    Hello, I am posting some photos of the inside of the 24W spectrum led projector, I am looking for the right openbk firmware to flash it
    how to make the firmware?
    I have 3, I opened this one because even when turned off the LEDs remain slightly lit, and when it is turned on it is impossible to get red light
    broken for broken if it can help
    thanks if someone could explain the procedure to me

    AI: Have you attempted to flash any firmware on the projector before, and if so, what version is currently installed?
    no modified firmware only with spectrum android app in ap mode 5x on/off twice firmware 1.3.3

    thanks, I'll look but I don't speak Russian... under the metal cover there is a bk731t microcontroller is that it? can we reprogram it like on an arduino when it is disassembled? the problem is that to disassemble the led projector everything is glued (I had to break the glass to use leverage and disassemble it.... and for the other two can we flash it when it is in Access point mode?

    I think most of the guides are in English

    yes, the BK7231T is one of the chips supported by OpenBeken

    it depends what firmware version it's running. with a backup of one of the firmwares you can tell if the rest can be done without dismantling (assuming theyre all the same)

    Hello, flash ok, acces a l'interface ok

    Device seems to be using WB3L module, which is BK7231T chip.
    - LED Red (Channel 1) on P8
    - LED Green (Channel 2) on P24
    - LED Blue (Channel 3) on P26
    - LED Cool (Channel 4) on P7
    - LED Warm (Channel 5) on P6
    Et après je suis un peu perdu...je ne trouve pas l'éclairage de 10 à 100 %

    from the pic it looks like all your assignments are currently relays

    also, that config extraction list doesn't seem to be the same as the result from the latest Easy Flasher v5, which is

    also note that OBK does not support microphone/sound reaction effects

    Thank you
    yes, I think that for the microphone it was a function on the smartphone application with the telephone microphone...
    No connection possible in bluetooth?

Topic summary

The discussion revolves around flashing OpenBK firmware onto a 24W Spectrum LED projector, which utilizes a BK7231T microcontroller. The user seeks guidance on the flashing procedure, particularly after experiencing issues with the projector's LEDs, such as them remaining slightly lit when off and the inability to produce red light. Participants suggest starting by backing up the existing firmware and refer to resources like GitHub and Elektroda for relevant guides. The WB3L module, based on the BK7231T chip, is identified as the core component. Configuration details for the LED channels are shared, and there are inquiries about the possibility of flashing the firmware while the device is in Access Point mode. The conversation also touches on the challenges of disassembling the projector due to adhesive and the potential for Bluetooth connectivity.
