Hello! I have been playing with this example and got some LEDs blink here and there, but would very much like to have UART working as well. The documentation states that "UART logging can be used instead of the LEDs." and I was wondering if this refers to the files in "...\SDK\nRF51_SDK_10.0.0_dc26b5e\examples\ble_central\ble_app_multilink_central\pca10028" and if it was possible to get a more detailed example on how to get this to work?
