Each of your peripherals already has a unique ID, its BDADDR.

This would have to be unique to each individually built peripheral.
I'm not sure that would be possible.

Maybe you can set an extra UUID characteristic in your peripherals or let it advertise an unique id in Manufacturer Data.

Thanks Andras,

What would be the best method to remember a peripheral?

In my case, I want to use a custom pairing method, so my app will only connect to peripherals that have been set up with that phone, and ignore others.

I have this working currently by remembering the UUID or each peripheral, however this is no good if they can change.

Thanks

Surely yes! If the BT stack is reset, new UUIDs are generated. You should use the UUID as an opaque value. It should not have any meanining to your application and your app should always check the response of the system with operations that are concerned with UUIDs.

After installing iOS 6.1.1 beta, I noticed that my app no longer recognised the UUID's of 2 bluetooth peripherals I have.

I think I read someone say that iOS creates the UUID for each peripheral based on it's MAC address and other things.

Could iOS give a peripheral a different UUID after updating iOS?

Thanks

Darren
