Hi, first of all congratulations to the development team, you've done a tremendous job!
I was wondering whether it would be possible for the devices to record on alternate days (or once every given number of days).
Is there any perspective for such feature to be included in the firmware? If not, would it be possible to customise the C code to do so?
Right now the firmware does not support this functionality, however I believe it would be relatively simple to customise the C code to do it. The code already keeps track of the current day, so it would be a case of using that to decided whether or not to record.
