Sending and Receiving Data from an iOS App to a DEX Vending Machine
Budget: $250 – $750 USD
I am currently working on a project where I need to implement the flow to send and receive invoices from a DEX vending machine on iOS. To simulate the connection to a vending machine, we are using a Redpark serial cable: https://redpark.com/dex-cable-ios-dsd-l2-dex-iphone-ipad/.
With this cable, I connect to a serial/USB adapter and simulate a vending machine to try sending invoices and receiving invoice adjustments in the applications.
Redpark provides an SDK(https://redpark.com/wp-content/uploads/2024/04/RedSerial-SDK-v1.0.9.zip) and demo software for sending and receiving data, which helps in understanding the basics. However, I am currently unable to find the correct sequence to successfully send and receive invoices to a DEX machine. I understand that there is a protocol and control characters required for communication, but so far, I have not been successful in the implementation.
I am looking for someone with experience in implementing the transfer protocol for consultancy or for the development of this implementation.
