So many great ideas coming from everyone! It has been really cool to see the collaborative spirit here, in #internships and on the Collect repository.
Absolutely. I know @dexter21 has also been exploring along those lines. I believe it should also be possible to initiate wifi direct pairing with a QR code if that provides benefits.
There is some interest in adding support for SMS submissions which you can read about at Send submissions via SMS. For this particular project, the goal is to use a free transport layer that works well in close proximity. SMS can be very expensive in some locales and it can be unreliable.
The UI looks really nice! For the summer project the recommendation is to enable the functionality in a companion app to reduce needed changes to Collect and so that users who don't need the functionality won't be overwhelmed with a new feature. But this shows a nice path to integrating it.
