Resources for hardware developers?

Good morning, Apple devs.

I'm looking for resources and help designing a BLE hardware peripheral that is compatible with iOS and iPad. I've seen the MFi program, but I've also seen plenty of peripheral devices that work with iOS and iPad that are not listed in the MFi compatibility lists.

Can anyone refer me to the proper channels to get support for development of a hardware device?

Thank you.

BLE is not covered by MFi rules, and can be manufactured and used without joining the program.

Accessory Design Guidelines for Apple Devices explain the recommendations and requirements for creating compatible hardware and accessories, including BLE devices.
