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.

I have the ble_app_uart_c and ble_app_uart on two nrf51DK and they work, I can send both ways. And the only thing I changed was the baudrate. but it should work for you if you set the same baudrate on the terminal.

Why do you think it doesn't work for you?

Hi,

It can work, but i only can see the data that sending from salve in terminal.

that is, I can't see the data that sending from master in terminal.

By the way ,I changed the baudrate , tx and rx pins.

Thanks.

Where are you putting the central and peripheral? on 2 nrf51/52 boards?

Are both connected to the pc? If so, you need to open two terminals with the COMs where the boards are connected and see the prints there.

one thing is not to change the tx and rx pins on the configuration if you are using the usb cable to the pc. let the pins be as they were on the example. You uploaded the peripheral side, it seems to be ok, at least here works, but I'm using my own libraries so you could have changed something on yours.

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.
