RotCtl delay needed

[jwcutler]

I had to slow down the update rate for RotCtl for proper rotator position queries. It might be useful to make the sleep duration an argument. Thanks!

Hi,

thx for reporting this. Have you any insight on what's the bottleneck here? Is it rotctld itself? Are you getting an error when polling too fast?

Hi, I am using SPID RAS rotator and I believe I'm having the same issue. I'd need to slow down the polling of position. I've tried querying position via rotctl manually during an observation and sometimes I even got an error. The response of rotctl is noticeably slow (almost a second) when idle. God knows what's happening in there when the observation is running. I've tried setting up rust, but I could not get it running. I'll give it a shot some other day.

@AdamKrovina: thx for the infos, I'll try to fix this within the next days.
