I am very glad to announce that after many nights of debugging I could finally fix the nasty switch off/on issue! The issue caused loggers to crash during switch off in random cases. They couldn’t be switched on until batteries had been removed. I know that some pilots experienced stressful situations if the issue occurred.

I just published the new firmware release 1.2.178 which contains the fix and also a few cosmetic improvements.
I would like to thank the guys from Flytec for their support in resolving the issue.
