Heartbeat (0x0B)

CRSFv3

uint16_t Origin Device Address (Big Endian)
- e.g. Flight Controller is online sends CRSF_ADDRESS_FLIGHT_CONTROLLER 0xC8 / 200

Heartbeat message must always be sent even if telemetry is disabled, which allows the other side of the connection to detect baud rate mismatches.

TODO: Recommended interval? Proposed: Something should be transmitted at least every 1s? Transmit every 500ms if UART is idle?
