A small Keepalive daemon for MainsailOS (or any other Raspberry Pi OS based Image).
git clone https://github.com/mainsail-crew/sonar.git
cd ~/sonar
make config
sudo make install
cd ~/sonar
make uninstall
Simply add
[update_manager sonar]
type: git_repo
path: ~/sonar
origin: https://github.com/mainsail-crew/sonar.git
primary_branch: main
managed_services: sonar
install_script: tools/install.sh
to your moonraker.conf
You can configure its behavior using a file in "~/printer_data/config/sonar.conf". But you don't have to. Defaults are hardcoded and Sonar will run without any configuration.
Hint: The Sonar's configuration file syntax is based on TOML other than in TOML colons are also valid (and prettier). Therefore, a leading section descriptor is crucial!
[sonar]
enable: true
This setting is only evaluated at boot or when the service restarts. Set to "false" to prevent Sonar from starting. It won't run until you change it back to "true" and reboot or restart the service.
debug_log: false
If set to "true" service will log every attempt to reach its target. NOTE: That will highly increase log size, this is intended for debugging purposes only.
persistent_log: false
This option allows you to store a persistent log file "/var/log/sonar.log".
Otherwise, it will be only readable by journalctl -u sonar and it's not
persistent!
target: auto
Defines the ping target. Use an IP address, hostname, or 'auto' to automatically ping your default gateway (router).
count: 3
Number of pings per connection check. Multiple pings help avoid false positives from brief network hiccups. A check is considered failed only if all pings fail.
interval: 60
Sets interval in seconds, how long it should wait for next connection check.
restart_threshold: 10
Delay in seconds before attempting WiFi restart after connection loss
That's it. It isn't the best method to keep your WiFi up and running, but it is the easiest solution without changing firmware files or similar.
I hope you will find sonar useful, and it blows away your connection lost :)
