We just finished developing an iOS app at the company I work at that uses the Muse headset. As Muse only connects to iOS devices through Bluetooth, I was under the impression that we did not need a MFi Product Plan ID number. However, I reached out for clarification from Apple, and it looks like we do in fact need this ID number.
According to the reply I received, due to the presence of the UISupportedExternalAccessoryProtocols key in the Info.plist file and linking to ExternalAccessoryFramework, the MFi PPID is required from the accessory manufacturer. (As a side note, the ExternalAccessoryFramework is not directly linked by our app, so it must be linked/included in the Muse framework?).
What is the process of getting the MFi PPID from InteraXon? I tried emailing firstname.lastname@example.org, but it was returned immediately.
