Why BLE service UUid are different in android and iphone?

Question

I'm using noble in my app, which scans for BLE devices. The issue is, the Service UUId in BLE GATT that I receive in my android is the longer UUID (i.e. 00002220000001000800000805f9b34fb), whereas in Iphone I get (2220).

I need my android to have 2220 because that's the platform I require. Is there a way to get the latter service UUID? Although, they're both the same, look at the longer one, "2220" is present from bit position 4 from left to right.

Answer 1

They are the same. A 128-bit uuid is derived from the 16-bit uuid. See What range of Bluetooth UUIDs can be used for vendor defined profiles?.
