Unable to Communicate with Node Via Meshtastic CLI

[amaxwellnsa1]

I hope I'm posting in the correct location. Having some trouble using the python CLI on a linux machine.

Linux Distro: Void Linux

uname -a
Linux HOSTNAME 6.6.58_1 #1 SMP PREEMPT_DYNAMIC Wed Oct 23 16:39:51 UTC 2024 x86_64 GNU/Linux

I've never had issues with this on Debian based distro's. Any who, esptool is able to communicate and successfully flashes firmware just fine via usb/serial "/dev/ttyACM0"

However meshtastic refuses to connect to the USB serial connection. I've tried various methods to communicate with the node. It does seem to work via hostname/IP , but not via serial.

meshtastic -s /dev/ttyACM0 --info --debug

exact same when I run "meshtastic -s /dev/ttyACM0 --info"

however when I run: "meshtastic --noproto"
I seem to get output:

meshtastic --noproto
WARNING file:mesh_interface.py _sendToRadio line:959 Not sending packet because protocol use is disabled by noProto
Connected to radio
DEBUG | ??:??:?? 1041 [Power] Battery: usbPower=1, isCharging=1, batMv=4208, batPct=100

it does seem to be a little less busy than I've seen on these devices before, But I'm not certain if that's just because there's not much network activity at the moment.

Here's the output of "meshtastic --support"

If having issues with meshtastic cli or python library
or wish to make feature requests, visit:
https://github.com/meshtastic/python/issues
When adding an issue, be sure to include the following info:
 System: Linux
   Platform: Linux-6.6.58_1-x86_64-with-glibc2.39
   Release: 6.6.58_1
   Machine: x86_64
   Encoding (stdin): utf-8
   Encoding (stdout): utf-8
 meshtastic: v2.5.4
 Executable: /home/user/.local/bin/meshtastic
 Python: 3.12.7 CPython GCC 13.2.0

and this behavior doesn't seem to change between the two nodes I've been able to test with:

lilygo tlora v2.1-1.6
heltec v3

The only real difference I can see between this and my raspberry pi is the python version: (pi is 3.11.2) and the CPython GCC (pi's is 12.2.0)

I'm hoping someone has some direction for me. My apologies if I'm not in the right place here. I just figured posting an "issue" would place blame on the code here, which I'm really not confident is the problem here. Being new to this distribution (and loving it so far), I'm sure it's possible Ive messed something up here.

Thank you in advanced.

I see that I was using -s instead of --port, here's a corrected command and output:

meshtastic --port /dev/ttyACM0 --info --debug

It looks like the serial port never gets an awknlowldgement from the device, which can mean one of two things:

1. You are in the dialout group, so it's a permissions issue (https://meshtastic.org/docs/software/python/cli/usage/#permission-denied-devttyusb0 ) , or
2. The serial output of the device is not enabled.

From the error messages you never got actually connected.

Check @kop316 suggestion.

An other simple one is the connecting cable. Try to change the USB cable. did you use the same cable?

Also try to run as root.

Then you can check what you see with "lsusb" commands.

Let us know how it goes.
