00:34 <****> spam on the mailing list !
01:00 <****> hi
01:21 <****> I have gps working but no matter what I do I cannot get a fix (A3). With a bluetooth gps beside my moko I can get a fix every time.
01:22 <****> Debugging suggestions?
01:22 <****> Are you outdoors?
01:23 <****> put it outdoors for 5 min, where it hasa a good view of the sky
01:27 <****> i cant get a fix on the neo no matter what I do. my n810 works great
01:28 <****> ljp: tried outdoors?
01:28 <****> yes
01:28 <****> :/
01:28 <****> n810 works like a charm
01:29 <****> Is yours a production (paid) unit?
01:29 <****> I have aa IOGear gps and I can just put it by the window. It locks without any problems
01:29 <****> neo? yes
01:29 <****> i have even tried an external antennae
01:29 <****> jeremym: some GPSs are rather better at locking than the neo in weak signal conditions.
01:30 <****> external antennae? Can msg me a link.
01:30 <****> I was thinking I may need one.
01:30 <****> not sure where we got it. i just know one showed up on my desk :)
01:31 <****> What kind of connector do I need.
01:31 <****> ljp: I'd suggest poking one of the devs.
01:31 <****> Also - take it apart, and check that the grey antenna wire is not pinched
01:31 <****> someone said to take it apart and check the leads
01:31 <****> possibly me.
01:31 <****> I have maemo-mapper hacked enough to come up. Though I can't get a location lock. Now that bluetooth is working on my neo I can continue developement.
01:32 <****> :/
02:21 <****> what kind of connector is the external antenna?
02:21 <****> for the gps that is.
02:21 <****> the one on the side
02:21 <****> dunno the name
02:22 <****> I would like to buy an external antenna but need to know the name.
02:22 <****> Is there a way to make the GPS run at higher power?
02:25 <****> no, there isn't.
02:25 <****> gps is passive.
02:26 <****> yes there is. An antenna with gain.
02:26 <****> Determining where to point it is interesting of course :)
02:26 <****> however.
02:26 <****> Active antennas are widely available.
02:26 <****> The problem is that you have no real reason to suppose that it'll help.
02:26 <****> well, a antenna doesn't make the gps run at higher power :)
02:27 <****> Diddn't help ljp for example.
02:27 <****> but you're right of course
02:27 <****> but I've never seen an active antenna
02:28 <****> they are common
02:28 <****> if I knew the connector type for this thing, or are they standard.
02:28 <****> ?
02:28 <****> so it's an antenna plus amplifier, SpeedEvil?
02:28 <****> thomasg: basically.
02:29 <****> jeremym: the neo uses a standard-connector
02:29 <****> http://cgi.ebay.co.uk/GPS-Active-Antenna-for-Mio-168-268-269-C510-C710_W0QQitemZ150196580507QQihZ005QQcategoryZ139836QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
02:29 <****> first of a few dozen hits
02:29 <****> jeremym: it's called MMCX
02:29 <****> I was looking at these: http://www.wi-sys.com/products/antennas/gps_antenna.php
02:29 <****> SpeedEvil: so where's the active part of this antenna?
02:30 <****> I don't see a powerconnector, only the mmcx-connector
02:30 <****> or do they call antennas with a gain "active"?
02:30 <****> there is a bias voltage applied to the connectors.
02:30 <****>
02:30 <****> there is a bias voltage applied to the connector.
02:30 <****> and it powers the amp
02:31 <****> ok. the neo supports this bias?
02:31 <****> I don't know if the neo needs software to enable the external antenna. roh?
02:33 <****> no, that's not what I meant. the bias-t normally works with a defined DC voltage which must be available on the mmcx-connector - I do not really know how this works for gps-devices, is this standard?
02:33 <****> I think there is a sort-of-standard at 3-5V
02:33 <****> I haven't really looked into it.
02:34 <****> as the gps is only a reciever and works passive I assumed that there wasn't any active power for antenna connectors, but I might be wrong.
02:36 <****> I tossed my neo out on the street in the hope that it the GPS will lock and that it wont rain or snow ;-)
02:38 <****> SpeedEvil: ok, I found a description for an active antenna which includes a 3.3V DC powered amplifier that is powered over the mmcx-port.
02:39 <****> every day new things to learn :)
03:41 <****> is there a known way to revive a "locked" neo w/o disconnecting the battery?
03:42 <****> locked?
03:42 <****> the powermanagement-feature
03:43 <****> doesn't the power button work?
03:43 <****> not for me, no
03:43 <****> if you hold it for 8 seconds?
03:44 <****> ..6..7..8... no :)
03:45 <****> it answers icmp ping but I cannot connect over ssh
03:47 <****> thomasg, i have to take out the battery
03:48 <****> daMaestro: same for me, hoped there would be another way
03:48 <****> thomasg, let me know if so
03:48 <****> I will
03:48 <****> i just stopped using lock because i figured it was just a software bug
03:49 <****> ya, but I wanted to try it again after some weeks and some updates. still doesn't work :)
05:29 <****> anyone got a picture of GTA02 ?
05:32 <****> afaik, it looks like GTA01
05:41 <****> Hi all
05:41 <****> when i run make setup of the mokomake file, i am the following line
05:42 <****> Fetching external item into 'openmoko/tags/repository-before-first-cleanup-2007-12-12/src/target/OM-2007.2/applications/openmoko-today2/libkoto'
05:42 <****> after that there is no network or disk activity
05:42 <****> what could be the reason ?
05:45 <****> Hello Everybody
05:45 <****> Is there an alternative svn mirror?
05:47 <****> can any one reply for my question ?
05:48 <****> Hi sreekanth what is your question ?
05:50 <****> Atul_: sreekanth's problem is, he is not able to checkout openmoko svn tree completely when he followed http://wiki.openmoko.org/wiki/Building_OpenMoko_from_scratch
05:51 <****> Atul_: Both me and sreekanth are try to setup a development environment,
05:52 <****> raddy what you people are trying for
05:52 <****> means you want to setup an moko environment
05:53 <****> raddy, why you try for 2007.1 build try for 2007.2 build it is most recent and stable
