Bluetooth Robot Control is a free Android application developed by RobotClass.ru that allows users to remotely control their Bluetooth robots and cars. The app has two main modes of operation: Continuous Command Flow and Uppercase/Lowercase Command.

In Continuous Command Flow mode, the app sends a continuous flow of characters via Bluetooth while the user presses the button. On the other hand, in Uppercase/Lowercase mode, the app sends an uppercase character when the user presses the button and the same lowercase character when he releases the button.

The app offers a list of commands, including forward arrow, backward arrow, left arrow, right arrow, buttons A, B, C, D, and speed slider. The app also comes with an Arduino example program that can be used as a reference for developers.

Overall, Bluetooth Robot Control is a useful tool for anyone who wants to control their Bluetooth robots and cars remotely. It’s easy to use and offers a wide range of commands.
