| + | ====== Mavlink Routing ====== | ||
| + | |||
| + | Captured data needs to be sent from companion (connected to fc) to gcs. | ||
| + | On the companion there might be also ROS needing access to mavlink messages. | ||
| + | |||
| + | On the gcs side the sent data needs to be handled. QGroundControl can't handle that captured data -> Needs additional software. | ||
| + | |||
| + | Routing of pakets (ros|captured data processing)<*>companion<->fc<->radio<->gcs<*>(qgroundcontrol|captured data processing) | ||
| + | |||
| + | - <*> routing to multiple endpoints | ||
| + | - radio is long distance rfd868 or similar | ||
| + | |||
| + | |||
| + | parallel to the radio connection there might be a long distance wifi connection | ||
| + | |||
| + | (images|captured data processing)<*>companion<->wifi<->gcs<*>(qgroundcontrol?|captured data processing) | ||
| + | |||
| + | open question: route (encapsulated) mavlink pakets also over wifi? | ||
| + | |||
| + | depending on that: combine of images / captured data on gcs side - how? | ||
