic Semiconductor (Nordic Semi. See previous discussions here:

• Test of OpenThread RCP on Nordic hardware Nerivec/zigbee-on-host#18

Note to anyone wanting to test this, 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 (otbr-rcp) firmware corretly 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.

Example from ot-nrf52xxx git repo has not working properly for me, and i think development of rcp firmware for nrf mcu has move to zephyr project and downstream to latest nrf connect sdk, which you could access from vscode extension "nrf connect". i have tried and successfully compile and run with instruction from this instruction on nrf connect docs. since toolchain are installed from vscode extension, then you have to open terminal from nrf connect. And if you have board with adafruit bootloader in it, you could use uf2conv.py from microsoft/uf2 to convert build hex file to get uf2 you can load to your board. i can confirm binary build from nrf connect can run on nrf52 board i have here.
