This application enables the mobile phone to connect with the embedded device (micro controller) via Bluetooth, helping you to complete the wireless control of the control system, parameter adjustment, data curve feedback and so on.
1.Professional mode
The data packet is sent and received based on a simple protocol. The variables of the packet are linked to the widgets for manual manipulation and status feedback. The app supports a variety of widgets such as buttons, switches, drag bars, joysticks, energy bars, and more.The most important thing is that you can customize almost everything according to your needs.
2.Command mode
You can send data to and receive data from the classic Bluetooth module.
3.Button mode
Custom buttons give you the freedom to edit the data sent to the device when the button is pressed or released.

Note: The operation of the professional mode is somewhat complicated, but it is very powerful. I hope that you can patiently explore it.
