Capability THREAD_JOINER (required for "Joiner:State") is not supported by NCP (14) with wpantund

[AllieSargente]

Hello, I was reading through the OpenThread Commissioning Guide (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thread_commissioning.html) Attempting to use the NCP Firmware, everything was working fine until step 4 -- Adding the Joiner, when I attempted to run the code "joiner --join N0RDIC" in wpanctl, it errored out, after some probing by running "joiner -s" I was given the following message:

Joiner:State: Capability THREAD_JOINER (required for "Joiner:State") is not supported by NCP (14)
Error 14 (0x0E)

I'm using mainline wpantund (I compiled it yesterday from https://github.com/openthread/wpantund) and the precompiled NCP firmware found here: (https://openthread.io/platforms/co-processor/firmware#download_nrf52840_firmware_image)

Any help would be appreciated.

Hi,

The pre-build hex file of the NCP firmware you are running doesn't have the JOINER=1 flag so it doesn't support the Joiner role, so there is no joiner state to report.

The NCP sample in NCS use the pre-build master library, so it includes the joiner flag. If you build the NCP example in NCS then joiner should work, see:
