I'm happy to hear that you got it working now! I was just about to look at your case again.

Thans for confirming that the firmware is operating correctly. Next, I suggest ensuring that the nRF52832 chip on the nRF52 DK is not running any firmware that might interfere with the UART communication since it is connected to the same pins. This can be achieved by erasing the chip.

yes the custom board is able to run. The client can connect to it through ble and get sensor data. I just couldn't see any uart info out of it.

Hi,

Are you able to debug the firmware running on your board to verify that it starts up? The first thing I would try is to verify whether the program reaches main(). It may be failing before the logger is started.

Best regards,
