We clearly see there's no "DELAY END" sequence here.
This all completelly baffling. It seems that the protocol is actually super-tolerant. Damn, i have no idea why our tx doesn't work. Especially knowing, that tx code in my Arduino bridge DOES work, two people have confirmed that.
There aren't many variables here, really. We are just totally blind... We miss a ve-e-e-e-ry tiny detail.
Unfortunately Glinka has stopped giving me feedbacks, and i have nobody else to test with, I intentionally don't copy everything you're doing because it makes much more sense to try different things.
Also i would suggest to ignore new packet types for now. I think that perhaps they have come to the same conclusion as we did: not reporting actual state sucks; and checksum algo is LOL. They tried to fix this by extending the protocol in backwards compatible manner.
As to unknown bytes [1] and [2]; there definitely should be some capability flags. The AC must have way to indicate which optional features it supports (like H/V swing, LED control, etc). These flags must come with packet type 0, because that's the only data sent regularly. We can try correlating data in those packets to AC models and features they have. But that's low priority; we need to beat tx. We're definitely doin' it wrong(tm); and this wrongness is damn simple.

By the way, those who aren't afraid of Arduinos, can do two-way dump right now:
- Download code from my repo. The sketch you need is in Tools/Simulators/CN_WIRED/bridge
- Uncomment "#define RX2_PIN 3"
- If you want to get raw timings dump, uncomment also "#define DUMP_TIMINGS"
- Wire pin 2 to one line and pin 3 to another. Just in parallel with the wall panel. Yes, you need 5V arduino.
- Flash the sketch in, obviously
- Open serial port monitor in Arduino IDE, or any standalone terminal app on Arduino's COM port
- Watch the logs coming. It will look something like this:
Rx1 80 24 04 50 00 00 00 10 00 OK
Rx2 80 21 00 23 18 08 00 10 A0 OK
Rx1 80 24 04 50 00 00 00 10 00 OK
Rx2 80 21 00 23 18 08 00 10 A0 OK
Rx1 80 24 04 50 00 00 00 10 00 OK
Rx2 80 21 00 23 08 08 00 10 90 OK
Note this is an old dump; newer version will add microsecond timestamp to each packet, so that they can be correlated in time. Timings, if enabled, will look like long string of numbers. Something like:
Rx1 T 2600 1000 300 400 300 400 300 900 ...
(this isn't a real example, i made it up because i only used it to calibrate my own ESP8266 tx routine, and never saved such logs)

I could perhaps be electrical?
Does anyone using a Faikin board on CN_WIRED have an oscilloscope they can use to check Tx?
The board was designed for serial, where the Daikin has internal pull ups, so is driven open drain. But if there is not a pull up, then we need to ensure the 5V is connected to there Faikin board to pull up.

@revk Good thing to check. You may look at schematic of "Daichi" controller in my repo under Hardware/; maybe this will give you some hints. I agree that Tx circuit looks weird; but i rechecked 10 times; Q1 indeed goes to Vcc, and R2 indeed goes to Vio, which looks like +5V. I have no idea how the line is brought down. Perhaps i guessed Q1 wrong; the transistor is unmarked, i simply tried to pick by footprint something that made the most sense.
Maybe that gives you some ideas. Anyways, this circuit does have pullups.

commented on July 18, 2024
Well it also depends if the 5V has been connected to the Faikin. A scope on the Tx would help.

!!! BREAKING NEWS !!! IT WORKS !!!
Glinka65 has found a blown FET on his ESP8266 board. After replacing it everything works like a charm!
https://github.com/Sonic-Amiga/ESP8266-Faikin commit 6e7f267 - this is known working version
@revk If you do everything exactly the same way; the only possible problems are indeed electrical.
I will continue trying to improve the implementation; disabling interrupts on a running OS feels very harsh; But, anyways, we've got known working implementation.

It would help to know if existing testers have 5V connected, and if any have a scope.

I have 5v connected but do not have a scope, unfortunately. I can say that receiving does seem to work (though it does not seem like the mode is necessarily accurately reflected--I have mine running on Auto (not Faikin auto) and it's showing set as cool, but I'm looking at it right now and it's heating.
Happy to connect it to another MQTT server if it's helpful for debugging.

Well, connecting to testmqtt.revk.uk would allow me to see it, but I think we need to confirm the electrical connection somehow. Glad you have the 5V connected, that really should work then.

I assume not, but anything I could do with a standard multimeter to help?

I doubt it, it works some times, so likely signal timing with the 10k pull up not being enough or some such.

Hello everyone! Recent experiment proved that 16ms delay, then 2ms low pulse after the packet is mandatory. Without them the conditioner does not accept the packet.
I am on a short trip for 2 days. See my git log and driver code for more info. It has been verified to work.
Also pay attention to recent commit regarding swing control. Apparently "Daichi" controller , from which i derived the protocol, doesn't get it 100% right.
I will update the documentation when i come back

My code does the 16ms high, 2ms low, at the end, already. Hmm.

And you also have a 10K pullup; totally the same as Daichi board has...
Next week i am leaving for vacation; will be back on 16th of March. I checked ESP32 prices; i can buy a Pico devboard and do some testing with the gear i have (simulator and Arduino bridge). You really seem doing everything correctly; there's a very small thing somewhere.

So, i switched TX back to timer interrupts; and it all works fine. The only thing i had to keep is 16ms high, 2ms low termination sequence.
I guess Daichi does not do this, but still works because it repeats the packet 6 times; and 2500ms start of the repeated packet is somehow taken by the AC as end pulse. Pause between repeats is 16ms; it matches. That's just for info. As i said, my implementation doesn't repeat; it just sends once. Glinka65 says it works great.

Hello guys!
I am here, it's all OK, i am silent because i am busy preparing for the vacation. Leaving for Thailand, will come back on 16th. After this, if you don't fix things by yourself, i'll buy a ESP32 Pico board and try playing with this myself.
