No serial coms with ESP32 with VScode and platformio

hello. I’m struggling to communicate with an ESP32 over serial or to upload the firmware using Ubuntu 22.04 LTS VScode with platformIO installed via VScode’s extensions manager. I have followed the steps links here 99-platformio-udev.rules — PlatformIO v6.1 documentation
with no success.

I can open the port but get no coms in or out. I’ve checked the ESP itself is good and communicated with it using my old Windows laptop.

/dev/ttyS0 for sure is not the right port. S0 is usually the motherboard’s hardware COM port. A regular ESP32 dev board should show up as usually /dev/ttyACM0 or /dev/ttyUSB0.

Double check the avialable devices with CLI → pio device list or ls /dev/tty*.
