Weeeeellllllllllll, I'm going to give RT a go. GPSRL I agree can be flaky and I put up with it though I have had much better luck with an HC-05 B/T module with my
Nexus 7's. GPSRL seems to be working better for me. I went ahead with Rocket Track to try and see if it caches tiles but it appears it doesn't so it needs a live link.
I got a FreedomPop sim in my N7 2013 LTE with about 5.5Gigs of rollover I certainly could tap. Yeah I know all the BS quirks with FP and it's o,k. with me.
Thanks for pointing out Rocket Track again as I wrote it off in the past. I didn't have a device with a phone sim in it at the time. I did do a successful recovery with GPSRL without maps and had to triapse through a field of obstacles to make the two icons "come together". I swore never again after that when I realized I could have driven onroad, taken a short walk and picked the rocket up. This was before GPSRL could cache maps and I was
stuck with a Nexus 7 2013 Wifi only, the "Flo" version.
I like to have "backup" in several forms so RT is going on my devices now. If GPSRL gets flaky, (though it hasn't for me in a long while) I can fire up Rocket Track as I now have sims in a couple of tablets.
Many times when I've tested out GPSRL I've used a receiver with the BT module epoxied on the outside:
After it's paired to an Android device, the LED stops flashing for a moment and then starts flashing again. I fire up GPS Rocket Locator and
point it to the NMEA receiver and when it connects, the LED goes solid. Sometimes the "connecting" part takes time but
if there is a good satellite lock on both ends GPS Rocket Locator fires up quickly. Then again, Murphy can sometimes set in and I haven't
had that happen during a launch but I have experienced it with testing at home. Rocket Track for me is a good backup and for some might
be a primary app as long as they have internet access at their site. If they don't, it won't paint maps. Kurt
