The robot I have works with 'Bluetooth Electronic app'. I wanted to make my own app so that I could add a web cam to the robot. But i keep getting a 507 error code. Below is my code for the app.
I am confused about why it works on the Bluetooth Electronic app but not the app I created.
This is my raspberry pi python code.
