Hi,
First some info on the used setup:
Host <-spi-> RCP
RCP is nrf52840 with ot-nrf528xx (rev 063233b) built for ot-rcp without any source code changes
Host is NXP imx soc running zephyrOS (latest main) with changes for openthread host support
Now my problem:
In all cases, I can join a thread network, the dataset is received, and a connected router device has my device in the neighbor table (both for thread 1.1 and 1.2).
If I build both Host and RCP for thread 1.1 everything works, but if I build both for thread 1.2, I am unable to send coap messages, ping other devices, ...
I do receive messages however.
I can see messages being sent to the RCP while debugging over SPI when a transmit is requested, but that is as far as can trace now.
Are there configuration options that I am missing to make thread 1.2 work? Is it something related to the radio driver? Any help would be appreciated.
Thanks,
Pieter
