Expert ~ OSD MAVLink message types

Recommended SRx parameters for MAVlink telemetry (also see FC Parameters) are:

• SR1_EXT_STAT: (voltage, ampere, satfix, sats) 2Hz
• SR1_EXTRA1: (roll, pitch) 10Hz
• SR1_EXTRA2: (speed) 5Hz
• SR1_POSITION: (GPS heading, alt, lat, long) 5Hz

Depending on the serial port used, parameters may also be named SR0_xxx or SR2_xxx. Make sure that the flight control sends out the above telemetry data sets on the appropriate serial port.

The integrated wifibroadcast_osd supports the following Mavlink message types:

MAVLINK_MSG_ID_GPS_RAW_INT:

• fix = mavlink_msg_gps_raw_int_get_fix_type
• sats = mavlink_msg_gps_raw_int_get_satellites_visible

MAVLINK_MSG_ID_GLOBAL_POSITION_INT:

• heading = mavlink_msg_global_position_int_get_hdg
• altitude = mavlink_msg_global_position_int_get_relative_alt
• latitude = mavlink_msg_global_position_int_get_lat
• longitude = mavlink_msg_global_position_int_get_lon

MAVLINK_MSG_ID_ATTITUDE:

• roll = mavlink_msg_attitude_get_roll
• pitch = mavlink_msg_attitude_get_pitch

MAVLINK_MSG_ID_SYS_STATUS:

• voltage = mavlink_msg_sys_status_get_voltage_battery
• ampere = mavlink_msg_sys_status_get_current_battery

MAVLINK_MSG_ID_VFR_HUD:

• speed = mavlink_msg_vfr_hud_get_groundspeed
