NRF51822's ble_app_uart_c project problem

[where]

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.

Hi,

I put the project on 2 nrf51 boards, and open two terminals with COMs.

The result is that i only can see the data that sending from salve in terminal.

I download the SDK10 that from official Web 10 minute ago, and flash the ble_app_uart that i update it.

Amazing thing that I only can not see the data from phone in terminal occur.

I thing it is the same problem.

By the way , if i copy the SDK9 ble_app_uart project's nus_data_handler() and uart_event_handle() in SDK10, it is the same problem.

thanks.
