• Mojolicious
• SQLite (and frequency database in data directory)
• Modules/Plugins
  • DBIx::Connector to access SQLite

Note

In its current state rtl-fm_scanner is not intended for general use. In fact it may never reach that point.

rtl_fm-scanner's Issues

Squelch Capability

Allow client to override default squelch setting used by rtl_fm.

Configuration Support (Frontend)

Create interface to allow user change configuration settings.

Configuration File Support (Backend)

Implement system to persist configuration. See leaderboard for sample implementation.

Store Scanned Frequencies

Store scanned frequencies in database.

Ping Response That Contains Status

Change the keepalive function such that server does check of connectivity or other checks (scanning, etc) and reports back to client in ping response. This could be be used to notify user of issues.

Also, lack of response to the ping should result in re-open of socket or notification to user.

View/Change Frequency Settings

Update frequency list page to indicate of there is manual or auto pass assigned to channel. Allow user to change settings for manual/auto pass.

Keepalive Capability

Although there may be possibility to use Websocket keep alive function create one at application level. Adjust Websocket time out as appropriate.

Update Dongle Error Handling

Not all errors from rtl_fm are checked. See code for examples.

Mutiple Dongle Support

Split up scanning across multiple dongles.
