We need to connect an Android and iPhone to our IOT device via USB.
The IOT device is a human-interface-device slave with a Silicon Labs CP2110-F01-GM chip onboard.
We need send a series of short JSON messages to the device and receive replies.
We need the Android solution to work with Kitkat through Pie. We prefer it to be an Android Studio project written in Java.
We would like the iOS solution to work with iPhone 5 through iPhone XS. We prefer the solution to be in Swift 4.
