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
Define Options
- name:
MAV_AUTOPILOT_ID
value: MAV_AUTOPILOT_PPZ|MAV_AUTOPILOT_ARDUPILOTMEGA
Description: Some MAVLink GCS/Devices require specific ID's to work. Default is to identify as MAV_AUTOPILOT_PPZ.
Module functions
Init Functions
These initialization functions are called once on startup.
Event Functions
These event functions are called in each cycle of the module event loop.
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()
- Running at maximum module frequency.
- Autorun: TRUE
Periodic function automatically starts after init.
