After my quad got stolen, I started to think if it's possible to implement any sort of software or hardware protection like password lock or something. Do you think it is possible to implement?What I have in mind is a configurable set of values on all (or some) channels that flight controller expects to see upon power on. If this "code" is incorrect, it should be impossible to fly or establish any communication at all. The code should be stored in EEPROM or something so reflashing would not help. Even better, if it's possible to "lock" any flashing altogether on a hardware level and unlock it with a password, but I don't know if that is possible at all. I know there is some write protection on stm32f427 but have no idea how it works.Also, is idea is for majority of users, so that generally people would not be able to by-pass this protection but not too tight for advanced users.
