Ambient Light - Add BLE Protocol Support for DUOCoStrip / SymphonyLight

cifu

Dear DUDUOS Development Team,

I am using a DUDU7870 head unit with DUDUOS and an ambient light kit using the DUOCoStrip / SymphonyLight controller via Bluetooth (BLE).

Device Details:

Head Unit: DUDU7870 (UIS7870)
Ambient Light Bluetooth Name: DUOCoStrip
App required to work natively: SymphonyLight / duoCo StripX

Current Issue:
The head unit successfully pairs with DUOCoStrip over Bluetooth. When running the third-party app "SymphonyLight" directly on DUDUOS, light color changes work perfectly. However, the native DUDUOS Moodlight app connects to the device but fails to send color changes or mode commands due to an unsupported BLE command payload.

Request:
Please add support for the DUOCoStrip / SymphonyLight BLE protocol service UUIDs and write characteristics in the native DUDUOS Ambient Light app settings.

Thank you!

Thanks @dudu-lai , for moving the proposal to the right place.
Do you think it’s feasible to integrate this ambient light at some point?
I would really appreciate it.

Sorry, I don't quite understand what you mean. Do you mean that there is a problem connecting your ambient light here in the settings of DUDUOS - external devices - ambient light?

Dear DUDUAUTO Team,

There is a misunderstanding regarding my ambient light issue on DUDUOS 3.7 (DUDU7 / UIS7870). The issue is NOT a Bluetooth hardware or connection failure, but a BLE Data Payload / Protocol Mismatch in the native DUDUOS Ambient Light app.

Device Specs:

Head Unit: DUDU7 (UIS7870) running DUDUOS 3.7

Ambient Light Module: DUOCoStrip / SymphonyLight (Bluetooth BLE)

Key Diagnostic Points:

Bluetooth Pairing Works: The ambient light connects properly under DUDUOS Settings > External Devices > Ambient Light.

Commands Fail in DUDUOS App: When trying to change colors, brightness, or turn ON/OFF from the native DUDUOS Ambient Light app, the lights do not react at all.

Hardware & BT Stack Confirmed Working: If I install the third-party app SymphonyLight (or duoCo StripX) directly on the DUDU7 head unit, it controls all lights, colors, and modes perfectly via Bluetooth.

Conclusion & Request:
The Bluetooth hardware communication between DUDU7 and the LED controller works 100%. The problem is that the native DUDUOS Ambient Light app is sending an incompatible hex payload/UUID command that DUOCoStrip cannot parse.

Please add support for the DUOCoStrip / SymphonyLight BLE protocol (Service UUID & Write Characteristic) in the native DUDUOS Ambient Light app in the next update.

Thank you!
