Hello,

yes I noticed the same problem!

The UUID is just reversed, if you check it ;)

But I do not know why it happens!

Hi,

Is there anyone faced the problem that when CBPeripheralManager Advertising a 128 bits CBUUID in CBAdvertisementDataServiceUUIDsKey , the order of the CBUUID become different from it's original value?
Like when I advertising like this 

     NSDictionary *advertisingData = @{CBAdvertisementDataServiceUUIDsKey : @[[CBUUID UUIDWithString:@"EBA38950-0D9B-4DBA-B0DF-BC7196DD44FC"]]};
    [peripheral startAdvertising:advertisingData];

The actual thing it advertising is FC44DD96-71BC-DFB0-BA4D-9B0D5089A3EB .

This problem only happened if I try to use 128-bit UUID for advertising, 16-bit works great. So is there anything wrong on my own side?

Best Wishes,
Khaos Tian
