What are you soldering? The crazyradio shouldn't need anything soldered. Are you doing something special?

From the pictures you updated your OP with I can see motor M1 is shorting to R24 and M2. You should use some solder wick to remove the extra solder. I don't think this is causing the issue with the button though. Although R24 goes to U8 which is part of the power circuitry (I'm to lazy right now to ...

The question along with the comms once I got over it, is reading and writing between the two crazyflies. At the end of the protocol page, it says that I have to use null packet (0xff) to have bi-directional comms. is I am getting this correctly? As I understand it, yes. The CR only has code for PTX...

Looking at the CrazyRadio src code and the wiki page for the comm protocol should be useful.

The switch could be defective.
You may have caused a short, I would check in the area around the button on both sides of the PCB.

I hope you meant on/off push button and not switch.
Some people have broken it because they thought it was a toggle switch.

1- What could have been the issue with the M2 not spinning? Maybe the FET is bad. 2- What is the best way to solder the motors to the board? Would it be a good idea to use solder paste (as https://www.sparkfun.com/products/11789) and a small iron tip (as https://www.sparkfun.com/products/9538) ? Ye...

You can try double checking the paths to the FTDI header files in the nrfProg source code. Maybe they got installed in a different place.

The bitcraze website and wiki have a lot of good info.

The design files are on bitbucket.
