We have an existing pos solution, where payment is done via an app and a qr code.
Now we need mdb protocol integration. So the job is as follows.
1. Come up with the hardware changes/ upgrades needed in order for our esp32 board to communicate with a mdb vending machine.
2. Recieve the price from the mdb machine, when a btn is pushed.
3. Be able to emulate a payment to the machine.
Above is the requirements. Please don't bid on this project unless you got previous experience with mdb protocol and esp32, really im tired of people wasting my time.
Payment will be only over freelancer.
