Re: [Announce] modRana: a flexible GPS navigation system
 

I already had 0.26-2 when I wrote that, it says unknown version.

There is no version.txt in /opt/modrana/

Re: [Announce] modRana: a flexible GPS navigation system
 

Just a heads-up to people: since I made my turn-announcement changes, I've noticed that I don't get proper (for some definition of "proper" :-D) announcements when turns come in quick succession. (It happens that the last three turns to my house are under 100m apart, so I get a lot of chances to test it.)

I'll look at the code when I get a chance and see if I figure out why I broke it or how to improve it. Meanwhile, if your map shows a bunch of turns close together, be alert!

Re: [Announce] modRana: a flexible GPS navigation system
 

Some tile providers don't like batch downloading and return an error pages in place of a tile - which results in this kind of errors you are getting.

I think I remember somebody reporting some other DBUS related errors though I don't remember how or if it was solved in the end...

Some more things to try:

• just running modrana without the sudo gainroot and posting the result (but it works in my case even as root)
• reinstalling
  
  Code:

  ---

  sudo gainroot
apt-get update
apt-get remove modrana
apt-get install modrana

  ---

• checking if python-dbus is installed (it is listed as a dependency so it should be...)
  
  Code:

  ---

  sudo gainroot
apt-get update
apt-get install python-dbus

  ---

• rebooting and then running modRana (I have seen some mentions of DBUS related out of memory errors like this one in Google search results...)
• upgrading to 0.26-3 - no idea how it might fix your issue, but why not :)

I have released V0.26-3 that has the version file and is also build in a more "standard" way.

Well, thats weird - i have checked the repost and libmagic1 is normally available from repos and on device installable.
You can try to run this in the terminal to manually update your repository listing, install libmagic and then modrana:
Note that when modRana gets a new voice message while there is already one playing, the new one is skipped.
IMHO your patch only increases the distance - so maybe it just increases the distance for short segments to be larger than their length, so that their announcement is triggered at once when switching to the segment and then being skipped because the last announcement is still playing ?

Thanks a lot in advance ! :)

I have done some road testing the new code:

• the new code works good :) (aside from the above mentioned short segment issue)
• some long on-highway segments have announcements too far ahead
  This is caused by Google setting the default turn distance too high (I have seen 2,5+ km, which is IMO too much even on a highway).
  In extreme cases the announcement might be even skipped due to overlapping with the last one.
• generally when on highway (long segments + high speed), more announcements at a varied distance would definitely be handy
• I have hacked in some rounding to the voice output (325 meters -> 320 meters) which made it definitely quicker to "get to the point"
  Some more advanced rounding might make it even quicker (300..330 = 300, 333..367 = 350, 351..400 = 400, etc.).

Re: [Announce] modRana: a flexible GPS navigation system
 

Yes, all my patch does is to increase the distance, so I bet that's exactly the problem. The fix would be something like "if an announcement is playing and we're still ahead of the waypoint, reduce the distance so we can try again in a little while."

In my area, Google sometimes does the opposite. My favorite is that the waypoint for "take the exit" from a high-speed road is sometimes at the END of the exit so that if the ramp is a long one, you have to be on the exit before you get the announcement.

I agree with the "more announcements" thing. When we moved to New Zealand we rented a car with a GPS, and it would often announce the next turn many km ahead and then give a sort of count down. It was very helpful.

The rounding is a really good idea; "In 321 meters" is kind of silly when you're traveling at 20+ meters per second. The trick will be to make it sensible at different speeds, short distances, and in both metric and U.S. units. I tried to fiddle with some advanced rounding code in this post and quickly discovered that it's a bit trickier than what I want to do before breakfast! :-(

Re: [Announce] modRana: a flexible GPS navigation system
 

Reinstalling didn't fix it. Python-dbus was already installed/latest version.

Tried again in CLI mode with latest version, this time without typing sudo gainroot. Seems to be complaining about a mod_location module.
Any help?

Re: [Announce] modRana: a flexible GPS navigation system
 

The problem is that the "simplejson" package is missing. On my N900 it lives in /usr/lib/python2.5/site-packages/simplejson. Fine, I think, so he just needs to install it. But here's what I get when I try to figure out the package name:

scroll:~# apt-get install simplejson
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package simplejson is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package simplejson has no installation candidate

A bit of Googling reveals that it's actually named python-simplejson. I suspect the problem might be a wrong dependency in Modrana? Anyway, you should be able to solve it by doing (as root):

apt-get install python-simplejson

Good luck!

Re: [Announce] modRana: a flexible GPS navigation system
 

hello, I didn't read whole 740 post so, sorry if it is being asked twice,

How can I download tiles to my pc? I should find a way to do that because I chose around here, 80 km, +8 down, +5 up (or sth like that), modrana says ~355000 tiles to be downloaded. I left my N900 to download them last night, at the morning I saw it downloaded 30k of them, AND was downloading too slow if I compare to beginning. So, I need to download them to my pc then should move them to n900. Tiles are in /home/user/MyDocs/.maps/OpenStreetMap I , I guess ?

Re: [Announce] modRana: a flexible GPS navigation system
 

That fixed it - many thanks

Re: [Announce] modRana: a flexible GPS navigation system
 

Thanks for the info ! :) Looks like the new GPSD support module, which depends on json, was imported even when not needed (as modRana uses liblocation in its place on Maemo).
I have added python-json as a dependency and a pure-python version as a backup (well, it was actually already there for the googlemaps module, but I made it accessible for all modules).
All this should be in the in V0.26-4 that was released a few hours ago.

@on PC tile download
Check out this post and maybe posts around it. :)
I think there really needs to be a wiki page about this. :D

Re: [Announce] modRana: a flexible GPS navigation system
 

interested on this one. also any chance for a simple converter to convert it to sqlite format? for less space.
