This means you will not be able to control motors, but all other subsystems including GPS position lock are working. Disarmed, GPS Lock: Similar to above, but your vehicle is disarmed. In this mode, vehicle can perform guided missions. Armed, GPS Lock: Indicates vehicle has been armed and has a valid position lock from a GPS unit. This means you will not be able to control motors, but all other subsystems are working. Disarmed, No GPS Lock: Similar to above, but your vehicle is disarmed. Vehicle cannot perform guided missions in this mode. When vehicle is armed, PX4 will unlock control of the motors, allowing you to fly your drone.Īs always, exercise caution when arming, as large propellers can be dangerous at high revolutions. Armed, No GPS Lock: Indicates vehicle has been armed and has no position lock from a GPS unit. In the event of an error (blinking red), or if the vehicle can't achieve GPS lock (change from blue to green),Ĭheck for more detailed status information in QGroundControl including calibration status,Īnd errors messages reported by the Preflight Checks (Internal).Īlso check that the GPS module is properly attached, Pixhawk is reading your GPS properly, and that the GPS is sending a proper GPS position. A valid global position estimate is required to takeoff! It is possible to have a GPS lock (Green LED) and still not be able to arm the vehicle because PX4 has not yet passed preflight checks. The image below shows the relationship between LED and vehicle status. FMUv4 does not have one on board, and typically uses an LED mounted on the GPS). This is typically a superbright I2C peripheral, which may or may not be mounted on the flight controller board (i.e. The RGB UI LED indicates the current readiness for flight status of the vehicle. They indicate power, bootloader mode and activity, and errors. The Status LEDs provide status for the PX4IO and FMU SoC.The UI LED provides user-facing status information related to readiness for flight.Pixhawk-series flight controllers use LEDs to indicate the current status of the vehicle.
