Upload a picture of your esp32 connections and explain your wiring, so we could try to debug it
Wiring? Both cards have micro usb port. When i used the CP2102 USB to UART Converter, i used these pins:
CP2102 USB to UART > 5v > VI ESP
CP2102 USB to UART > GND> GND > ESP
CP2102 USB to UART > TX> RX > ESP
CP2102 USB to UART > RX > TX > ESP
and the other way around.

I added a level shifter, since the Bosch Climate 5000i AC use 4V+ and the ESP8266 3.3V. The AC still not recognize the ESP.
Any help?
I’m currently considering whether to buy a Bosch CLC8001i. Has anyone integrated this model into Home Assistant using ESPHome, and does it work?
Or are there other integration options for this model? For example, via Wi-Fi, Home Connect, etc.?
I was also getting timeouts when using pins 1 and 3 and managed to get my Bosch 3000i to work with a ESP32 D1 Mini by using the other RX / TX pair, which in my case are pins 16 and 17.
