I have a Pi3 installed and it collects data great. when I go offline camping I was thinking that it would store this in a DB to upload then the internet returned but it does not. am I missing something? should this work? is there any way to get it to work? can I l log to a file and upload?
I also expected this to work but it doesn't. I think on the Cerbo(?) you need to insert a MicroSD card for the data to be stored on. As my Pi has plenty of storage, I suspect all that's really required is a mod to either link the file system directly, or create a data store partition (to emulate the separate card) and get that mounted appropriately. Perhaps when I'm less busy I'll have a play, and if I get it working I'll submit a PR.
I think logging to file and manually uploading is supported in some situations. However I've not seen and VRM GUI that suggests how to do this. I think it may be in the Cerbo manual though.
We experience the same issue with logging devices that we have built using Raspberry Pi's. We have expanded to ensure that all available SD card space can be used by Venus OS but for some reason on Pi, it does not replay logs when it comes back online.
Did you get anywhere with this @AlexHeylin ?
I'm digging into this more over here:

@benc_ipind sort of - I tried to reproduce it recently (after a few updates to Venus) and it seems to work now but I need to be patient. It might take 15-30 mins after the Wi-Fi / Internet connection comes back online. I've had my Internet drop out for a few days a few times in the last couple of months, and as long as I don't reboot the Pi it seems to eventually pick up and send the data out. Streaming the data out can take 30-120 minutes depending how long it's been offline. I think previously it wasn't reconnecting to the Wi-Fi / didn't realise the Internet connection was available again.
32GB is about as small a card as you can reliably get these days, so you end up with 20GB of 'wasted' space.
