| Hello developers, has anyone tried to discover included services of a service yet?
I'm talking about
[peripheral discoverIncludedServices:nil forService:service];
On iOS 7.1.2 it simply crashes if the included Service is a 16 byte UUID service. If the included Service is a 2 byte UUID service and the included characteristics are 2 byte ones, everything is fine and the delegate
- (void)peripheral:(CBPeripheral *)peripheral didDiscoverIncludedServicesForService:(CBService *)service error:(NSError *)error
is called successfully. If the Included Service UUID is a 16 byte one, the app crashes between dicoverIncludedServices and the delegate call didDiscoverIncludedServicesForService showing somithing like this in the log:
*** Assertion failure in -[CBUUID initWithData:], /SourceCache/CoreBluetooth/CoreBluetooth-109/CBUUID.m:199 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Data <30ced314 00000000 00000000 00000000 13d2e876 2067d414 00000000 803de314 141e8700> does not represent a valid UUID' *** First throw call stack: (0x2dbe2f83 0x3845dccf 0x2dbe2e5d 0x2e590d5b 0x2d90b4e1 0x2d90b6cd 0x2d90a067 0x2d90a597 0x2d909b99 0x2d909c7b 0x2d909d61 0x2d905fab 0x2d90e64b 0x38945833 0x3894581f 0x3894c49f 0x2dbad8a1 0x2dbac175 0x2db16ebf 0x2db16ca3 0x32a70663 0x3046314d 0x90a85 0x3896aab7) libc++abi.dylib: terminating with uncaught exception of type NSException
My Gatt sample looks like this:
Service 832C3299-2AE2-4C91-A25C-49E7FE5247F6 | +-- Service EF1716A9-DD1D-477B-8355-83793D8C92EA | | | +-- Characteristic 832C3299-2AE2-4C91-A25C-49E7FE5247F6 | +-- Characteristic 677C006F-8FE1-4477-B2F6-D16CB2336678
Any hints? This looks like a bug in CoreBluetooth. Can anybody confirm this?
