Both in a way. Bus Pirate, both the hardware and the software, is completely open source. It's not the same version, things are different, but it's largely inspired by it.
However, the entire implementation is new, it's not a copy
Nothing there adresses the problem. No one should have to tell you why it's wrong to use someone elses (reconized earned) name, or how "prefixed by esp32" does not change anything. Do what you want but don't delude yourself that you're in the right.
I generally agree, and also do in this particular case, but one could argue that bus pirate is so successful that it turned into a genericide (Kleenex, Hoover, Thermos, Zipper, …).
Not to mention, what if the original bus pirate developers wanted to support esp32? It's just wrong all around.
Tomorrow I'm going to make one based on pi pico, and I want to sell them. But I have 2 problems:
1 I suck at embedded code and electronics design so my product barely works. It isn't reliable, accurate, or safe for the device under test.
2 there are already a ton of cheap mcu logic analyser projects and products...
How can I get mine to be popular instantly despite those problems? I'll just use someone else's popular recognized and well-regarded name that they earned the hard way. I'll call it the "Flipper Bus Pirate". This is totally ok because "Flipper Bus Pirate" is not "Bus Pirate" and it's also not "Flipper Zero". I don't understand why you are yelling at me.
Hm, maybe this will finally let me network my IR-controlled AC units. There are a bunch of ESP/IR projects, but for some reason I haven't gotten them to work (pretty sure it's a problem with my hand-assembled hardware, in fairness)
I recently converted all of my (5 in 3 buildings) mini splits on my property to be controlled by Home Assistant. It took some research but all I ultimately needed was:
this USB ESP32 module which works out of the box on Midea-produced units (Carrier, Electrolux, Pioneer). I have a few units that are other generic brands which apparently are rebranded "Aux" brand units, so I re-flashed the ESP32 board above to work with Aux units by doing `brew install esphome` and then `esphome run auxminisplit.yaml --device /dev/tty.usbserial-210` where auxminisplit.yaml is https://gist.github.com/jasongill/35a13e458b6d109ca2bbefeab4...
That worked perfectly for me and should cover like 90% of all minisplits (Midea and Aux make a ton of brands units), let me know if that works for you.

Certainly could be the case. I've spent more time than I want to admit chasing down what was ultimately a loose wire.
For what it's worth, you can get a cheap ESP32 module and basic IR sensor modules for a few bucks on amazon [0]. As long as you have a basic USB <-> TLL/Serial adapter, you should be able to install ESPHome on that. The module that's on that particular board does not have a ton of room so keep the ESPHome config simple and to the point.
It's a few dozen lines of yaml total to get a basic IR signal decode/dump tool: [1]
Thanks; $17 is much cheaper than the time it would take me to fix mine:) And limited space is fine, for my use case I just need to turn MQTT or HTTP POSTs into like three different signals.
If it can run at the right speed or frequency or whatever, I'm perfectly happy for it to work purely by recording and replaying signals that I give it with my remote.
What is it about AC that makes it impossible to control?
I live in New Zealand where we pretend that it’s never particularly cold or particularly hot. This might be a factor in how sloppy all the installs seem to be.
Too bad ir doesn't do CAN-bus, either using ESP32's integrated TWAI controller and a hardware interface with a transciever or a MCP2515 controller. The M5 has a CAN-bus transciever¹. Thay way it would be really useful on cars and more recent e-bikes.
It might have been poorly worded, English is not my native language, but there was nothing mean in my message. To put it more clearly, I meant: fork it and make a pull request to help me implement it.
Don't worry, at least I didn't think it was mean or anything.
The "joke" was that implementing bitbanged I3C on an ESP32 (!) sounds absurd. Like doing raytracing on C64. (Of course some crazy folks have done it though)

See here for a very large database of IR signals that works with the firmware.

Nothing; there is something about my AC and the badly hand-assembled ESP8266 and IR transmitter I made that doesn't work.

I recently found a remote that doesn't to the 30kHz modulation-- good luck to me controlling that with anything.
