Ah seems like we need to fix the test data for the following tests:

BluetoothTest.AdvertisementData_ConnectionDuringDiscovery
BluetoothTest.AdvertisementData_Discovery
BluetoothTest.AdvertisementData_DiscoveryDuringConnection

+            [NSData dataWithBytes:(unsigned char[]){} length:0],
         [CBUUID UUIDWithString:@(kTestUUIDImmediateAlert.c_str())] :
-            [NSData dataWithBytes:(unsigned char[]){0} length:1]
+            [NSData dataWithBytes:(unsigned char[]){0, 2} length:2]
       };
