THE uart of 52832

[jinxiuqueling73]

When I used  "nRF5_SDK_15.0.0_a53641a\examples\ble_central\ble_app_uart_c " ,  it run ok .    But my hareware  is used  PIN33 for RX,  PIN32 for TX. So I  changed  pca10040.h ,please see the following .  And now the software doesn't  run. The J-LINK shows  "  0> <error> app: Communication error occurred while handling UART. ".

WHY? please help me. thank you.  My board is uesd 52832.

#define RX_PIN_NUMBER 19  / /8
#define TX_PIN_NUMBER 18  //6

nRF52832 has 32 GPIOs from P0.00 to P0.31. Check your hardware for the right pin numbers.

I said the pin nuber is the  number  of IC.

[jinxiuqueling73]

RX IS used P0.19 , TX is used P0.18

[Bastien Reynard]

Then,

#define RX_PIN_NUMBER 19
#define TX_PIN_NUMBER 18

No?

[jinxiuqueling73]

#define RX_PIN_NUMBER 19 //8
#define TX_PIN_NUMBER 18//6
#define CTS_PIN_NUMBER 0XFF
#define RTS_PIN_NUMBER 0XFF
#define HWFC false// true

I changed as above. but the software still doesnot run.
