Cannot find proper ID

[cptX]

Hi, and thanks for your code. I used your code in arduino Mega2560 board with the proper modifications. I got an UDIRC drone (like this: https://www.skroutz.gr/s/14201025/Udir-c-U818A.html) but I don't have the transmitter. I desoldered the 2.4GCOB-1A module from another transmitter and attached it to arduino Mega2560 board. The problem is that I cannot bind to the drone. I think the problem is the wrong ID or the wrong protocol (sequence of data transmitted). As I don't have the transmitter I cannot check what data is sent to the module in the transmitter side.
So my questions are the following:

1. In your binding example you say "//Drone ID's (pick 4 random numbers)". Why should they get picked randomly, shouldn't it be the id the drone is expecting to see?
2. Is there a way to guess this ID somehow? Can I write a code to try all the possible combinations of ID? If yes which bytes do you suggest to change?
3. Is there from the arduino side a way to know when a bind attempt was successful? So if I make a loop to try all possible addresses to know when a bind attempt was successful and stop?
4. In the drone side, is the address also sent localy to the module from drone's microcontroller? Can I eyesdrop there to read the receiver address?

hi, how did you find the spi pinout for the module you desoldered it'll be much appreciated if you reply.
