nRF Developer Academy BLE Fundamentals l4_e3 Not Working

[icfarrar0]

Hello,

I am a beginner when working with nRF. I am trying to run the l4_e3 solution code, but it doesn't seem to work. I can connect via BLE, but nothing is being shown on the terminal via UART. I am using an nRF52840-DK to program a EV-BC840.

Hi,

Have you connected to the UART pins on the device and configured the pins properly? (If you were testing on a DK this would work out of the box as the onboard debugger acts as a USB-UART bridge, but not for external boards). If not, you can use RTT logging instead of UART to observe the logs.

This is how I have it set up, except the nRF52DK is a nRF52840DK instead as recommended at the bottom of that picture. I have code that just outputs to RTT, but it stops outputting to the terminal the moment I add CONFIG_BT=y to the prj.conf file.

I see. Can you share your projec build folder, or at least the generated .config? It would be intereting to see if RTT logging is actually enabled in the build, or if it has been disabled for some reason.
