How did you connect the flasher? 1TX and 1RX should work. Then just do power on/off to reboot.

cijoml · Answer

That's what I have done but chip did not reboot. Also tried ground CEN without success. May be the problem with capacitor I saw some video...?

p.kaczmarek2 · Answer

But capacitor here would be on 12V line and not on 3.3V... maybe try swapping RX and TX?

Did you flash any other devices with your setup?

Do you power your strip with a reliable 3.3V power supply?

Can you show a photo of your setup?

cijoml · Answer

Of course I tried swapping rx and tx. Yes I have flashed many Tasmota firmwares with this setup. No problem with setup. I used speed 921k

p.kaczmarek2 · Answer

Yes, but what about BK7231? It may have slightly different requirements and I remember some topics from our forum where people used too weak power supply (directly from USB to UART converter) or the USB to UART converter itself was not too good/

cijoml · Answer

this is my first attempt with this firmware

Hello I was successful flashing openbeken. I get web interface, wifi work, however I need set template so the LED stripe work. Can somebody help?

Here is extracted tuya config from flasher:

Log in, to see the code

Device configuration, as extracted from Tuya: 
- Microphone (TODO) on P23
- LED Cool (Channel 4) on P24
- IR Receiver is on P26
- PWM Frequency 1000
- SPI MISO 17
- SPI MOSI 16
- Control Pin (TODO) on P22
- LED Warm (Channel 5) on P6
Device seems to be using CBU module, which is using BK7231N.
And the Tuya section starts, as usual, at 2023424

Here is backed-up firmware from the board if anybody can help me to get all features working. There are RGB, white, dimming, IR receiver, and button connected to the board.

cijoml · Answer

Well here is what I have achieved for now:

P6 -> PWM/6 - warm white
P20 -> BTN 0/0
P24 -> PWM/4 - cool white
P26 -> IRRecv
Flag3 set to control cool/warm leds.

Pressing Button switch on/off only cool white diodes not warm white diodes - any help?
I still did not get RGB to work. Any help @p.kaczmarek2

p.kaczmarek2 · Answer

RGB control should be possible with this driver: Have you tried it? It should also support CCT (Cool/Warm white) control together with RGB.

cijoml · Answer

Hello can you send me how and where I should configure it?

p.kaczmarek2 · Answer

Is the link I posted not working, or... what's happening? There is a section showing how to configure RGB LEDs, and if you already have two PWM pins for CCT, they should work with it automatically.

cijoml · Answer

There is something wrong with the driver. After applying autoconfig the leds stopped working and now does not work even cold/warm leds with original setup Hopefully it is not destroyed.

p.kaczmarek2 · Answer

I literally used this driver yesterday in RGB (SM16703) + CCT (CW two PWMs) combo and it worked well on Action LSC 3206306:

What is your current device config? Maybe you need to set one of pins to high state? P22 to Always High?

cijoml · Answer

Ah yes 22 always high fixed problem. Seems I have light again

Added after 7 [minutes]:

Now I need to swap blue and green colors since they are swapped.

Added after 47 [minutes]:

This seems to be correct configuration for the RGB.

startDriver SM16703P
SM16703P_Init 40 RBG
startDriver PixelAnim

However there is still problem with WARM white. When I trigger it from main page, LEDs are switched off and dimming not work for warm leds. When I trigger it from App/Status page clicking on/off and dimming I can operate WARM leds with no problem.

Any fix for this behaviour?

>>21370836 Hello, Is there any possibility to get more LED effects? There are tons of effects in WLED project. Can they be somehow included into OpenBeken?

cijoml · Answer

Hello, The strip works like when I address 1 diode 6 diodes start lighting the selected color. Is it such a shitty led stripe that one chip controls all 6 leds and cannot be addressed individually?

p.kaczmarek2 · Answer

I can think about more effects. I'd have to check. But you can always use DDP.

How your strip looks like? I remember seeing such products on market. They have one controller per 6 LEDs or so.

Remember that you can always just buy WS2812 strip and connect it to 5V power supply and it will work with OBK good.

cijoml · Answer

DDP work and I use it now however it utilizes WiFi with small packets which is not OK. If there would be a possibility just to mimic WLED colour effects just inside Beken would be great.
I will make and send photo of the stripe

What is the marking on the IC? Black IC with 8 legs? Is it SM16703?

cijoml · Answer

I cannot see any marking even with magnetizer....

p.kaczmarek2 · Answer

well, it doesn't change the fact that you have one IC controlling 6 classic LEDs. If you want better resolution, buy WS2812 strip, and MAKE SURE to power it from 5V. You don't need another WiFi controller, you can use that one, WS2812 is supported by OBK.

cijoml · Answer

Is there any option for 24V DC LED strip? I live in a clever house and have 24V everywhere so I prefer this voltage so I do not need to use adaptors

p.kaczmarek2 · Answer

That's a very good question. We need to search internet for that.

I've did a brief search and I've found that there are 24V solutions based on, for example, WS2811 chip, but strangely enough, they have LED grouped 6 per pixel, so... so that's exactly what you don't want.

But maybe not all of them...

Search for:


WS2814 DC12V 24V Led Strip Light 4 in 1 Similar SK6812 RGBW Pixels Addressable WS2811 RGBWW RGBCW 5050 3 Pin Lights IP30 65 67

but it also looks like multiple LEDs per chip:
