NRF Log stops working after softdevice enabled

[Mihir Chauhan]

Hi,

I am working on BLE project which has 2 custom services with characteristics values having properties as READ/WRITE and NOTIFY.

Now when I enabled NRF_LOG through UART. RTT logging is disabled in my case.

But after soft device initialization logging stops working.

Please suggest how I can debug into this error ?

I have attached my SDK_Config file which I am using for my project.sdk_config.h

Hi,

Does the application work ok apart from logging? E.g, can you connect to it with BLE? And gave you tried other BLE examples such as ble_app_hrs and confirmed that logging work with those?

My logs are working before soft device initialization. But after BLE stack initialized successfully NRF log is not working.

Also I have tries with app_hrs example but in there also my logs are not working. I have used pin 6 and 8 for UART TX/RX. In my code logging is working just before ble stack initialization.

My BLE functionality is working perfectly fine, BLE connect. READ/WRITE through nordic mobile app is also working as expected.

I can't think of anything the Softdevice could to do interfere with logging. Have you tried to do logging over RTT to see if that works? Also, are you testing this on a nRF52 DK or a custom board?
