Establishing a MAVLINK connection to VOXL 2

[svempati]

Hi everyone, I am trying to read mavlink messages like the pressure and altitude from the VOXL 2 sensors using python. I wanted to make sure that the udpin to the mavlink connection is correct? Would setting the udpin to localhost work or is there another udpin address to use for connecting the VOXL 2 board to the mavlink server? I set the port number to 14557 based on the first diagram in this page: (https://docs.modalai.com/mavlink/).

# MAVLINK Common Message Set: https://mavlink.io/en/messages/common.html
from pymavlink import mavutil

the_connection = mavutil.mavlink_connection('udpin:localhost:14557')

the_connection.wait_heartbeat()
print("Heartbeat from system (system %u component %u)" % (the_connection.target_system, the_connection.target_component))

while True:
    try:
        # local xyz position
        msg_pos = the_connection.recv_match(type='LOCAL_POSITION_NED', blocking=True)
        print(msg_pos.x, msg_pos.y, msg_pos.z)

        # altitude
        msg_altitude = the_connection.recv_match(type='ALTITUDE', blocking=True)
        print(msg_altitude.altitude_local, msg_altitude.altitude_relative)

        # pressure
        msg_pressure = the_connection.recv_match(type='SCALED_PRESSURE', blocking=True)
        print(msg_pressure.press_abs)

    except KeyboardInterrupt:
        print('Terminating mavlink...')
        break
