based Arduino or Esp32 MDB vending machine cashless vending code.

I have a project on Arduino (exapmle Mega 2560 ).

The Arduino should act as a cash receiver and send exactly the amount that I deliver via Bluetooth to the balance. I have a working code, but it only works on a few coffee vending machines. Where it does not work, it blocks everything with one code:

#define CSH_ACK 0x0100 // Acknowledgment, mode bit set.

I also have an insulator circuit.

The fact is that it works on one device. I think my code works on level 1 alone.
