This is a short teardown and flashing guide for ANTELA ceiling lamp PLAFONIERA 20W
Wenkman - 20.01.2023
Brand: Immax
Model: AN-EU-CL260-WIFILIC-RGBCW-TD-01
Chip: BK7231N
LED Driver: SM2235EGH
Shop: Amazon
I searched Amazon for a ceiling light made by Tuya, found the above, ordered it, arrived 10 days later and immediately disassembled it.
I quickly found the "3.3V,GND,RX,TX" pins on the underside, but still wanted to try the tuya-cloudcutter first.
first connected the lamp to the SmartLive app to find out the current firmware
Then immediately disconnected the lamp again.
I have now followed this guide again.
I pulled the current firmware for the BK7231N from Github
and then started the flashing with the start command:
After flashing, you should definitely check which version was installed, it must be at least 1.15.345
otherwise update under OTA
after that define the pins
now just create an autoexec.bat and add the following code (for BGRCW customization).
then just confirm with the button "Save, Reset SVM and run file as script thread" and the lamp is ready.
I hope I could help someone with this.

Thank you, it's good to see that SM2235 driver is useful for users. SM2235 driver is very similar to SM2135, but it offers a 10bit colour precision , which is better than 8 bit in SM2135 version. So... [Read more]
