DJI FINDS FIRMWARE BUG CAUSING SPONTAN E OUS S800 SYSTEM FAILURE
Research and testing confirms zero faults with S800 air frame – error found in compass firmware
DJI, one of the world’s leading developers and manufacturers in UAV systems, today announced a
voluntary recall of all WooKong- M GP S compasses purchased after June 15th , 2012. The new
compasses’ firmware contained a bug that, under very specific conditions, could send an erratic signal
causing a spike in power and overall system failure. DJI confirmed both the fault and the bug fi x by flying
four S800s under heavy burden on electric tether for more than 72 hours without failure.
Since learning of the system failures during several S800 flights, DJI spent more than 1 600 man hours in
research and testing to determine the fault and develop a solution for customers. Through the vigorous
research process, DJI engineers not only fixed the bug in the firmware, but also developed multiple new
innovations for the WooKong - M GPS compass.
At this point in time DJI would advise that users of large multi-rotors (S800 size and large r) fitted with
post - June 15
compasses should not fly their multi rotors until their GPS/Compass has been returned for
firmware upgrade .
All customers with WooKong- M GPS compasses purchased after June 15th , 20 12 should contact their
dealer or click http://www.dji- innovations.com/compass/submit_rma/ to get information on returning
their GPS/Compass module for firmware upgrade.
In turn, DJI is also developing a new firmware upgrade for the WooKong - M IMU based on the innovations
developed for the compass bug fix. The IMU firmware upgrade will be released within the next several
weeks and will have superior solutions for the following: better resistance to vibration , less white l ights
and better compass tracking. A further announcement will be made when this firmware enhancement will
We are excited that we not only discovered the fault and developed a fix, but also created a superior
firmware in the process. We look forward to working with all our customers to quickly replace their
a ffected compasses and get everyone back in the air .
