Control link heartbeat mechanism #30
Description
As UDP protocol doesn't know link is broken by protocol it self. So we need a heart beat mechanism to know if the link is lost.
If control link is lost, we have to to some emergency actions.
Suggested way:
a) heart beat: is there any status check request??? RC status? location???
b) normal commands should be considered as a heart beat to reduce bandwidth
c) C/S model is used, and air unit is server side, app (mobile, ground station) is client.
