Maybe a bit off Topic. I have been using Tophat for a few years now. I started running it on a Nook Simple Touch. I loved the black and white sunlight readable display, but after a couple years the Nook seem to be getting slow. So I tried a Nexus 7. I liked the color display (hint turning the Terrain display off helps a lot) but it is not near as sunlight readable as the Nook was, but was good enough 95% of the time or better. Only when the sun was behind me would I occasionally get a glare on it that made it unreadable until I turned or shaded it with something. After a year or two I upgraded to a Nexus 2 - 2013 which had a slightly better display and was faster.

The other thing I really like about the Nexus is it is a totally self contained unit, It has it's own GPS so you can literally just carry it to the airplane and go fly. I had K6 Bluetooth adapter attached to my FLarm so with a bit of configuration it was receiving Flarm Data as well. I do sometimes connect external power to it, but the Nexus usually will last a 5 hour flight just fine.

Last year I put a S80 in my glider and added the Bluetooth module, It works pretty well but the bluetooth module is not quite as robust as the K6 module. The S80 bluetooths occasionally(almost Rarely) requirs a restart of the tablet or S80 to get it to link up, but once linked I never have any trouble during the flight.

A couple weeks ago flying the Region 8 contest about 9am I discovered my Nexus 7 touch screen had died, it would not respond to any touch commands. at 10:30 after the pilots meeting I went to the local Walmart and purchased a Samsung Tab 7 8gb for under $90. (they only had a display model available, normally $120). By the 1pm launch I had updated the software on the Tablet, installed Tophat, the Waypoint, airspace, and terrain files and had configured it to communicate with my S80 and had a working flight computer for the day. In summery I went from no flight computer other than the (S80 that I use for a backup) to my normal working flight computer in under about 2 hours and under a $100 investment. Try that when your dedicated flight computer dies, it may cost you more than that in just shipping and won't be a same day fix.

I am actually very pleased with the Samsung, The display is as good or even slightly better than the Nexus and it is faster. I wish it had a bit more memory than 8GB but does have a place for a MicroSD card if I need more space. I ran it with power connected, so not sure how the battery life is with it standalone, but It seems like it would be as good as the Nexus.

I think Tophat works very well, I only wish it did a bit better job a providing tactical Flarm traffic information. I don't use it for traffic avoidance but it would be nice if it kept track of Flarm traffic a bit better. Something like LK8000 or some other displays (Avionic) that show where traffic was or might be even though the signal is gone. With the right display it could even show Statistical climb information about the other gliders thermal and even mark a likely location to intercept the same thermal even after other glider has left the thermal. That way I don't have to be looking at the display as much or take near as long to trying and calculate information that computers are very good at doing.

To the original question, with nothing other than the minimum required changes Tophat, on the Nexus and Samsung, automatically switches between Thermalling and Cruise mode with and retains the zoom level for each screen, usually zoomed in for thermalling and zoomed out for cruise for me. I have never had issues with this no not sure why others seem to be having issues.

I recently bought a Galaxy Tab 7 tablet and tried Bluetooth connection with the k6bt2 but was not able to connect.
I contacted the k6 folks and I was advised that the k6bt2 is needing "profile SPP" which my Tab does not support and it will not work. So... what am I missing here? Wrong Tab??
