8.5 Resetting default camera settings
In case of unwanted configuration changes, the camera can be re-configured to
a suitable state. Please refer to your camera user manual in the download section
of our website for the procedure.
8.6 Improving radio signal communication
You may occasionally lose the data connection between eMotion and your eBee
while in the field. Whether there is a loss in uplink or downlink communication,
the drone will continue flying along its Flight Plan and should re-establish the
connection as it flies closer to the base station or changes direction.
If the drone stops receiving messages from eMotion (uplink direction) for more
than 30 s you will see a ‘Data uplink lost’ In-flight warning appear in eMotion. If for
safety reasons you would like the eBee to automatically return to the Home way-
point when this warning appears, select the corresponding option in the Flight
Parameters tab⁶¹.
If there are no more messages received by eMotion from the drone (downlink di-
rection), a ‘Data downlink lost’ message will appear in eMotion. If there is still an
active uplink connection you may still command yourdrone to return to the Home
waypoint using the Control Bar.
Data connection range can be effected by many external factors such as antenna
height, terrain and obstacles or radio interference. We recommend the following
tips to improve the range of your connection in the field:
1. Place the USB ground modem as high as possible (for example, on top of a
car, ladder or nearby building). A height of at least 2 m is recommended.
2. Ensure that the USB ground modem’s antenna is pointing straight up.
3. Disable any 2.4 GHz-based communication devices (or put them into ‘Air-
plane mode’) in the vicinity of the USB ground modem. This includes all
