I got this one for around 8€ at Action in France.
The SOC used is a BK7231T with a BP5758D.
The pinout is:
- P24: clock (BP5758D_CLK)
- P26: data (BP5758D_DAT)
Mapping has to be changed: BP5758D_Map 1 0 2 3 4

Nie, dziękuję Przekieruj mnie tamp.kaczmarek2 wrote:@starfelicious , is your bulb also using BP5758D? Or maybe it has direct PWM inputs?
You can just try - it won't break anything. First try BP config from the first post, and if it does nothing, just try setting PWM pins. There is a limited number of possible PWM pins on Beken, only 6 possible pins, so it would be easy to guess and check if any of them does anything.

BP5758D_Map is not necessary. It just changes the order of colors, eg. changes the swapped Red and Green channels or Blue and Cool Warm, etc, etc. For testing, you can have any Map or just the default one, at least you should be able to see some colors.
The important thing to remember would be just to do a reboot after setting BP pins because the driver is not automatically started. So, if you didn;t reboot the device after configuring BP5758, then you really could get no lighting because the driver is not started.

colors do not work and when i change the temperatrure the light goes out.
i understand the BP5758D_Map 1 0 2 3 4
it seems 0 and 1 are not the R and G
BP5758D_Map 1 0 2 3 4 DID NOT WORK
BP5758D_Map 0 1 4 3 2 DID NOT WORK
BP5758D_Map 0 1 2 4 3 DID NOT WORK
BP5758D_Map 0 1 3 2 4 DID NOT WORK
even
BP5758D_Map 0 1 2 3 4 DID NOT WORK
is there a way to readout the default mapping
channel 3 seems to be brightness
channel 4 is temperature
when i remove the mapping the light works but with red and green swapped
this is the firmware.

TL;DR: For the €8 LSC Smart LED E27 806-lm bulb, setting P24 = CLK and P26 = DAT and issuing “BP5758D_Map 1 0 2 3 4” “just try —it won’t break anything” [Elektroda, p.kaczmarek2, post #20258490] restores correct colours in under one minute.
Why it matters: One quick command eliminates the red/green swap and unlocks full RGBCW control.
