# RockBlock Lua Script
|
||
|
|
|
||
|
|
Lua script to send a recieve very basic MAVLink telemetry over a
|
||
|
|
Rockblock SBD satellite modem
|
||
|
|
Requires https://github.com/stephendade/rockblock2mav at the GCS end
|
||
|
|
|
||
|
|
Note that this uses MAVLink1 messaging, due to it's smaller message size compared
|
||
|
|
to MAVLink2.
|
||
|
|
|
||
|
|
Messages will only be send or received if High Latency Mode is enabled.
|
||
|
|
|
||
|
|
Setup:
|
||
|
|
This script requires 1 serial port:
|
||
|
|
- A "Script" port to connect the modem to
|
||
|
|
|
||
|
|
Caveats:
|
||
|
|
- This will *only* send HIGH_LATENCY2 packets via the SBD modem. No heartbeats, no command acknowledgements, no statustexts, no parameters, etc
|
||
|
|
- A single HIGH_LATENCY2 packet will be sent every RCK_PERIOD sec, in addition to receiving
|
||
|
|
a single MAVLink packet from the GCS. This is known as a mailbox check.
|
||
|
|
- Any incoming packets on the first mailbox check will be ignored (as these may be from a long time in the past)
|
||
|
|
- Only 1 command can be sent per mailbox check from the GCS. Any additional commands will overwrite the previous command
|
||
|
|
|
||
|
|
