Notes

ive got 2 heltech v4s connected do i need to use a different node type to get this to work properly?

Your setup looks good, the Meshpoint is receiving packets and everything else is working. The relay error is a permissions issue on /dev/ttyACM1.

Add a udev rule so the meshpoint service user can access the Heltec:

echo 'SUBSYSTEM=="tty", ATTRS{idVendor}=="303a", MODE="0666"' | sudo tee /etc/udev/rules.d/99-meshpoint.rules
sudo udevadm control --reload-rules
sudo udevadm trigger
sudo systemctl restart meshpoint

The 303a vendor ID is Espressif (ESP32-S3). After this the relay transmitter should connect on restart.

[BJHBNade]

ok done now the radio tab is giving an error when turning on the transmit and the error is too quick for me to copy it to actually fix it.
do you know what that message is?
something about chown

[KMX415]

That's likely the sudoers rule missing. The dashboard restarts the service after toggling TX, and without the rule it can't run sudo systemctl restart. Run these:

sudo cp /opt/meshpoint/config/sudoers-meshpoint /etc/sudoers.d/meshpoint
sudo chmod 440 /etc/sudoers.d/meshpoint

Then try toggling transmit again from the Radio tab. If you're still seeing an error, check meshpoint logs right after and paste the output here.

[KMX415]

If the sudoers fix doesn't resolve it: the error is likely a file ownership issue. sudo meshpoint setup writes local.yaml as root, but the service runs as the meshpoint user and can't write to a root-owned file. Run:

sudo chown -R meshpoint:meshpoint /opt/meshpoint/config

Then try toggling transmit from the Radio tab again. The service auto-fixes config ownership on every restart, so this is a one-time thing after running setup.

@BJHBNade all good?

[BJHBNade]

@BJHBNade all good?

i think so it lets me change it now and showed some recieved messages in the message tab looks like im not able to send out still though. ill mess around with teh settings a little

this is what comes up when i try to send nothing goes out it seams

[KMX415]

v0.6.2 adds a udev rule for Espressif USB serial devices (Heltec V3/V4, T-Beam ESP32-S3) that should fix this permission error. Update your Meshpoint and re-run the installer:

\
cd /opt/meshpoint
sudo git pull origin main
sudo bash scripts/install.sh
sudo systemctl restart meshpoint
\\

Let us know if the issue persists after updating.
