We have developed an APP for Android users that simplifies the control of the OSOYOO 2WD Balance Car Robot. We can connect the smart phone with the robot via Bluetooth, and control the robot by the Balace Car APP to drive around, rotate, debug the pid, measure the speed and so on.

2.  Turn on the robot and ensure that the power supply of bluetooth module is normal.(The control switch of the Bluetooth module is opened and the on-board LED keeps flickering)

3.  Android smartphone side: [Settings] — [Bluetooth], find a bluetooth called “HC-06″,click it and enter the default password”1234” to connect with this Bluetooth.(Only available for Android)


4.  Open the OSOYOO Balance Car app and you can see as below.If the phone does not turn on the Bluetooth function, the button next to the Bluetooth switch displays will show the dark. Click to turn it on.

5.  Click “Search” to search the physical address of the bluetooth module.
