APRS-IS ASGI protocol server. Allows receiving messages from, and sending messages to, the APRS network.

Incoming frames are scoped by their callsign.

The scope and application instance will be made when a frame with that callsign is received after process start, and will be lost either when the callsign has been inactive for some time and it is garbage-collected or when the current process ends.

If you want to manage long-lasting, per-callsign state, it's recommended you use a database or some kind of session store.

The scope contains:

• type: aprs
• callsign: APRS callsign, including SSID suffix if nonzero (e.g. K3AEA-1).

An incoming frame. Might be targeted at the callsign of the APRS server, or if the server is configured for full-feed or location-based, to any callsign.

Frequensgi will try to decode the frame as much as it can and give you high-level values, but the raw frame will always be included in case there is custom packing logic involved.

Keys:

• type: asgi.frame
• frame: Byte string of the entire received frame.
• ``from

An outgoing frame. Will be sent from the server's configured callsign out into the APRS-IS system.

Keys:

• type: asgi.send_frame
• frame: Byte string of the frame to send. If provided, no other keys are used.
• ``from
