V949 interface to Arduino/AVR

Hello, I'm interested in interfacing the V949 to an Arduino (or AVR) board. I want to be able to control the RC wirelessly using the board. I've done some research and found out that the a7150 chip is used for communication. My first question is, is the a7150 compatible with the nrf24l01 (I have a couple of them lying around)? Most websites report so and I'm confused.

Second question is about the protocol, is it available somewhere? I don't own a logic sniffer so I can't poke around myself. Sample code will be extremely helpful!

(I also posted this thread at rcgroups.com, but I feel this forum is more appropriate. I found this post which is exactly what I need, but for another model)

Thanks for the help!

I thought it was compatible because many sellers list them as the same. I guess its a search trick. I've ordered a couple of A7105's and they should arrive in about a month.

Thanks for the link, seems that it has the answers I'm looking for.

Keep it up!

Early days but does work.

Really nice project. I think I understand how the A7105 must be initialized and the binding sequence. What's not clear for me is the data packet structure and encoding(?).

The project is an (RX) receiver, I'm looking into making a TX. It's not very different, though.

Another quick question:
According to the code there are 21 packets (21 bytes). This is how they are unpacked:

for (i=0;i<8;i++){
word_temp=(packet[5+(2*i)]+256*packet[6+(2*i)]);

if ((word_temp>900) && (word_temp<2200))
Servo_data=word_temp;
}

rcData[ROLL] = Servo_data[0]; //aileron
rcData[PITCH] = Servo_data[1]; //elevator
rcData[THROTTLE] = Servo_data[2]; //throtle
rcData[YAW] = Servo_data[3]; //rudder
rcData[AUX1] = Servo_data[4]; //aux1
rcData[AUX2] = Servo_data[5]; //aux2
rcData[AUX3] = Servo_data[6]; //aux3
rcData[AUX4] = Servo_data[7]; //aux4
}

I'm not sure what the code in bold does. Does anyone have any clues? Is it "encrypted" in some way? Also, why does it happen in a loop?

Thanks for all your help! I truly appreciate it.

This should help more then code.google.com/p/rc-ppm-2-spi/
