primary_branch: main
managed_services: sonar

Configuration

You are able to configure it's behavior due 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: sonar's configuration file is based on TOML other than in TOML colon's are also valid (and prettier :) ). Therefore a leading section descriptor is crucial!

[sonar]

Options

enable: true

If set to "false" service will exit on startup, use this option to disable Sonar service.
It will restart on reboot but exiting as long you don't change it to "true".

debug_log: false

If set to "true" service will log every attempt to reach his target.
NOTE: That will highly increase log size, this is intended for debugging purposes only.

persistant_log: false

This option allows you to store a persistant log file "/var/log/sonar.log" if set to "true"
Otherwise it will be only readable by

journalctl -u sonar

and it's not persistant!

target: auto

Your target defines which of your network devices should be target of used 'ping' command
You can use either IP Address or a URL. 'auto' will ping your default gateway (router).
INFO: Avoid using prefixes like https:// or http://

count: 3

How often should be pinged?

interval: 60

Sets interval in seconds, how long it should wait for next connection check.

restart_treshold: 10

The last option is a delay, in seconds, between shutdown WiFi Interface and bring it up again.

That's it. It is'nt 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 losts :)
