Hey, fellow makers!
After wrestling with Bluetooth communication on the Makeblock Ranger (and managing a classroom full of them 
), I finally figured out a way to ditch the official app and take control of the Ranger with a custom Python script!
This little script lets you send commands straight to the Ranger’s original firmware, opening up a whole world of coding possibilities. Even better? You can now code for it using the Arduino IDE! 
If you’re diving into creating your own custom firmware, just keep in mind you’ll need to craft your own logic to handle commands and responses. But hey, that’s all part of the fun, right?
If you want to try it out, the code is up here: GitHub Repository
Feel free to test it out, ask questions, or just geek out with me about all the cool things you can do. Happy hacking and happy coding! 
PS : It might also work on other MakeBlock robots.
