Have you ever thought this scene: Open phone, I can see the current barometric pressure or motion acceleration. the Xadow module can help you achieve this.
For this demo, you need to use the
Xadow Main Board
Xadow BLE Slave
If you have learned to achieve Demo 1 and Demo 2, you just need to connect the Xadow Main Board, Xadow OLED, Xadow Accelerometer and Xadow BLE Slave modules and download the code:BLE_Slave.
Now you can open BLE_Slave INO file, compile and upload.
You can see there are two commands(ledon and ledoff) in the phone screen. They are used to control the GREEN indicator state. Have a try!
