Topic: BUGmodules / BugLocate / GPS : moving is bad.

Thanks for explanation. I never had problems to get a fix. Sometimes, but peharps it will not happend again with the update, led blinks green but datas continue to be sent as if it were not. In these case, restart concierge resolve the issue. Hope this will help others.

I do not know why one of my sentence is strikethrough, considere it as not strikethrough.

“could you explain me with first age words what did you mean with “time-to-first-lock” ?”

Hi again Edrae,

It is the duration of time it takes for the GPS receiver to get a postion from Satellites.

Thank you for taking the time to post here. This will be useful to other users. We are a small company and we need to work on communicating these changes better.

Topic: BUGmodules / BugLocate / GPS : moving is bad.

Hi Brian,

I saw something about this update but because I’m resistant to configuration stuff, I didn’t go ahead. I also didn’t think that driver update could fix my problems, I believed it was the api that goes wrong. I thanks you and JConnolly to bring me commands to enter words by words.

So, I didn’t have the time to make a full test but for now, improvement is great. This is what I did and the results :

Get a fix from my window and make a circle in my narrow garden => position is not fully correct and precise under the 3m but put some zigzag in about 30m (my garden is about 5 by 10 m, all of this with a realy big “about”). So it is better without being perfect.

Then, I go to my car, made a trip around a block and go back to my starting place => just excellent results !!! The position is almost perfect, When in my car, I can say it is was I’m waiting for.

I will make further tests while walking but I’m ease that it is not a hardware problem.

A last word, as you probably seen with my poor english, I’m not a native english speaker, could you explain me with first age words what did you mean with “time-to-first-lock” ? Is-it when I said that the position remains the same even when moving ? If it’s that, those to first tests are conclusive. Of course, I will continue and update this thread, especially if it goes wrong again.

Hi Edrae,

Sorry you are having issues. We’ve made some post-R1.4.3 udpates to the GPS stack. Here are the instructions to upgrade (thanks to jconnolly)

We’ve rewritten a significant portion of the GPS stack to use a more widely adopted open-source JSR179 API.  The changes should be transparent at the App level, but you should note a significant increase in reliability at the API level.  This won’t impact the Time-to-first-lock problems, but hopefully will address the other GPS woes you’ve had.

Instructions:

1. Boot BUG with connection to internet (ethernet, wifi)
2. Get to command line (ssh or serial)
3. wget http://repo.buglabs.net/ipkg-extras.conf -O /etc/ipkg/ipkg-extras.conf
4. ipkg update
5. ipkg install http://repo.buglabs.net/all-extras/com.buglabs….
6. ipkg install http://repo.buglabs.net/all-extras/com.buglabs….
7. ipkg install http://repo.buglabs.net/all-extras/com.buglabs….
8. Reboot.

Please let us know if you still have issues.

Thanks,

Brian

Hi Tirumal. 

Have you looked at the tutorial for building angstrom?  Then it’s simply a matter of

bitbake openjdk-6-cacao; bitbake jamvm; etc.

http://code.google.com/p/beagleboard/wiki/HowTo…


The only problem is that theses are not available in oe.dev but in jalimo overlay

The howto are located here:

http://wiki.openembedded.net/index.php/Java is for an explanation of the different javas

https://wiki.evolvis.org/jalimo/index.php/Build… is the howto

Topic: BUGmodules / BugLocate / GPS : moving is bad.

Hello,

When I let my GPS static, his accuracy is good, it retreives the position. But when I’m moving, It stops retreiving position or give me always the same position. It’s appears when I’m walking as well as driving a car. Speed dosen’t seems to be the problem.

I tries many ways, for exemple parsing NMEA datas directly from RawFeed but it doesn’t improved anything.

Did someone get a return on his BugLocate accuracy and updating position ? Is it an antenna problem (with passive antenna, accuracy is worst but it seems to be normal) or a module problem ?

Thanks,

    Edrae.

Hi jconnolly,


Thank you for the reply.

I am have read the tutorial for building angstrom but some how couldn’t not build the targets correcty. Now, am able to build cacao, jamVM, phoneme-advanced personal profile correcty and resulting in .ipk files which I installed manually on target platform (Beagleboard) using Opkg tool.

I have also tested it with my HelloWorld java program successfully. But I wasn’t able to run java application using swing module. Can you throw some light on it??

 

Best wishes,

Tirumal

Department of homeland security might be a source of significant funding…


I found this news story about how DHS is developing a small chemical sensor chip for mobile cell phones


http://www.dhs.gov/files/programs/gc_1268073038…


I suggest you talk to DHS and Qualcomm, The bug could beoume a platform for early testing and deploying of this sensor. they are developing.

Dear Mr Schultz,

Thanx for the benchmarking article.

I am interested in PhoneME, Cacao/OpenJDK flavours on Beagleboard
with Angstrom distribution. Can you please provide more information/how
to get this cross-compiled on ubuntu.


Did you use jamilo VM’s?

thanx  in advance!

Best wishes,



Tirumal
