Method Write

ntrip/client.go:202–220

Write sends raw RTCM data to the caster. In NTRIP v2 chunked mode each call is wrapped in a single HTTP chunk. The dump (if any) always receives the raw RTCM bytes, not the chunk framing, so captures remain valid RTCM3 streams.

(p []byte)

// is wrapped in a single HTTP chunk. The dump (if any) always receives the raw
// RTCM bytes, not the chunk framing, so captures remain valid RTCM3 streams.
func (c *Client) Write(p []byte) (int, error) {
	if c.conn == nil {
		return 0, fmt.Errorf("not connected")
	}
	if c.dump != nil {
		_, _ = c.dump.Write(p)
	}
	if c.config.Version == 2 && c.config.Chunked {
		buf := make([]byte, 0, len(p)+16)
		buf = append(buf, fmt.Sprintf("%X\r\n", len(p))...)
		buf = append(buf, p...)
		buf = append(buf, '\r', '\n')
		if _, err := c.conn.Write(buf); err != nil {
			return 0, err
		}
		return len(p), nil
	}
	return c.conn.Write(p)
