   <configure name="MAVLINK_BAUD" value="B57600" />
 </module>

Module configuration options

Configure Options

name: MAVLINK_PORT value: UARTx|UDPx|UsbS
Description: The port device to use for mavlink (default: UART1)
name: MAVLINK_BAUD value: B57600
Description: Baud rate if MAVLINK_PORT is a UART

Module functions

Init Functions

These initialization functions are called once on startup.

mavlink_init()

Event Functions

These event functions are called in each cycle of the module event loop.

mavlink_event()

Periodic Functions

These functions are called periodically at the specified frequency from the module periodic loop.

mavlink_periodic()
- Frequency in Hz: 10
- Autorun: TRUE
  Periodic function automatically starts after init.
mavlink_periodic_telemetry()
- Frequency in Hz: $TELEMETRY_FREQUENCY
- Autorun: TRUE
  Periodic function automatically starts after init.
