I found out that the problem was the TX_PIN that i changed form 6 to 9. For some reason the pin9 don't work. I'll go through the datasheet to find the reason.

Thanks for the support

Thanks for the reply.

I tried right now and the error was NRF_ERROR_NO_MEM.

I'm trying to fix it acutally but i'm not finding the correct value for the macro placement.

Any help would be appreciated.

Thanks for the help

NRF_BREAKPOINT_COND is probably due to an error check being hit (or a hard fault). You should define DEBUG for your project (just select the Debug build configuration from the dropdown if you are using SES) and enable logging. Then you will probably see from the log what went wrong.

For your reference, the implementation for the error handler is in app_error_wak.c (and the hardfault implementation is in hardfault_implementation.c).

Hi,

Thanks for the answer, i tried right now.

The code is not working. It end at "NRF_BREAKPOINT_CND" and seems that the error is given from the "uarte_irq_handler" function.

I've tried it on 3 different board

Thanks for the support

Have you looked at the UART example in the SDK ?
