ESP32 + CC1101 - constant restarts (watchdog)

ESPHome

Hi,
I try to setup wmbus integration using component available here: GitHub - SzczepanLeon/esphome-components

Here is my esphome config (without sensors for now, I just want to see telegrams in logs):

I tried many pin configurations, e.g.:

  # mosi_pin: GPIO23 # blue
  # clk_pin:  GPIO14 # purple
  # miso_pin: GPIO19 # green
  # gdo2_pin: GPIO26 # gray
  # gdo0_pin: GPIO25 # yellow
  # cs_pin:   GPIO15 # orange

and

  # mosi_pin: GPIO23 # blue
  # clk_pin:  GPIO18 # purple
  # miso_pin: GPIO19 # green
  # gdo2_pin: GPIO26 # gray
  # gdo0_pin: GPIO25 # yellow
  # cs_pin:   GPIO05 # orange

Yesterday, however, somehow I managed to make it work, but as you can see in logs, I get many issues with WiFi after adding a sensor I faced another issues and I started to play with PIN configurations and lost this working config.

My WiFi is a mix. NASA is 5 Ghz and 2.4 Ghz mix, NASAGuest is 2.4 GHz only, but they both are mesh.
Today I created another WiFi on spare Access Point (nasaiot) which is 2.4 GHz, single device only.

Are you able to point me into some direction? I’m struggling with that since yesterday. I tried also to switch to WeMos D1 Mini, but I got memory allocation exceptions there instead.

My board
Is says ESP-WROOM-32 on it, the FCC ID ends with ESP-32S

I don’t see anything popping on my eyes.
Is your board working normally without cc1101, let’s say running just web server?

3

Yes, everything works fine if I flash it with bare ESP config and CC1101 disconnected (just OTA, API, logger (VERBOSE) and time). It connects to HA and I can use OTA (I tried first without time component and added it later via OTA).

4

Ok, I was thinking known wifi issues with esp32 devs with usb-c.
You could try with full code but cc1101 disconnected for example to filter out wiring issue.

Well, finally I managed to find working pins. I was able to create sensors, everything works well now. Here’s final schema I have:

Component config:

wmbus:
  frequency: 868.950
  mosi_pin: GPIO13  # blue
  clk_pin:  GPIO14  # purple
  miso_pin: GPIO12  # green
  gdo2_pin: GPIO22  # gray
  gdo0_pin: GPIO21  # yellow
  cs_pin:   GPIO15  # orange

board: esp32doit-devkit-v1

Did you find out what was the problem? Some specific pin? Board definition?

7

I think both, board definition and pins, but I can’t tell you exactly what was wrong.
Above combination just worked.
