Thingy:91 & Debug Out over USB

[morerook]

Hello, I want to know how I can print console messages out over the COM ports that the Thingy:91 exposes using the nRF Connect SDK. I'm able to see the com ports but I'm unable to see any debug printouts.

Hi,

The USB port on the Thingy:91 is connected to the nRF52840 SoC. In order to print serial messages from the nRF9160, the Connectivity bridge application must be flashed to the nRF52840 SoC. UART0 and UART1 on the nRF9160 is connected to UART0 and UART1 on the nRF52840.

 

Best regards,

Bendik

Ok, I've built and flashed the Connectivity Bridge application to the nRF52840. But I'm still not able to get any debug messages from the nRF9160 on the Thingy:91, whether I connect to either of the COM ports that appear.

On the nRF9160 only the non-secure code have access to UART0 and UART1. So to make sure you are using thingy91_nrf9160_ns as the build target.
