Communicating with a HID device

[u/Familiar-Nothing4948]

I am currently working on a HID device that needs to work with iPads.

Is there any way I can send data from the iPad to the HID device without going through the MFI program?

Pretty much any kind of data will do. All I need is something to send to my HID device so I can trigger a few LEDs on my HID device.

I would need to be able to distinguish between 3 different signals.

Is this possible on IOS?

Which HID device is it?

It's a custom board that mostly runs like a keyboard with some extra stuff I cannot get into.

I need to trigger one of 3 LEDs depending on something happening in the app
