ble_app_uart example changed UART pin failed

[liujirong888]

Hi expert,

         I use the example below:

D:\Nordic\nRF51 SDK\nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ble_app_uart

I changed UART pin from default pin0.08 and pin 0.06 to pin 0.12 and pin 0.11,

the receive function is OK,but send out function is failed.

when I use Termite3.2 to send data will make the board reset.

Would you tell me why?

Regards

Tom

• What function is giving you 0x04?

Define "DEBUG" in the preprocessor defines, turn off optimization, set a breakpoint at line 73 in "app_error.c", and run a debug session to find out what "APP_ERROR_CHECK" returns. (more)

 I have tested this on my side with the same pin numbers and it works.

Hi Martin,

          I set breakpoint at line " while (loop);" in function "app_error_save_and_stop" in app_error.c ,

I captured the picture for your reference.the error code is 0x000004.

I also followed you instruction to set a breakpoint at line 73 in app_erroc.c 

 Line73:   app_error_fault_handler(NRF_FAULT_ID_SDK_ERROR, 0, (uint32_t)(&error_info));

app_error_fault_handler return code 0x2413C.

          

  By the way I use a external uart to USB device to connect with pin 0.12 and pin 0.11.
