What is your problem?

I'm building a system that connects devices together via BLE. The phone will get the MAC address of device A and send it to device B. Device B uses that MAC address to scan and connect to device A.

I built it for Android and it works fine.

However, I was building for an iOS device when I noticed that: I can't get the device's MAC address (remodeId returns a strange UUID and it's not a MAC address).

How to get the device's MAC address??

Is there a parameter defined specifically for each device so that when Scanning, that parameter will be used to distinguish devices from each other (all devices are advertised with the same UUID)?

ios does not allow this.

mac address is hidden for privacy reasons by Apple.

@chipweinberger Greetings sir,
regarding this constraint, it means that if I store (in local device store for example) that strange uuid, I could not use that uuid for later reconnect to it (for example, in an app which list "favorite" or "recently" connected devices? ) in ios?

[chipweinberger]

correct.

ios will occasionally change the randomly generated uuid.

i'm not sure how often it changes.

Thanks sir, interesting, so, we could say this issue is related to the operative system (IOS) rather than flutter itself? I mean this "problem" is also expected to occur for example in swift? @chipweinberger
