Controlling LED strip with WB3L chip not possible #1509

I found this document for the other chip |
|
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 |
|
It's a TuyaMCU, I managed to download it's Schema from Tuya using ltchiptool, There are Chinese chars. in the mode names: {

Thanks! I asked ChatGPT to translate the chinese symbols 开关 - Switch (On/Off) |
|
Check this guide: |
|
For the first test i added the autoexec.bat with this configuration startDriver TuyaMCU I'm now able to turn LED strip on/off |

Please consider posting your findings to a new thread on Elektroda. |

Probably this can help: https://www.elektroda.com/rtvforum/find.php?q=tuyamcu_setupLED |
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!
