Description dj_technohead 2013-09-28 01:02:21 UTC
Passing in a guid to the ScanForPeripherals method results in a run time exception:

"Objective-C exception thrown.  Name: Invalid Object Reason: Argument 50890202-A8E5-FBFF-98FD-FBEFF8E5D3BF is invalid"

What happens if you try a CBUUID ?

>   var c = CBUUID.FromString ("50890202-A8E5-FBFF-98FD-FBEFF8E5D3BF"); 
>   var a = new CBUUID [] {c};

That appears to work (doesn't cause an exception). But I first tried the method that took a Guid and thought I should report the exception.
Comment 3 Sebastien Pouliot 2013-09-29 10:33:15 UTC
Its a good report :) I wanted to be sure the issue was with the Guid version (and not something else) since I know people are using this inside their applications.
Comment 4 Sebastien Pouliot 2013-09-30 10:15:58 UTC
The issue is that depending on how the `Guid` is created, from string or from a byte array, the internal representation will (or won't) match the one of `CBUUID`.

We're looking into this but, right now, you're better using `CBUUID` (and FWIW I think we should obsolete the old `Guid`API).
