Member Function Documentation

◆ frame_rcvd()

void satcat5::udp::TelemetryRx::frame_rcvd ( satcat5::io::LimitedRead &  src)
protectedvirtual

Dispatch calls frame_rcvd(...) for each incoming frame with with a matching net::Type value.

The child class SHOULD read the frame contents from the provided "src" object, which is only valid until the function returns.

To send a reply:

  • Call m_iface->open_reply() to obtain a Writable object. (This also writes out any applicable frame headers.)
  • Write frame contents, then call write_finalize().

The child class MUST override this method.

Implements satcat5::net::Protocol.

◆ telem_packet()

void TelemetryRx::telem_packet ( satcat5::io::LimitedRead &  src)
inherited

The child object MUST call this method for each received message.

This API is also used by net::TelemetryLoopback.
