Hello,
I'm building Raspberry Pi/Arduino quadcopter that will be controlled by android tablet. Also, Raspberry Pi has Pi camera that broadcasts live video signal.
I know that this is enormous project but I need help with only one thing: communication between Raspberry Pi and Arduino.
I've created android app that send sensor data based on RCSerial protocol ($M> [length] [Protocol code] [data] [checksum] ) to Raspberry Pi via WIFI(UDP packets) and Raspberry Pi send it to Arduino via USB cable.
Problem is that Arduino receives data but not work by it. Arduino is programmed with standard MultiWii code.
Serial on Arduino works on 57600 baud, connection between Raspberry and Arduino is 57600baud. Should I create connection between tablet and Raspberry on 57600baud?
I hope that you've understanded most of the situation. Thanks for your help in advance
It sounds to me as if you need some code on the arduino to parse the commands sent to it from the RPi. I'm not sure if the MultiWii code even does this but then again I've never even seen the mult wii code:-)
Hope that helps!

MultiWii code has code for parsing given data. Also, I've created data packets with flight data exactly how they should look. Raspberry Pi receives UDP packet, collects the data and sends it to the arduino. RX LED on arduino flashes, so, it receives data. Is the problem in different working frequency? Or something like that?
Yes, serial baud rate is the same: 57600 on Raspberry Pi and on Arduino.
But, I don't have standard serial between android and raspberry pi. I'm just sending UDP packets every 75ms. I was told that isn't a problem. Is it?
