Use the Bluetooth_Base_UUID as the base of 128 bit UUID

[victor zheng]

Hi Team

Customer want to use Bluetooth_Base_UUID (00000000-0000-1000-8000-00805F9B34FB) as 128 bit UUID base. They can use any other 128 bit UUID base but this one. When they set the base 128 bit UUID to Bluetooth_Base_UUID in their customized service, our softdevice treat it as 16 bit UUID. So do we have any method to use Bluetooth_Base_UUID as 128 bit UUID base? I can re-produce this issue in nRF5 SDK 17.1.0.

Regards

Hi Edvin

I will ask customer to provide the data from their old device.

From previous sniffer data, we can see the difference in the "ATT Read By Group Type Response Packet". 

• when I use the Bluetooth_Base_UUID, the uuid in ATT Read By Group Type Response Packet is 16 bit

• When I use the value other than Bluetooth_Base_UUID, the uuid in ATT Read By Group Type Response Packet is 128 bit

Please let me know what they find when sniffing their old device. 

Also, did they test their app on the nRF52? Does it not work with the 16 bit format?
