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?
What really happens is that, whenever an application opens the /dev/rfcomm device for reading (or writing, I imagine), the bluetooth driver only then looks for and connect to the device. If the device is not present, I think it returns EOF or a failure condition or something. When the application closes the "file", the connection is dropped.
So, it won't drain your battery unless you leave Maemo Mapper on (without the cover on the display).
Using rfcomm this way may, in fact, be the (unfortunately) ideal solution to the dropout situation, until Nokia (or whoever) fixes the bug that causes the dropouts.
GPSD may also be a potential solution, since I think it uses rfcomm.

Then just remove the number after mt and replace the x, y and zoom values with %d to get:
http://mt.google.com/mt?n=404&v=w2.17&x=%d&y=%d&zoom=%d
looks like the one in the earlier post had an extra % in there

Hi,
my next patch: GPS Info, display some textual GPS information (lat/lon, speed, satellites info, gps time (with local time zone). Details: http://eko.one.pl/index.php?page=No... 20maemo-mapper. See screenshot.

Well you had me in a bind for a while there, but now all is well again :-)
The old URL indeed doesn't work anymore, but this new one doesn't either, at least not here over Europe... and I was going to try out maemo mapper on the holiday trip on thursday... Oh, well.
