The solution that finally worked for us was cycling the power on the access point as we entered the field.
Has anyone had any experience using a shielded Ethernet cable? Was reading a bit about it here: http://www.l-com.com/content/FAQ.aspx?Type=FAQ&ID=4803 |
At the Central Valley Regional we had connection issues in all the matches except two. After changing all the electrical components and then some on the 9th match we started working but not at first. When our robot was brought onto the field the same connection issues were apparent (no connection dropped packets) Two FTA's went on the field and after they came off we were connected. After the match I asked the FTA what he had done and he said they connected the driver station to the robot when they saw no connectivity and it connected ok through a cable. But when he disconnected the Driver Station the radio would not connect to the field so he powered off the robot to reboot the robot. When it came back up we have connectivity for the entire match. Next match we make sure we do not connect the robot to our driver station by cable or if we do we power the robot off then on and so on our last match we ran again not perfect because of the code we had running but we ran the whole match with few lost packets. My guess is we were actually cycling power to the bridge as we entered the field as you stated above.
