After that match I switched out our radio (all of our radios were reprogrammed for CMP) and went to match #2. We connect for approximately ten second and then it dropped. The FTA said "I have no confidence in your radio" and we were bypassed again. I then received very generous help from some FTAs and control experts (in another thread I explain their extreme kindness) who ended up downgrading my radio firmware version from 1.4 to 1.2 and then we decided to disconnect our two radios. By the odd event of a balsa wood airplane coming on field we were able to replay match #1, but this time with our dual camera system disconnected entirely. From then on I never had issues connecting to the field and never replugged in either camera. The FTAs mentioned that dual camera had caused problems for other teams.

I dont know if the dual camera issue was the problem for anyone else. All i know is, my controls freshmen have a sworn vengeance against camera now..
We had a similar issue at Davis in which our comms were dropping after a few seconds into the match. It turned out that absolutely nothing was wrong with our radio -- the resolution of our camera feed, when using dual cameras, was simply too high, causing the memory on either the cRIO or driver station computer (I'll get back to you on which one) to overload, which resulted in packet loss and a lost connection.
