NRF51822's ble_app_uart_c project problem

I have tried ble_app_uart_c project in SDk 9 , SDK 10 or SDK11 , but they have the same problem.

Problem is that slave(SDk 9,ble_app_uart) can send data to master(by terminal) , but master can't.

I did not modify the code that download form official website.

I remember that they can communicate each other before , so i confuse it.

Thanks.

  • You need to put ble_app_uart (the one you uploaded) on one of the nrf51 board (peripheral), and the ble_app_uart_c on the other nrf51 board(central). Then with both terminals on you should be able to write on one and it should appear on the other, and vice versa.

    If you are trying to connect via a phone, you should only be able to see the peripheral and only connect to it, because the phone is a central device.
