Hello, Apple developers. I have joined the MFi certification program. My Accessory to use USB HID IAP2 communication protocol and IOS devices connected, but in the first step, the Accessory to send the following data (0 XFF, 0 x55, 0 x02, 0 x00 to 0 xee, 0 x10) for IOS devices, but the IOS devices have no response, this is probably the reason why?
The details of most MFi specifications are protected by NDA, so your question cannot be answered on this forum.
The MFi program has its own support process, the details of which you can find in the "Developer Technical Support" section of the "MFi Licensing Handbook", which you'll find on the MFI Portal.
Please submit your MFi specific question(s) using that process.
