I am using just works, I haven’t specified MITM on iOS or the central, is that implicit when EncryptionRequired?
I don’t know because the documentation glosses over all the complicated bits of bluetooth and doesn’t say. However, empirical evidence from your test says that it does require MITM, because that’s the only sequence I can come up with which gives you the Insufficient Authentication twice and, since the documentation for Core Bluetooth doesn’t even mention MITM my handwaving guess would be that encryption sets that requirement because that’s the more secure version (although that begs the question, what does just works pairing do apart from identify the device for the future and allow the link to be encrypted).
Can you get your central to use MITM, even with a fixed key or something dumb, see if it changes things? What’s the central implementation? |
