Hello,
I have been trying to get the BlueSMiRF bluetooth module to work correctly with the Pololu Micro Maestro 6 servo controller and I’m getting to the point of frustration. I have two servos hooked up to the controller, and when I command the servos to move via blue tooth from my computer, they seem to twitch back and forth and in random positions where they are not told to move to. In my attempt to solve the problem I have tried different configurations with powering the blue tooth and servo controller. The first thing I did was I soldered a jumper wire between the 4.8 v 10Ah battery servo power and the VIN header on the Micro Maestro, this powered the controller as well as the servos. I also hooked the blue-tooth module up to the same pack and I’m getting the twitching of the servos. I then hooked the bluetooth power up to the maestro’s 20mA regulated output, and still got the same twitching of the servos. The next thing I tried was I took the jumper wire off the controller, and had the 4.8 volt battery just powering the servos, and two separate 1.2 v NiMH battery’s at 2500 mA apiece, each stepped up to 5v 100mA output for the controller and bluetooth. When I tried this, I get nothing but a serial protocol error on the servo controller when I attempt to connect. I have looked over and assured the RX/TX wires are correct and everything, I set the correct baud rate and everything. When I eliminate the blue tooth completely, and just power the controller by USB or battery, everything runs great and the servos move the way they should.
