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.
RX IS used P0.19 , TX is used P0.18
#define RX_PIN_NUMBER 19#define TX_PIN_NUMBER 18
