December 2022 update:
* the IR blaster is now working (firmware 1.15.x , i tested mine on 1.15.226)
* this device is Model S08 / PCB: S06-CBU-V1.2
* all the pins needed for flashing are easily accessible on the board (TX1,RX1,GND,3.3v and CEN for reset)
* After flashings set pins as follows and restart the device! (IR pins are not changed at real-time)

Pin Description

7 IRSend

8 IRRecv

24 wifiLed

* Testing the IRRecv: go to the webapp log and shot some coded for external remote, you should see something like that:

I haven't seen a BK7231N IR remote control before. Where did you buy it?
CBU module information:

Pin number	Symbol	I/O type	Function
1	P14	I/O	Common GPIO, which can be reused as SPI_SCK (Correspond to Pin 11 of the IC)
2	P16	I/O	Common GPIO, which can be reused as SPI_MOSI (Correspond to Pin 12 of the IC)
3	P20	I/O	Common GPIO (Correspond to Pin 20 of the IC)
4	P22	I/O	Common GPIO (Correspond to Pin 18 of the IC)
5	ADC	I/O	ADC, which corresponds to P23 on the internal IC (Correspond to Pin 17 of the IC)
6	RX2	I/O	UART_RX2, which corresponds to P1 on the internal IC. (Correspond to Pin 28 of the IC)
7	TX2	I/O	UART_TX2, which is used for outputting logs and corresponds to P0 of the internal IC (Correspond to Pin 29 of the IC)
8	P8	I/O	Support hardware PWM (Correspond to Pin 24 of the IC)
9	P7	I/O	Support hardware PWM (Correspond to Pin 23 of the IC)
10	P6	I/O	Support hardware PWM (Correspond to Pin 22 of the IC)
11	P26	I/O	Support hardware PWM (Correspond to Pin 15 of the IC)
12	P24	I/O	Support hardware PWM (Correspond to Pin 16 of the IC)
13	GND	P	Power supply reference ground
14	3V3	P	Power supply 3V3
15	TX1	I/O	UART_TX1, which is used for transmitting user data and corresponds to Pin 27 of the IC. For the MCU solution, please refer to CBx Module.
16	RX1	I/O	UART_RX1, which is used for receiving user data and corresponds to Pin 26 of the IC. For the MCU solution, please refer to CBx Module.
17	P28	I/O	Common GPIO (Correspond to Pin 10 of the IC)
18	CEN	I/O	Reset pin, low active (internally pulled high), compatible with other modules (Correspond to Pin 21 of the IC)

complete datasheet - https://developer.tuya.com/en/docs/iot/cbuipex-module-datasheet?id=Kaedsyurckrhu
I bought from Aliexpress - https://www.aliexpress.com/item/4000764652478.html
I do plan to use TX1, RX1 for flashing. the pins are easily accessible on the board.

does the firmware support such cases of IR?

I stayed on the stock exchange by mistake, I thought it was something else , for PLN 10 I bought such a miracle:
https://www.amazon.pl/SwitchBot-Smart-pilot-zdalny-sterowania/dp/B07TTH5TMW
All in all, I had a little fun and put it back in the wardrobe because I don't have so many devices with IR remotes in one room and those for which I don't have a remote are not on the list of predefined devices, so it doesn't give me anything anyway.
I will see, maybe someday I will find some use for it.
It looks a bit different inside

There should be no problems with IR soon, just wait.
I will try to order such a device for testing, if I find it somewhere with cheap shipping to Poland.
Can you also do a flash dump for tuya-cloudcutter?

I can also see it has a SH4 433MHz radio module, do anyone know here how it works? Is it just like with simple wall switches, where RF chip just outputs digital 1 or 0 signals on button inputs?
Quote:

SH4 is a low-power embedded Sub-G 433M that Tuya has developed. It consists of a highly integrated RF transceiver chip (CMTOV30-EQR) and a few peripherals. SH4 needs to control transmitting and receiving with the MCU. On the basis of this, you can develop the embedded Sub-G communication products as needed.

Yes, let's get IR working! I will also buy that one.

But wait... can't we just get any IR receiver module (even one from old CRT TV) and use that for testing? I have tons of them.

I think you can just connect any IR receiver and IR transmitter from any remote to test it out with beken chip similar to esp

@omelchuk890 you are seeing correct, although it is a preliminary development version. Please wait few days.
@ferbulous I'm on it. Here are some random photos from IR testing, my IR parts collection, comparison with Arduino, preparation of WB2S. Stay tuned for more!

@ferbulous we're working on it, but it's T only so far.
Here is a LED strip driver that didn't have IR receiver at first but I managed to solder one to it:

EDIT: I see that my camera broke the effect. You should see the strip dimming going gradually up. I can increase the brightness of the strip via remote, but my camera also has auto-brightness and on video it looks bad.

Development test ONLY script, do not use because it sets PWM directly (it ignores LED driver with Enable function):

Tested on firmware 1.14.42 - reception is working, data in MQTT is leaving.
How do I send a transfer command via MQTT?

@p.kaczmarek2
You are simply a treasure of knowledge, patience and enthusiasm!!!

P.S. I have noticed device freezes...
only a power reboot helps.
And the IR receiver sends incomprehensible data to the controller even if it is completely closed. I watched the oscilloscope at its output.
Spoiler:

The other receiver does the same thing.
Spoiler:

But I just need to read the data and then I can turn off reception.

Thank you.

Yesterday we had to increase the stack size slightly to prevent potential, exactly, freezes, that happened to us in multiple places. Today I also added a MQTT deduper, which prevents things like "led_enableAll" being send multiple times per second due to user holding a remote button to turn up gradually the brightness.

More optimization coming soon.

The "unknown" IR kind of packets are hidden now, they're just noise.

This looks very promising! I have the same IR blaster as yarix2 (the s06-CBU-v1.2 board) and successfully flashed it with OpenBK7231N. Does anyone know what settings you should use for the IRsend and IRRecv pins? I tried to test a (wrong) pin but the device almost bricked. It's up and running now but I damaged the RX1 solder pad (I know, stupid me) so I can now only do OTA updates so I'm a bit worried of making a mistake and not being able to re-flash the device again.

Edit: If I'm not mistaken IRRecv seems to be on Pin 8 (according to my multimeter). Unfortunately I seem to have killed the device while reverse engineering the traces so I can't test it myself at the moment.

Hello @avdm . The N platform requires a timer adjust which has not been done yet, but @btsimonh has just received his N IR receiver today, sooo I hope this will be resolved soon. Please wait several days, ok? In a meantime, check which pin connects where.

Also don't worry about bricking the device. IR driver is started only in normal mode, and safe mode is started if device fails to boot correctly for 30 seconds 5 time in the row. No matter what happens with IR, you should always be able to get back into the safe mode and use it to change back the configuration (pins config) back to safe one.

Thank you for the update, I appreciate it! And you are absolutely right. After some power resets the device came back to life. I've ordered 2 extra (Got a great deal: 2 for less than €13) so I can safely use the unit I already have as a test device.If there is anything I can test, please let me know. In the mean time I"ll wait patiently.

About the pins:
A quick test with my multimeter seems to show the following:

Pin	Symbol	I/O type	Function	Possible connection
8	P8	I/O	Support hardware PWM (Correspond to Pin 24 of the IC)	IRRecv
12	P24	I/O	Support hardware PWM (Correspond to Pin 16 of the IC)	IRSend and/or status led

I think that @btsimonh got IR working on N today. It was just a little fix related to timer. It should be possible to receiver IR on both T and N now. Only MQTT rate improvements are pending. If you spam a lot of IR MQTT, then you might get a MQTT disconnect.

IRreceive is working! I tested it with multiple remotes and seems to work great. The receive pin is Pin 8. Does anyone know if the transmitter also works? I haven't figured out how to use that successfully. I've tried to sending the following command in the log terminal like this but it didn't seem to do anything (no IR led flashes detected with my phone camera).
Code: text Expand Select all Copy to clipboard
IRsend {"Protocol":"PANASONIC","Bits":48,"Data":0x100BCBD}

Maybe the formatting is of as it seems different then the MQTT formatting. Any guidance would be much appreciated.

You must enable IR driver first, "startDriver IR". Futhermore, I am not sure because I am not at home right now, in some cases you might get incorrect "command not found" messages while it was executed (I am not sure, it is being addressed these days and should be fixed next week).

EDIT: Wait, you typed whole C code into the console? That is not right.

You should rather try:
Code: text Expand Select all Copy to clipboard
IRSend NEC-1-1A-0

Syntax is: PROT-ADDR-CMD-REP, protocol-address-command-repetitions

@p.kaczmarek2
is it possible to add an output to the transmitter in an inverted form? as on a relay or led.
I always have this, when choosing "output to IR", this is how the output stage is built, common emitter circuit

I have transistors, output, control the LEDs as a relay output or led - the high level turns on the ir.
