Hello, Thank you for invitation, but this is not a fully repetition of previous projects. Couple years ago I designed a GSM-enabled device for vending machines. It has both DEX and MDB support. But it has STM32 MCU and not Arduino inside. My current project indeed for Arduino but includes neither any GSM communication nor MDB bus support. It is only about reading of DEX audit data from vending machine. Please also note that MDB bus requires a special physical layer, it is not like DEX which is actually just a RS232 interface. Could you please clarify why you specified DEX or MDB? They are completely different on their purposes. Thanks, ilya
