    Hi,
    I am trying to use Ai-WB2-12F (BL602) for my home automation project. I need to use VEML7700 sensor, IR control, and relay, but the standard public binaries do not have these drivers enabled. Could someone please generate a custom binary for me?
    Thank you!

    IR is already enabled, but there is no VEML7700 driver in OpenBeken.

    Hello.
    Thank you for your quick reply. I know that IR is ready on this board, and I need to solve the problem with VEML7700 driver. I have tried to install but I am not skilled enough.
    Can you help me?

    Someone who has it would have to write a driver.

    If you can swap it, LTR-303 and LTR-329 sensors are supported

    Hello.

    I am aware of this. But I wasted all my energy for two days on how to create a bin file that contains the necessary drivers. AI advised me to contact this forum.

    I got a couple on order but I don't expect them for 5-7 days. @p.kaczmarek2 maybe has something in his leave?

    Which IR driver do you need?
    I tried a VEML7700 driver
    Since I don't have them, I added them to the I2C simulator and it works there.


    Maybe you can try in real life? You can fetch the binary for BL602 here (must be logged in to get the artifacts)

    So the driver is working on your system?

    Finally, I gave up the possibility to update this board with all the functions I wanted. I bought original ESP S3 board. With this board everything works fine.

Topic summary

✨ The discussion centers on creating a custom binary for the Ai-WB2-12F development board based on the BL602 chip, intended for a home automation project requiring support for the VEML7700 ambient light sensor, IR control, and relay drivers. While IR functionality is confirmed to be enabled in the standard OpenBeken firmware, there is no existing driver support for the VEML7700 sensor. Alternatives such as LTR-303 and LTR-329 sensors are supported by OpenBeken. The original poster seeks assistance in generating a binary including the VEML7700 driver, but no ready-made solution is available. One respondent mentions awaiting hardware delivery and suggests a community member might have relevant resources.
