Ground station is applicable to the half-duplex serial module, there are 2 working modes: continuous
downloading or request the times of downloading. (It is recommended to use the default continuous
downloading which is combined with Arkbird serial module through the program optimization):
A. Continuous downloading:
Select the “continuous downloading”; the ground station uploads the settings only once, Autopilot is always
in a state of downloading and waiting for the data uploading from the ground station by reserving some blank
time in each period. This can enhance the stability of communication and lessen the impact due to the loss of
request packet. (it is default that 5 packets are downloaded per second, the interval is set as 150ms, when the
parameter “Upload Interval” is invalid)
Blank time: it refers to the empty time reserved at the beginning of every period for the receipt of ground
terminal information.
B. Request times of downloading:
Cancel the “continuous downloading”, the ground station requests the data packet by the upload interval
setup and the Autopilot downloads the request packet after the receipt.
"Circle"
It refers that ground station sends a request packet every period and request to download the designated
plane's information.
"Repeats" and "Interval":
It refers to the number of packets downloaded from the airborne end to ground station within the request
interval.
