Were you able to test this tablet out with an USB to Ethernet connector? If so, did it work well?

My plan for getting the data off the tablet was to use adb network forwarding to allow the tablet to connect to a web server running on a host computer (all the tablets would be connect to this computer in the stands).

I like your idea of using ethernet since it removes a lot of the complexity with spawning adb instances automatically for each tablet. I ordered one of these adapters that I'm going to try with a USB OTG cable. I'll let you know how it works when I get it.

I'm not sure if this has the functionality you need but in terms of price I don't really think it can be beat.

I have one right now and I like it. It has some trouble with Wifi, but if you are using ethernet it should probably be fine.

Be careful relying upon WiFi; this has generally been prohibited at competition in the past, and is likely to continue to be prohibited.

We use bluetooth to transfer data between tablets. Works very well.

Don't end up with a junky Android tablet that will be unbearably slow and see limited manufacturer support and updates.

This Asus model is essentially a re-launch of the Nexus 7 from 2012, and it's gotten good reviews from AnandTech and others.

You could also look for refurbished or open box Nexus 7's (2012 edition), they should hit that price point or lower.

Someone told me recently you can get one through Walmart for $69 using the internet shopping and have it shipped to a store.

Not the Nexus 7 (http://www.walmart.com/ip/Nextbook-7...vices/22127002)

Perhaps it was me?
Walmart: XELIO 7" Tablet With 4GB Memory, currently $44
I bought this, installed Google Play (get com.android.vending-4.1.6.apk).
Works fine. The screen resolution is not great, but great deal for $44.
No Work: Vibrate, compass
Works: GPS, WiFi, Accelerometer, everything else...

How does it feel quality-wise?

It's not iPhone quality. But it is better than $44 quality.
The biggest complaint is the screen and that the touch-pad registration is slightly off. You need to touch a bit higher than you expect. I guess I got used to that. Battery life seems OK. I can download files to it via USB, though I can't use it for Android development (driver issue.)

Walmart has smaller Android devices for $35. I'll evaluate one shortly. We are considering buying a bunch of them for a judge & RI app. Pls check it out at

I'm not sure where you're getting this from. Can you cite the rule?

I know they prohibit bluetooth on the robots and operator console, but in the arena I believe they only prohibit wifi networks.

False. All past rules have specified wireless devices following the 802.11 standard to be disallowed, but Bluetooth and zigbee follow the 802.15 specification.

OP: For ideas for implementing your scouting system, you might want to checkout the post and whitepaper Team 1678 has on this thread:

We used 8 Trio Stealth Pro 7' tablets for our system and they worked kind-of ok. They functioned mostly as we expected, but you get what you pay for with Android tablets under $100. They did not support Bluetooth, which was a disappointment, but they DID support USB ethernet, which we used at the Sacramento regional. I would not recommend using USB ethernet though: it seemed somewhat unreliable and a real mess with cords. At this point in time, I would recommend increasing budget a bit to $150 per tablet, and purchasing ASUS MeMOPad HD 7s
They are pretty much just marked down previous-gen Nexus 7s, and from what I can tell the gain in quality from cheap less than $100 to $150 makes a world of difference.

At least that was my / our teams experience, maybe it will be different for you.

Good luck!
