I'm using put all together 2 sample
a) NUS Uart that is used for the configuration;
b) zephyr/samples/net/opentread/coap Using the nrf5340dk/nrf5340/cpuapp.
The compilation work well but whei i do the download I will have this error:
[00:00:01.412,719] <err> spinel_ipc_backend: IPC endpoint bind ti+-----------------------------+
