Hi, I haven’t been able to connect to my esp32 on my linux machine, platformio doesn’t seem to be able to see the board (works fine with a nano or on windows).
It’s equiped with a ch9102x so I installed this drivers:
I get this from dmesg:
[ 6496.609147] usb 1-1.2: new full-speed USB device number 10 using xhci_hcd
[ 6496.717948] usb 1-1.2: New USB device found, idVendor=1a86, idProduct=55d4, bcdDevice= 4.43

[ 6496.722708] usb_ch343 1-1.2:1.0: ttyCH343USB0: usb to uart device
If I’m correct it’s mounted to /dev/ttyCH343USB0 but why isn’t platformio able to see it ?
Is there a way to correct this, or force it to mount to /dev/ttyUSB0 ?
Really sorry to ask this, I know it’s probably trivial I tried some solutions I found online but none of then did work so I must be doing something wrong, thanks in advance.
Getting permission refused when doing “/dev/ttyCH343USB0” (i’m in the dialout group and I also tried adding myself to root and tty just in case).
Can’t get the arduino IDE to work either, it returns some permission error when trying to use the serial monitor.
What’s weird is that I can see the port with arduino IDE but not through platformio → devices, might it be looking only for ttyUSBX ?
After doing a you have to at least log out and log in again, or reboot the computer. See the lower part of Redirecting....
PlatformIO uses pyserial to identify the serial ports, which may have some filtering (?), Arduino IDE is Java based and may use different logic. In any case setting upload_port = .. explicitly should work around that problem.
