Our rbr (not rbr 2) performed very weirdly. Almost every time we powered it up, it would disconnect after a random time period (~several hundred seconds). This would also happen when the robot was kept disabled. We already switched roborios and flashed the image and firmware of these rbrs, but those didn’t work. When it was disconnected, the COMM led on the rbr kept green, even when we later unplugged the ethernet and USB cables. The only solution we had so far was to reboot it physically. It seemed like the rbrs were stuck in some mysterious state. Btw, the ds could connect to the radio in this state, but just not the rbr. It didn’t happen in the past seasons.
Since we changed rbrs, we thought this might be a program issue (from the codes). However, there were no crash information. We suspected that this might be due to full memory on the rbr, but we couldn’t confirm because sometimes it just disconnected when the last log in DS said that there’re ~50MB of memory left. Are there any suggestions? including ways to confirm the memory usage? Thank you so much!
