Скачать или смотреть Build a Small Reticulum Meshchat Node with Raspberry Pi Zero 2W and RAK 4631 including WiFi Hotspot.

I incorporated a small wifi router into this battery powered node so that it can set up its own wifi / wlan network allowing clients to connect without having to rely on a mains powered router. This makes for an autonomous Reticulum Meshchat node which can be run from a solar charged battery and accessed remotely via wifi.

The following components came from Amazon:

INSTALL AS A SERVICE so that meshchat survives a reboot and does not terminate when ssh session is closed.

sudo nano /etc/systemd/system/reticulum-meshchat.service

Put into the file following 3 statements.
Remember to change username in 4 places as necessary

[Unit]
Description=reticulum-meshchat
After=network.target
StartLimitIntervalSec=0

[Service]
Type=simple
Restart=always
RestartSec=1
User=fotog
Group=fotog
WorkingDirectory=/home/fotog/reticulum-meshchat
ExecStart=/usr/bin/env python /home/fotog/reticulum-meshchat/meshchat.py --headless --host 0.0.0.0

[Install]
WantedBy=multi-user.target


Save file and exit nano

Then do

sudo systemctl status reticulum-meshchat.service

sudo systemctl start reticulum-meshchat.service

sudo systemctl enable reticulum-meshchat.service

sudo systemctl status reticulum-meshchat.service
