MAVLink v2 for Arduino

MAVLink v2 library for Arduino

MAVLink is a lightweight communication protocol for communication between drones (and/or ground systems) and their components.

The underlying MAVLink protocol library automatically gets updated once a month. Correspondence between the library release and MAVLink release can be seen in the versions.yaml file.

Official MAVLink documentation: https://mavlink.io/en/.

Installation

Arduino IDE

Search for "MAVLink" in the Arduino IDE library manager and install the library.

arduino-cli

arduino-cli lib update-index
arduino-cli lib install MAVLink

Usage

#include <MAVLink.h>

void setup() {
  Serial.begin(57600);
}

void loop() {
  // Send HEARTBEAT message to Serial once a second
  mavlink_message_t msg;
  uint8_t buf[MAVLINK_MAX_PACKET_LEN];

  mavlink_msg_heartbeat_pack(1, MAV_COMP_ID_AUTOPILOT1, &msg, MAV_TYPE_QUADROTOR, MAV_AUTOPILOT_GENERIC, MAV_MODE_FLAG_MANUAL_INPUT_ENABLED, 0, MAV_STATE_STANDBY);
  uint16_t len = mavlink_msg_to_send_buffer(buf, &msg);

  Serial.write(buf, len);
  delay(1000);
}

The default used MAVLink dialect is common. You can use another standard MAVLink dialect like this:

#include <MAVLink_ardupilotmega.h>

#include <MAVLink_matrixpilot.h>
