Tuya BLE SDK

[jumpingfool]

Hi,

We are looking at porting the Tuya BLE SDK to the Nordic platform and on reviewing the documentation we have identified that the SDK uses two 16bit service UUIDs:

- 0x1910 for data transfer

- 0xA201 for advertising

More details here:

https://github.com/TuyaInc/tuya_ble_sdk#the-concepts-of-tuya-ble-service

On checking the BLE SiG 16bit numbers document it seems these service IDs are not allocated.

How is it that Tuya are able to use these UUIDs for their services? Could this cause any problems later with Bluetooth SiG qualification?

That seems like a violation of BT?

I can see from the release notes:

https://github.com/TuyaInc/tuya_ble_sdk/blob/9a22cd15983a36f749fea860292086bd6951f741/CHANGELOG.md

Changed

• Use the new Tuya exclusive service uuid and characteristic uuid.
• Changed advertising packets format to adapt to the new service uuid.

I guess you need to contact them on what this means?
