This setup creates a WiFi access point that looks like a real SG500 drone. The app can connect to it and will think it's sending commands to the drone. Instead, you can analyze the commands.
Usage: use setup.sh to start the access point, then connect your android
device to it. You may need to set a static IP like 172.16.10.xx (xx != 1).
Then launch drone.py to act as a real drone.
these are described over here.
Command syntax: 0xFF
checksum is 1 byte, cmd is 9 bytes. sum(cmd) + checksum == 0xFF (mod 256).
all trims default to 0x10 and range from 0x00 to 0x20.
cmd[0] = ? (always 0x08) cmd[1] = left y 00..FF = bottom..top cmd[2] = left x 00..7F = left..right cmd[3] = right y 00..7F = top..bottom cmd[4] = right x 00..7F = left..right cmd[5] = ? (0x80 -> auto altitude enabled. 0x40 -> gyro button in options (pulse), 0x00..0x20 = left x trim (left..right)) cmd[6] = right y trim 00..20 = bottom..top [sic!] cmd[7] = right x trim 00..20 = left..right cmd[8] = flags (0x40 -> auto launch, 0x20 -> panic, 0x80 -> auto land, 0x10 = compass button in options, 0x03 mask is 0,1,2 for 30%,60%,100% button)
