Hi there, we are doing assessment surveys requiring a large number of media files (photographs) to be collected in each submission.
We already request enumerators to set camera settings as low as possible, and are aware of the 5MB limit per attachment/photograph. Currently there are up to 15 photos per submission however ideally (in order to suit the ideal data structure/logic) there would be more photos (up to ~80) per submission. This would allow us to capture all buildings within a complex in the same survey form, rather than requiring our enumerators to re-enter common data for each building).
However, we are finding that even with Head Office internet (let alone with the slow internet in the field) the KoboCollect uploads are often unsuccessful even with the current number of photos. We are regularly getting “Write error. IO Error during system call. Broken pipe.” and other errors when trying to upload data from the tablets. Each individual media item was around 1.5MB so well under the 5MB max.
I have since been told that perhaps the 5MB media file size limit applies to each submission rather than to each file
Can someone please advise what the Maxima are of the KoboCollect tool connecting to the Kobo Toolbox site when uploading submissions involving media files?
I realise we can manually upload if necessary, but that requires technical capability that some of our enumerators don’t yet have - so ideally we’d design the survey so it fits within any technical constraints in order to allow auto-upload.
