Controlling LED strip with WB3L chip not possible
i'm not sure if this is the right place for this
Yesterday I flashed OpenBeken on my WB3L (https://docs.libretiny.eu/boards/wb3l/#usage) chip. The chip is in a Meko LED Driver (MKP006C0160BLTG) An LED strip is connected to it (RGBWC) I have tried several configurations in Openbeken, including the GPIO Doctor. But the LED strip does not respond. It hangs on the same color that was set with the old/original firmware. An important info! There is another chip installed on the back. This is probably for the 2.4GHz remote control. Do you have any experience with this? Do I have to set the config in OpenBeken to control the other chip? I just don't know how.
Thank you!
I found this document for the other chip http://wiki.telink-semi.cn/doc/ds/DS_TLSR8367-E_Datasheet%20for%20Telink%202.4GHz%20RF%20System-On-Chip%20Solution%20TLSR8367.pdf
What is the App name? In case it's a Tuya device, you can dump the firmware and read the device configuration using GUIFlasher or ltchiptool. I am not familiar with the Telink chip but if it's a Tuya device, you might be able to communicate with it using TuyaMCU of OpenBeken.
If you flashed the Openbeken firmware without dumping the factory firmware first, search the forum for the same device, and post the teardown photos there, you'll get help faster.
Thanks for your answer. I dumped the firmware before. But the tool was not able to extract some config (see Screenshot)
I will attach the dump readResult_BK7231T_QIO_2025-12-1-18-32-00.zip
It's a TuyaMCU, I managed to download it's Schema from Tuya using ltchiptool, There are Chinese chars. in the mode names:

I asked ChatGPT to translate the chinese symbols
开关 - Switch (On/Off) 模式 - Mode 亮度值 - Brightness value 冷暖 - Cool/Warm (Color temperature) 彩光模式数据 - Color light mode data 情景模式数据 - Scene data 炫彩模式 1 - Flash scene 1 (or: Colorful mode 1) 炫彩模式 2 - Flash scene 2 (or: Colorful mode 2) 炫彩模式 3 - Flash scene 3 (or: Colorful mode 3) 炫彩模式 4 - Flash scene 4 (or: Colorful mode 4)
For the first test i added the autoexec.bat with this configuration
startDriver TuyaMCU setChannelType 1 toggle linkTuyaMCUOutputToChannel 1 1 1
I'm now able to turn LED strip on/off
Probably this can help: https://www.elektroda.com/rtvforum/find.php?q=tuyamcu_setupLED
Thank you.
I don't understand how to define the purpose of the channel
I have tried this autoexec entry
startDriver TuyaMCU tuyaMcu_defWiFiState 4 tuyaMCU_setupLED 24 0
I have now the nice brightness, rgb and colour temp options on webinterface. but they don't change the real light.
How can i tell this config that it needs to use channel 3 for brightness and channel 4 for colour temp and colour itself on channel 5??
