LOOP packet requests?

From build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

LOOP packet requests?

Post by prodata »

Anyone know how many LOOP packets CMX requests at a time? I thought it might be just one but seeing something that suggesting it might be eg 20 (edit: no, more than that - 50?). ICBW about this - just trying to make sense of an observation!

The LOOP packet is not something I understand well, but this is a regular in my MXdiags

OK, thanks. I didn't think to look in the DIAGS. But leaving the LOOP2 stuff to one side, that looks like it's requesting 50 LOOPs at a time.

What's slightly curious is doing this every (I think) 63 seconds or so - that looks to be asking for roughly twice as many LOOPs as are actually available in that time (Davis suggest that a new LOOP is available every 2 seconds, but no more often than that). Not that it matters I guess - it obviously works.

Anyway, thanks. That explains what I was seeing.

It requests 50, but every minute it sends other commands that terminate the loop processing, then requests another 50 etc. I guess Steve requested 50 so it would never run out ;)
