send/receive with apple lightning - USB(OTG) to Arduino device

[taherfattahi]

Can I send/receive data via a USB OTG cable between my ios device and Arduino with this platform?
When I connect a memory device(Flash) via OTG to my iOS device I can access all files

@taherfattahi I also have this question. Have you found any solution yet?

[taherfattahi]

@curvednebula You can use MIDI controller
https://developer.apple.com/documentation/coremidi/

Only you need to implement this feature for your project I mean you can send/recieve bi-directional data between your ios device and a hardware like Arduino via USB,
Midi works like keayboard so simulate this device for you

@taherfattahi You mean this doesn't even require PeerTalk library at all? And what is running on Arduino side?

[taherfattahi]

@curvednebula Yes you can make your protocol via MIDI controller and you need to run MIDI receiver on the Arduino side

In my project, I only needed a send/receiver protocol to communicate between ARM microcontroller and Ios device via OTG cable
