    • 115200 baud rate

    • 8 data bits

Running the demo

The demo does not require user interaction.
The application will automatically start scanning and will connect to the first advertiser who is advertising the Current Time Service.
If the connection is successful, the application performs service discovery to find the characteristics of the Current Time Service. If discovery is successful, the application will subscribe to receive time notifications from the peer.
The application will display the received notifications in the console.
