MAVLink Inspector: Telemetry

MAVLink Inspector turns your Android phone into a pocket telemetry tool for drones, robots and ground stations. Connect to an autopilot, a SITL simulator or a companion computer and see every MAVLink message the moment it arrives.

BUILT FOR DEVELOPERS AND FIELD TEAMS
• Connect over UDP (listen or connect), TCP for SITL, USB OTG serial (SiK, FTDI, CP210x, CDC) or Bluetooth SPP (HC-05)
• Message rate table grouped by system and component, with real Hz, packet loss from sequence numbers and CRC error counts
• Hex view that highlights fields: tap any byte to see which field it belongs to. Supports MAVLink v1, v2 and signed packets
• Live vehicle view: mode, armed state, attitude, battery, GPS and link quality at a glance

FIND PROBLEMS FASTER
• Plot several fields together, such as attitude, vibration and EKF variance
• Pre-arm and STATUSTEXT messages explained in plain language, with suggested fixes
• Parameter viewer: read every parameter, search, compare with a saved .param file and export

WORK AS A TEAM
• Router and bridge: receive telemetry from a SiK radio over USB and forward it as UDP over Wi‑Fi to several laptops at once
• Forward telemetry to an MQTT broker for dashboards and logging
• Record and replay .tlog files in the standard format used by common ground control stations, then share them with your team

FOR GCS AND COMPANION-COMPUTER DEVELOPERS
• Import your own dialect XML to decode custom messages
• Simulator: a virtual vehicle that sends heartbeat, GPS and attitude, so you can test your software without hardware
• Send MAV_CMD and custom messages, with a confirmation screen for every command

SAFETY FIRST
• No pop-up ads, ever. Banner ads are hidden while a link is live
• Dangerous commands (arm, takeoff, motor test) always need two confirmations: a checklist, then a 3-second hold
• The screen stays on while a link is live

FREE AND PRO
Free: UDP and TCP links, the common dialect, the message rate table, hex inspector, pre-arm help, parameter viewer and safe commands.
Pro (one-time purchase, no subscription): USB serial, Bluetooth, custom dialects, .tlog recording and replay, multi-field plots, parameter diff, router and MQTT forwarding, the simulator, and no ads.

COMPATIBILITY
Works with autopilots that speak MAVLink, including ArduPilot and PX4 (copter, plane, VTOL, rover, boat and sub). DJI aircraft do not use MAVLink and are not supported. USB serial needs a phone with USB OTG.

Always follow local regulations and fly safely. MAVLink Inspector is an independent tool and is not affiliated with or endorsed by the ArduPilot, PX4, Dronecode or MAVLink projects.
