When starting the app, go to connect bluetooth, the bluetooth symbol icon located in the right corner of the screen.
It will open the available devices with FFE1 characteristics.
After the devices appear, click on it and the connection will occur.
After the connection is successful, simply activate the desired functions.
We have the functions.
-On/Off where we send a command to the hardware to turn on.
-Chromotherapy- Where we choose a color on the screen that opens, and send a command to hw.
-Power- sends a power command to hw.
-Turbo- sends turbo command to hw.
-Dynamics-sends dynamics command to hw.
-Bilateral-We have the arrows above the image, which sends a selection command to hw.
Involved in these commands we have the business rule, where some commands only function with the power on.
All commands only work with Bluetooth connected.
