 Since nRF Toolbox version 1.16.0 the UART profile supports also Android Wear devices (watches).

 The wearable application may work in 2 modes: as a remote control of the phone, or directly connected to a UART device.
 
 1. Connect your phone to the UART device. After few seconds you should get a notification on the watch that your device is now connected. Swipe it left to see Disconnect button (will send a message to the phone to terminate the connection with UART target) and Open button. Click the Open button to see a list of your UART configurations. Click one and see the list of active buttons. When pressed the button will send a message to the phone using Google Play Services and the phone will send the command to the target device. In this mode you may have more than one watch connected to the phone and use both as remote controls.
