[BL602] [SM2135] Surplife APP RGB+WW+CW bulb

This a $5.2 bulb I got from Amazon.sa
Unfortunately, this bulb seems to be a no name brand but it does use the Surplife APP. Sorry I don't have further information about it.



I was hoping to get BK7231T or BK7231N just so I can try Tuya Cloudcutter but this bulb came with a BL602 module BL-M5 V1.2
The bulb also uses a SM2135 LED Controller


Since this is a BL602 chip I had to remove the module from the board to get to the flashing pins on the back of the module



I used a soldering iron to remove it but I think it would be easier with a hot air station.
To flash the chip, I used USB to TTL adapter

TX -- RX
RX -- TX
Ground -- Ground
3.3 V -- 3.3V
Boot -- 3.3 only during flashing (I see other post saying a 10k resistor should be used but I couldn’t get the flashing complete unless I connected boot to 3.3v directly)

Here is more detailed post

After flashing this is the pins for this bulb



This is the second bulb I have with BL602 (first on is a sonoff B05-BL-A19), with both bulb the brightness is low after flashing OpenBeken.
I used (BP5758D_Current 50) command for the sonoff to adjust the brightness

But for the SM2135 controller I used the command (SM2135_Current 6 2)

But still the RGB collors need to be calibrated and I havn't done that.
