Problems on nrf52840 coap server to receive packages

[taoyinzhou]

Hi All, 

I want to implement a function to send data from the internet coap client to nrf52840 DK coap server. The nrf52840 runs .hex file which is one modified from Nordic Thread SDK example\thread\simple_coap_server, but I find that whether I use the otCoapAddResource registered function or the coap_default_handler function, neither received the coap data that internet coap client sent. I've caught coap message on the wpan0 interface of OTBR, but the function didn't work as if it hadn't received those package, that is the OTBR in wpan0 has received this package, but it doesn't deliver to nrf52840 DK coap sever. 

Therefore, how do I get the nrf52840 DK coap server to receive and process packages from coap client successfully?

I really appreciate any help you can provide. 

Best, 

Tao

I tried to set the Log level to 4 as you said, and then checked with debug in SEGGER Embedded Studio, but I only saw the print Added by myself, without any other log.

Yes, logs from OpenThread are set to OT_LOG_LEVEL_CRIT by default. If you want to increase this level, you can do that as described in the link I provided above. Then you need to rebuild the OpenThread libraries.
