Live Scouting Data Transfer

[peterl]

This year is our teams 2nd year doing match scouting using android tablets. We have been using PDF Forms for every match, and later in the day collecting the tablets, and copying the data using a pc. This year, the drive team has asked that we give them "live" data. I am still looking for clarification as to what they mean as live, but for the time being, lets say every few matchs. I was thinking using a USB hub and having all the tablets connected and I did a trial of that last year, but I ran into the issues of cable lengths and people unplugging them (accidently), or not having enough power for the hub.I am curious about using Bluetooth, but am unsure about the ease of transfer, being that I would be doing this to 6 tablets in a short period of time. Any thoughts or ideas as to how I could manage this. We really don't want to rely on a app developed by another team because we want to be able to edit the form before the next competition to collect different data etc. and we currently don't have enough manpower to develop an app.

TL;DR: I want to collect PDF files from android tablets during a competition, to a pc, with out disturbing the scouts. How can I do this? Or is there a better way to do this?
