Issues with mmwave GPIO pin

I am currently having issues with the mmwave GPIO pin on the ESP32-S2. Sometimes when the pin i high, it isn't detected by the ESP. I checked the connection, which seems to be okay. Maybe the issue is the internal pulldown.

Anyways I was searching for other solutions. I found out that the mmwave sensor is also sending the value over UART so i tried to write a custom binary sensor component for that, but haven't gotten far due to my horrible C skills.

But i now also found that someone else might have already done the work: esphome/esphome#4203

We could evaluate this solution and maybe save a gpio pin, which can then be used for something else, like audio output.

Does the any other ESP work for you?

@MeisterGig any update? Otherwise I would close this issue.

I haven't tried it anymore.
