Windows - Cannot connect to seeed-xiao-s3 using serial port after upgrade from v2.6.0 to v2.6.1

[krzotr]

I have upgraded the library to 2.6.1 using pip install meshtastic==2.6.1 and cannot connect to my seeed-xiao-s3 using the serial port. I have tested my other device - tbeam is working fine with 2.6.1.

My platform:

• Windows 11 x64
• meshtastic --version: 2.6.1
• device: seeed-xiao-s3
• firmwareVersion: 2.6.4.b89355f

test.py code:

import logging

logging.basicConfig(
    level=logging.DEBUG,
    format="%(levelname)s file:%(filename)s %(funcName)s line:%(lineno)s %(message)s",
)

import meshtastic.serial_interface

iface = meshtastic.serial_interface.SerialInterface()
print(iface.getMyNodeInfo())

Running my code

pip install meshtastic==2.6.1
python .\test.py

Also --info does not work

Reverting to 2.6.0 pip install meshtastic==2.6.0 - everything is fine - can connect to seeed-xiao-s3:

I'm seeing something similar with T3S3 E-Paper. Reverting bc1664d seems to fix it for me.

Had same issue with 2.6.1, downgrading to 2.6.0 worked instantly. I was connecting to a SenseCAP Card Tracker T1000-E using serial (com) on windows.

Interesting, Tbeam supreme isn't working, but my heltec wireless stick v3 is fine.

yeah, I'm thinking that patch improved things for some nodes but broke it for the rest. I guess the simplest solution might be to hide that behavior behind a flag. There's another issue where folks were having issues even with the existing non-Windows equivalent, and I don't know if we can detect which setup is needed very easily.

I've always used the --wait-to-disconnect [SECONDS] argument to keep the port open when using devices which reset on DTR. It's not super elegant, but it does work.
