RGB+CW Lapm Tuya WBLC9 (BK7231T) + BP1658
My humble contribution.
https://developer.tuya.com/en/docs/iot/wblc9-module-datasheet?id=K9hgglry2jp5h
Homework tonight:
Package and marking:
disassembly:
Excellent result:
connect external power
We solder the contacts of the TP
Next are two options:
save a backup and be able to rollback or just flash
Create and save a flash memory backup. You need a programmer SPI memory, for example
inexpensive CH341A.
Firmware through any UART port available to you with 3.3v levels (for example)
We transfer the programmer CH341A to serial mode, remove the jumper (or any other, which is available)
run the program for the firmware (download the program and the latest firmware )
specify your file with the program and your com port
Next, we connect to the access point, go to the address 192.168.4.1 and make settings
The main ones related to the lamp and the chip:
Configure module:
P24 BP1658CJ_DAT
P26 BP1658CJ_CLK
Configure General
set Flag4 ( restore on power and flag12 )
Change Startup command text::
BP1658CJ_Map 2 1 0 4 3
Setting up MQTT ( ip, topic, username, password )
Home assistaint (configuration.yaml ):
Good luck!
P.S.
Huge thanks to btsimonh and Refuhr for their help!

We heat up
And with both hands, just gently break it in half.
The main thing is not to damage your hands, eyes, body, as well as the lamp body and the ceiling.
remove pimpochka
With a blunt knife, gently move the base in a circle
cut off white snot
with a thin but strong screwdriver, push the disk out with LEDs
