Before, I had only seen it on our comepetition robot while connected to the FMS, and I thought it was related to the clock issue mentioned earlier, but yesterday it happened twice on the practice bot, which has a diffferent roborio and NavX board. I would say it happens about 1 in every 10-12 robot starts.

I haven't tried I2C or UART, but we may switch protocols for Lone Star and see what happens.
In the case where the 'Data Valid" output is false, do you know if the "Opened" indicator is also false?
