RE: Adding an 2nd UART to the BLE UART example

BBI — Thu, 10 Aug 2023 08:16:54 GMT

Thank you, the code works now. I tested that the BLE still is able to connect and forward data over the UART, which still works fine. Hopefully this will be able to help someone else as well.

RE: Adding an 2nd UART to the BLE UART example

Not at my end.
I had to add nrfx_ppi.c and nrfx_timer.c to the project to make it compile.

I see that after running your code on the board, there is an assert in nrfx_timer.c:72 where the code checks that you are not using NRF_TIMER0 for initializing the UARTE.

So in the main.c:702, changing the NRF_LIBUARTE_ASYNC_DEFINE to use TIMER2 instead of TIMER0 and enabling TIMER2_ENABLED and NRFX_TIMER2_ENABLED in sdk_config.h fixes the assert in your code.

I have rebuilt the same code and it compiles with 0 errors and 5 warnings. These warnings are from variables not being used, which are test variables I put into the code.

I will retry porting/merging the code, so that it is in its simplest form.

I am not able to compile your code to be able check why it resets. Combing two samples is time consuming process in terms of finding out what configs and resources you need to enable and disable.
