High-res data saving fail

For reasons that are unclear, saving high-res data on my Go is not possible when data is collected in roll mode. Hardware version 4.0, firmware 591, software 3.2.2 build 28558. Behaviour shown in this video. Other files save fine, just the high-res fails.

I’ve tried the obvious power cycle and software reboot.

Hi BenB,

Thank you for sharing your problem.
Unfortunately, we do not support saving high-res data in roll mode at the moment. You can save either high-res data in normal time span, or as a trace in roll mode. We are aware of this logging problem and hope to fix it soon.
