Hi:
I user pca10056.
I tested light_bulb,light_coordinator and light_switch.Only light_coordinator uart has output.
Test conditions:
baudrate 1000000.
Tx P0.06.
#define ZIGBEE_TRACE_LEVEL 4
What terminal program are you using ?
Do you see the log if you set NRF_LOG_DEFERRED to 0 in sdk_config.h ?
Do you see the log if you press the "IF BOOT/RESET" button on the DK?
Have you made any changes to the project that could have caused this issue ? If yes, could you download a clean copy of the Zigbee SDK?
Thank you for your support.
