Hello, I want to try develop hearing aid based on stm32 with BLE Module. If I want to only stream music from iPhone, does I need mfi certification? And I want to develop application with changing program on device
BLE Device connect to iphone
I am not sure what you mean by hearing aids which only stream music. Earphones?
While BLE modules can be used without the need for MFi certification, BLE-enabled MFi Hearing Aids are part of the MFi Program.
In any case, https://mfi.apple.com may have some answers, and you can contact support if you are still not sure whether you need to join the MFi program.
