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

Hello Tom,

  Are you testing this on a nRF52DK?

  Have you checked with a logic analyser or a scope that there is indeed the correct data on the Tx and Rx lines?

  Are you getting any error codes?

  The only thing that you have change on the example is the pins?

Hi Martin,

              Yes,I use nRF52DK to test.

The errro code is 0x0000004.

the Tx and Rx lines is correct.

Yes, the only thing that I changed on the example is the pin number in pca10040.h

#define RX_PIN_NUMBER 12 //12 //8
#define TX_PIN_NUMBER 11 //11 //6
