Not now. What I really need is HOW bluetooth works in self balancing robot and NOW, I assume that Bluetooth CAN NOT control the bot AT ALL. Why? because the bot has been fully handled by mpu6050.
I tried to PICK the mpu6050 device from the bot and I held it - I saw the bot acted "brutally" (since I shake the mpu device). That means that NOTHING can control it but mpu6050.
So, what bluetooth can do is to CHANGE the current setpoint into "more" or "less". "more" means "forward" - "less" means "backward".
Is it correct? (I ask you because you're the expert and I need it)
