Source 
pub fn build_aprs_message(
    source: &Ax25Address,
    addressee: &str,
    text: &str,
    message_id: Option<&str>,
    path: &[Ax25Address],
) -> Vec<u8> ⓘ
Expand description

Build a KISS-encoded APRS message packet.

Composes an AX.25 UI frame with the APRS message format: :ADDRESSEE:text{ID

The addressee is padded to exactly 9 characters per the APRS spec. Message text that exceeds MAX_APRS_MESSAGE_TEXT_LEN (67 bytes) is truncated — use build_aprs_message_checked if you want a hard error on overlong input.

Returns wire-ready bytes (FEND-delimited KISS frame).

§Parameters

  • source: The sender’s callsign and SSID.
  • addressee: Destination station callsign (up to 9 chars).
  • text: Message text content.
  • message_id: Optional message sequence number for ack/rej tracking.
  • path: Digipeater path.
