[Question] Possible to change antenna attitude at runtime?

[lemon-lyman]

Is it possible to update the antenna attitude/orientation at runtime? The information isn't know beforehand so an EEL file doesn't seem like an option.

Yes, send an AntennaProfileEvent from an external application:

from emane.events import EventService
from emane.events import AntennaProfileEvent

# create the event service
service = EventService(('224.1.2.8',45703,'lo'))

# create an antenna profile event to point nem 1 and send to all nems
event = AntennaProfileEvent()
event.append(1,profile=1,azimuth=105.0,elevation=10.0)

# publish the event
service.publish(0,event)

You can verify the above example using emaneevent-dump:

$ emaneevent-dump -i lo
[1615908331.558573] nem: 0 event: 102 len: 24 seq: 1 [AntennaProfile]
 UUID: fb575e7c-af88-4c96-b6ce-4c017ef45ff9
   (1, {'profile': 1, 'azimuth': 105.0, 'elevation': 10.0})

Thanks for the response!

Should I expect these changes to show in the LocationEventInfoTable? After appending your code to my existing CORE script, the LocationEventInfoTable seems to stay as the default values.

I also tried publishing a LocationEvent and it also had no effect on the LocationEventInfoTable

I'm using CORE 7.1, EMANE 1.2.5 in Ubuntu

Try AntennaProfileEventInfoTable.

[lemon-lyman]

AntennaProfileEventInfoTable looks empty

Did you adjust the script to match the interface the emulator is listening for events on?

[lemon-lyman]

It appears to be the same as in the code provided. Here are sections of the core-daemon output

and the emane log on the node

I realized my mistakes.

1. I did not change the device to 'ctrl0' from the 'lo' used in your example
2. I was running the script on host instead of inside the 'nodes' (namespaces) created by CORE

I fixed these two problems and it works now, thanks.
