When two different iOS see my BLE peripheral, they both show the same service UUID twice in the advertised data. That seems like a bug in iOS, but not all BLE peripherals show this.

The advertised data I'm setting is:

02, 0x01, 0x05, // AD Flags (General discoverable, ER/BDR not supported)
17, 0x06, 0xbe, 0xb9, 0x39, 0x48, 0x5e, 0x05, 0xaf, 0x88, 0x1c, 0x43, 0x2a, 0x4b, 0x1b, 0x1f, 0xd5, 0x75,

What I get from iOS is:

2014-05-23 17:40:10.679 MyApp[461:60b] <CameraBrowser.mm: 244>: Discovered peripheral [(null)], adv data: {
kCBAdvDataChannel = 39;
kCBAdvDataIsConnectable = 1;
kCBAdvDataServiceUUIDs = (
"75D51F1B-4B2A-431C-88AF-055E4839B9BE",
"75D51F1B-4B2A-431C-88AF-055E4839B9BE"
);
}

I'm using BTstack with a TIWI-BLE (WL1271) module.

Any ideas? Thanks!

Out of curiosity are you also sending the UUID in the scan response?
