    A new firmware update (V2.5) is now available for A2. Please visit http://www.dji.com/product/a2/download to download the latest assistant software and update your A2.


    All-in-One Firmware version updated to: V2.5

    Major Updates:


    l Added support for Zenmuse gimbal channel control, allowing users to control the aircraft and gimbal using a single remote.

    l Modified Home Lock control mode that creates a no-fly zone of 10m radius around Home Point. This is to prevent the pilot from becoming disorientated.

    l Added data recording for GNSS coordinates and aircraft attitude. Use the latest iOSD Data Viewer to export this data for post-processing.

    l Fixed PC ground station display and waypoint related issues.

    l Changed the default action for the first level voltage alarm from a flashing light to RTH.

    l Fixed heading problem during initialization when using the GPS-COMP-PRO-PLUS module.

    l Display GPS SNR Health and SNR Fluctuation status in the DJI Assistant and iPad Ground Station.

    User Manual

    l Added information on connecting the gimbal to the CAN2 port and relevant channel mapping.

    l Added description of GPS SNR Health and SNR Fluctuation.
