[Solved] Custom Binary Request for Ai-WB2-12F (BL602) with VEML7700, IR, and Relay Drivers

How can I get a BL602 binary for Ai-WB2-12F with VEML7700 support for my home automation project?

IR is already enabled on the board, but the standard OpenBeken binaries do not include a VEML7700 driver, so you need a build that adds that sensor driver or another supported sensor instead [#21860734] [#21860738] A custom BL602 binary was provided in the GitHub Actions artifacts, and the suggested driver command is `startDriver VEML7700 [SCL-pin] [SDA-pin] [chan_lux] [chan_white]` [#21861377] The driver was also tested in the I2C simulator and reported working there, with `Sim_AddI2Csensor type=VEML7700 ...` and `startdriver veml7700 13 23 5 4` producing valid lux and white-channel readings [#21861377] If VEML7700 cannot be used on your hardware, LTR-303 and LTR-329 are mentioned as already supported alternatives [#21860738]

    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

LABEL_AI_GENERATED
The discussion concerns a custom firmware binary request for an Ai-WB2-12F board based on BL602 for home automation. IR support was already available, but the missing VEML7700 light sensor driver was the main issue. It was clarified that OpenBeken did not yet include a VEML7700 driver, while supported alternatives such as LTR-303 and LTR-329 were suggested if the sensor could be swapped. A test build with a VEML7700 driver was later provided for BL602, including I2C simulator support and a startup command for the driver. The topic ended after the system was reported working, although the board was eventually replaced with an ESP32-S3 board to achieve all desired functions.
