Add UART to ble_app_hrs_rscs_relay

[Avi]

I would like to add UART as an option to the "ble_app_hrs_rscs_relay" example in SDK16, But keep the peripheral low power. 

  i.e. once I set a GPIO, the UART will start to work and enable communication with the device (in order to dump the flash content)

Can you please guide me how to do it?

Have you attempted to start merging ble_app_hrs_rscs_relay example with uart library and driver first? I think that would be the first thing to do. I do not think that there is any easy way to do it apart from just starting to merge them and attach the problems as they come. I know that this suggestion is of not much help, but we, unfortunately, do not have any example to share.
