The recommended Android App is Bluetooth Electronics available free on the Play Store.

The following properties of the controller has to be set up for proper functioning:

  1. Forward Button:

    • Press: "f"
    • Release: "F"
  2. Backward Button:

    • Press: "b"
    • Release: "B"
  3. Left Button:

    • Press: "l"
    • Release: "L"
  4. Right Button:

    • Press: "r"
    • Release: "R"
  5. Object Detection Trigger Button:

    • Press: "o"
    • Release: ""
  6. Wall Follower Trigger Button:

    • Press: "w"
    • Release: ""
  7. Speed Control Slider:

    • Min: 0
    • Max: 255
    • On Change: "" + value + "A"
