Yes, though you may need to power cycle the board also, since the chip may be in debug mode. Are you using any other peripherals here? You may need to stop those also in between transmissions.

Try this:

   // Hardware uart can be disabled to save power and extend battery life
   app_uart_close();

Thanks for this insight, so then when I turn off the UART I should see a decrease in current consumption which for some reason I am not seeing.

Hi,

There is no problem to use the BLE NUS service for any data you may wish to send and receive. The example have been by default setup to take data from the UART peripheral, hence the name BLE NUS. You can safely disable the NRF_UART0 if you don't need it for other purposes. Typically the UART peripheral will draw high current, but the BLE NUS service don't use any current other than when the application actively call ble_nus_data_send() to send data, but that current is the same for all BLE services.

Best regards,
Kenneth
