Receives but doesn't send commands

[tichris0]

I was able to configure my WROVER-B device, have it register to Home Assistant and I have no problem receiving data according to the serial console, but for some reason it doesn't actually send anything according to my SDR & Universal Radio Hacker. Given that I can receive, I'm guessing that the issue is with my configuration. My GDO pins re slightly different given that I'm using a slightly different esp32. My understanding is that GDO2 isn't used in this case as the CC1101 chip can only Tx or Rx at any point in time but not both.

My own C app written in Arduino & using the same library works, so I know that the hardware is connected fine and can work as expected.

When I use the remote control I see the following which closely resembles the code I want to send (aka: with some errors):

[I][remote.raw:041]: Received Raw: 413, -653, 388, -662, 387, -659, 365, -677, 367, -319, 733, -650, 385, -657, 384, -659, 380, -316, 745, -642, 401, -295, 729, -681, 382

When I press the button in Home Assistant:

[D][button:010]: 'Garage' Pressed.
[D][sensor:094]: 'transciver': Sending state -78.00000  with 0 decimals of accuracy

Looking at the h file, I think ELECHOUSE_cc1101.setGDO(GDO0, GDO2); is missing for esp32. I never tested that contribution by a user so there may be a bug there. See https://github.com/LSatan/SmartRC-CC1101-Driver-Lib/tree/master

[tichris0]

Hmm I'm not familiar enough with esphome's yaml and how that the whole thing works. Is that something that should be added to the yaml? In theory I can compare my function calls to my C code to know what's missing, but not really familiar with esphome at a Code level.

[dbuezas]

The cc1101.h file.

[tichris0]

Yah I concur with the discussion follow up that you had #25 . I managed to make mine work by changing your code to essentially ignore the USE_ESP32 specific code. Moreover, I've removed all of the ESP32 conditional code and treated it using the regular path and that managed to work. I can send & receive no problem now. Caveat however is that whenever I send something.

Although I can send & receive, sending a stream always results in an immediate crash

[dbuezas]

I just tested an esp32 with the code as is and both sending and receiving work fine for me.

[dbuezas]

I found a way to use a single pin in the esp32, I'll update the repository soon

[dbuezas]

Try this, you only need to connect GDO0 in an esp32 and let me know. If it works well for you I'll check compatibility with esp8266 and maybe add a variant.
