The "progress bar" is a rough indication of the signal strength that you currently have. A full bar means you have plenty of signal. A half-bar means you may or may not have enough signal to acquire a fix (depending on your receiver). If it doesn't make it past the "Establishing GPS fix" progress bar, though, then your receiver is not indicating to Maemo Mapper that it has a valid fix. It may still provide lat/lon information (and Maemo Mapper will still use it), but it in that case it may be wildly off (so most receivers don't even bother guessing).

If you can never get a fix regardless of where you go, I would return the receiver and look for one with better sensitivity.

ReinhardE is right - when in doubt, enter the address(es) in http://maps.google.com/ and it should tell you what (if anything) is wrong with the address.

Very nice!! Great work, glad to see more progress on MM.

just took a 700+ mile round trip and MM worked quite well. biggest issue (and one that annoyed the wife to no end as she had to "fix" it) was that it kept loosing the GPS and only rebootong the n770 would bring it back. I do have "user ALL = NOPASSWD: /usr/sbin/hciconfig hci0 reset" in place and running the command in an xterm does not produce an error. in MM when the gps connection is lost and reconnected I get a very generic "error while scanning" message. the GPS seems to work fine otherwise and the time it takes to error seems completely random. first time was after 6 hours of driving, and then it was very frequent (10-20 minutes) until I unpluged power from the GPS and ran it on battery, then it was only every 3-6 hours. it seemed most likely to fail right before a complicated interchange . maybe the hci reset isn't enought? could the bluetooth drivers be unloaded and loaded again? and any idea on how to prevent it from needing reset in the first place?

also, trying to "download along route" at zoom level 3 and lower for 700 miles seems to overwhelm it even with swap enabled. ended up just zooming in on the towns I wanted and downloading those manualy for the lower zoom levels.

my only other gripe is that google driving directions are on crack. it would occationaly tell me to go off onto a secondary road when the highway simply S-curved a bit. due to this, the turn-by-turn pop-outs wold not appear without manual intervention. anyone know of a way to export Streets-n-Trips directions, or a GPX compatable service that works as well?

overall, quite the lifesaver! kept me from being completely lost when i decided to avoid the i-80 construction in south Chicago on the way back and jaunt across rural IL and IN from i-65 to i-57 via secondary roads (wife hates it when I do this too)

I did the same on a long trip recently! I've since learned from a post on here that switching to offline mode and back also fixes things and is a little easier.. possible without wifely help, even

It happens often enough to me that a button on the screen, or a key combination to initiate the reset would be useful.

ah, I guess going offline could unload the bt driver

Good idea. Here you are: http://eko.one.pl/index.php?page=Nok...g%20BT%20radio. ESC button now is "BT radio reset" button, of course you still need add line to your /etc/sudoers. Code taken from previous version of maemo-mapper. Please, test it.

I had the same issue and also did the 'sudoers' trick but didn't work for me.

After my vacation with the Nokia MeamoMapper System I tried the '/dev/rfcomm' trick and this works perfectly; no loss of BlueTooth GPS connection at all.

I modified my Nokia so it will automaticly connect to the GPS unit when I startup Meamo-mapper. Modify the /etc/bluetooth/rfcomm.conf file. (first gain root access to do this)
Replace the sample values with your own values (MAC address) and set BIND to yes. Then the connection will be established at each reboot.

Now even when I switch off the GPS or get away from my Nokia with it it reconnects immediately when switched on or get nearby again.

Question: Is it so that the BlueTooth hardware is now always active (and searching) and is draining the battery more if I don't use Maemo-mapper?

I'd think it would, though you could switch to offline mode and then it wouldn't (btw, where is this offline option? I odn't think it's just unchecking "enable gps" because that did not "fix" it)

It's in the menu when you press the on/off button once.
