Problem with flashing to sparkfun nRF52832 using nRF52 DK for BLE_UART code?

vishal

Hello sir, I have develop my BLE_UART code is working fine with nRF52832 DK board but when i flash into spark fun nRF52 is not working. But i able to flash into Spark fun other code like BLE_APPS_hrs, led blinking and other also. Why i am not able to flash BLE_UART example or my own develop code into spark-fun board. I am using eclipse IDE is it any need to do setting in eclipse IDE for create correct hex file. because my code hex file size is 93KB.

Thnaks......

    Do you have this line in your uart_init()

    .flow_control = APP_UART_FLOW_CONTROL_ENABLED,

    If so, try to disable it lie this

    .flow_control = APP_UART_FLOW_CONTROL_DISABLED,

    then test in PCA10040 to make sure the ble_uart code is still working (try a low baud like 57600), then flash it into the sparkfun breakout board and test.

    As for the sparkfun breakout pin mapping for the uart tx and rx you need to consult the sparkfun experts; I believe they have a forum for those kind of questions?
