Can't connect via TCP
Tested at Linux and MacOS

TCP via meshcore-proxy

Code:

from meshcore import MeshCore, EventType

async def main():
    meshcore = await MeshCore.create_tcp("10.41.0.14", 5000, auto_reconnect=True, debug=True)
    if not meshcore:
        return

Log:

DEBUG:meshcore:connection established
INFO:meshcore:TCP Connection started

DEBUG:meshcore:data received

I launch meshcore-proxy via --log-events

Thank's for the report
I'm not familiar with meshcore-proxy yet (just discovered it)
How does TCP cx work for you with tcp companions, or with a serial port forwarder (such as socat) ?

[SantaSpeen]

I didn't quite understand your question (Not very good at the language)
I can say that MeshCore app works perfectly with meshcore-proxy

Is there any other way to connect a companion via TCP even if it doesn't support Wi-Fi?

[fdlamotte]

I tried with a wifi companion and it worked ok

But I also tried with an USB companion with a port redirection using socat and it did not work. So I assume there is some issue that arises when using a proxy

I'm not sure of my socat command though, here is what I used (not been able to find the commands I used in the past and were working, will take some time to dig more on that point) :

socat tcp-l:5000,reuseaddr,fork /dev/ttyACM0,b115200,raw,echo=0

[SantaSpeen]

I don't have direct access to USB in my configuration, so it's difficult to verify
