At the Toronto competition, we suffered communication problems throughout. The robot would lose connectivity anywhere from 1-4 times a match, with a duration of about 10-20s each time.
Using the Cortex 2.0 (NC 1), and programming in RobotC, we tried a few possible solutions unsuccessfully:
- Using 9V Backup Battery - wasn’t used for much of the competition, but adding it didn’t seem to resolve any issues.
- 5ms wait in main loop - reccomended to us by a team who had been having similar difficulties, but didn’t solve our specific problem.
The loss of connection doesn’t seem to be related to power draw, and my only thoughts at this point are that we’ve heard of bugs in the NC1 version of the controller.
Thank you for your consideration.
