Hi,

I recommend that you take a look at the UART example in the SDK. You can find the source code and the project file of the example in the following folder: <SDK_InstallFolder>\examples\peripheral\uart.

You can download the SDK 12.3 here.

HI, we have tried everything that you said and we try to send AT command through mobile but did not get any response from EC25. As you said earlier about "You can then later modify the uart_event_handle() function, so that you send AT commands to the ec25 automatically, based on what the ec25 is sending to the nRF51" could you please send me the changes that i have to make in my code to send AT command.
