I get one or two file system mount related failure messages on boot as well but it seems to work fine.

Testing thismorning and I forced PilotAwareAndroid to stop after all detected and location found. I wasn't moving when I did that but Skydeamon continued quite hapily.  I could see ADS-B traffic moving my no warning that I'd lost my GPS.  Thats a bit of a concern.

I noticed this too - I put it down to SkyDemon using the tablet GPS directly for its location info and PilotAware (ADS-B side) for traffic, but the ARF interface on the PilotAware would no longer be getting position information to transmit on the ARF radio side of things. Is that right ? I can't test the ARF side yet.

I'd vote for max range in hardware and declutter in software if necessary

Slightly more complicated I'm afraid 
In a random access system, its important not to swamp the available bandwidth,
Otherwise transmit packets can overlap thus corrupting the data.
So its a careful trade off between

Transmit power
Transmit datarate
Repeat period (+backoff times)
Packet length

A lot of thought has gone into optimising these parameters, and there is likely to still be some tuning of power and datarate, thankfully these are all controlled by software not hardware

Thx

Ah I was thinking "declutter" was meaning just controlling the amount of things displayed onscreen.
Interesting - what bandwidth does the interface have ?

Yes I followed your lead and used the SOP - see Model B thread for pics / diagram

Is the support for the GPS in the current release? or is there a Beta with it in?
I hope to have my GPS end of this week

I could get a beta uploaded for you to try
Let me know if you want to give that a go.

I'm happy to buy in a GPS and trial the beta - I'd prefer a GPS that is both GPS and GLONASS though if possible - hence my interest in this one: http://www.ebay.co.uk/itm/281788291544

Can you confirm if this is likely to work or will require additional coding? Assume it is presented as a USB serial interface?

How old is the Galaxy tab mini and which version of Android are you running.  Check Settings > About Device > Android version.  Some of the code required slightly more up to  API features so older versions of Android might not work.

For info my old Asus Memopad is running 4.2.2 and is OK

I am stuck on an older version of SkyDemon though: 3.3.2.20289

Try this Chris:

- ensure your device will only connect to the PilotAware wifi

- get everything up and running

- pull the plug on the Pi

- plug in Pi

- Go Flying again in SkyDemon

For me I need to close and reopen PilotAwareAndroid before it will work again

Works basically well on my Asus Nexus style Android tablet as well as on the iPhone. Thanks guys.

Chris - sometimes Skydemon seems to get stuck "Searching For GPS" and closing and re-running the PilotAware app on the Android tablet seems to fix it. Perhaps there are some combinations of order of startup or parts coming and going that aren't quite covered. Not sure I can accurately reproduce yet - will try and get a clear reproducer and report back.

4) Plug the ARF antenna in, drill the 6mm hole in the case and fit the antenna in it, then plug in the SOP board and fit the case top ...

3) So here's the ARF when the soldering is done. I stuck it to the SOP with some double sided sticky pads.

Here's the wiring diagram for the SOP to the ARF board. Just 4 wires.
