Re: Communication Issues?

At the BAE regional, we were very lucky to be contacted by the FTA after a few practice matches on Thursday because they had noted that our packet latency was very high... on the order of 10x the rest of the robots on the field. We turned off a few items on our dashboard (although there weren't a huge amount on there to begin with) but were asked to come to the field during the link testing after all practice matches were completed. (The link test is for teams which have not made it to any practice matches to verify that they can connect to FMS successfully before the qualification rounds begin). During that testing time it was determined that the initial problem with our communications was in fact a bad D-Link. When it was replaced by one from spare parts, we were good to go.

However, the FTAs continued to monitor our comms through our beginning matches on Friday... and at one point sent over a volunteer to tell us that we might be experiencing some additional communications issues and we should verify that our camera frame rate was no more than 15 fps. When we checked this we noticed that we had never touched that parameter, we had only configured the resolution to be smaller. Upon turning down the frame rate we ceased to have any comm issues observed by us or the FTAs.
