[BK7231T] E27 A60-Bulb LED RGBCCT
This is a short teardown of the E27 A60-Bulb LED RGBCCT which is based on BK7231T
Basic Informations:
Brand: Tuya
Model: E27 A60-Bulb LED RGBCCT
Chip: BK7231T (WB2L)
Vendor: https://shopee.com.my/product/68463208/6454092983?smtt=0.5847450-1663473183.9
Got it discounted from a local marketplace, but I'm pretty sure the same bulb is available in aliexpress provided it's in the same packaging as below.
My unit was sold as defect bulb, apparently there's a defect with the power supply that causes the board to restart and flicker for 1 sec that happens randomly but not frequent.
Is there a way to have to turn it back on from previous state/color/brightness when the random restart occurs?
On stock firmware, it does resume when that happens but it just turns off on openbk.
The pcb is sealed with silicone which makes it difficult to tear down this bulb without destroying the case.
It's recommended to flash using cloudcutter, you can flash it via ota by selecting Generic Profile - E27 A60 RGBCWW
Pinout:
Pin 26: PWM 1
Pin 24: PWM 2
Pin 6: PWM 3
Pin 8: PWM 4
Pin 7: PWM 5
