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.

Does the EC25 send something to the nRF51 when it starts up? Is your settings correct? I.e. baud-rate, flow-control, parity, pin numbers is correct? Do you have access to a logic analyzer/scope, so you can see the data sent over the UART lines?
