GSM 850 Field Test Results

TEST HAS NOT STARTED

As many of you are aware the GTA01's GSM 850 is non-functional at this time. This test was designed by many in the OpenMoko community (thanks to Michael Shiloh) to rectify the situation. A GTA01 was modified and will be shipped around North America and the results will be posted here.

please comment well

   #Section to start and record re-playable GPS data !!!Information available to limited people!!
  
   exec /home/root/gllin/gllin & 
   cat /home/root/gllin/nmeaNP > /media/card/nmeareplay &
  
   # End GPS section
  
   #Section to record GSM signal quality !!Do math for QOS statistics!!
   #This Feature will be used to record signal quality ONLY no grep'ing for GSM commands 
   
   #End Section


Replaying the NMEA data can be done easily Just copy the nmeareplay file to your machine (/home/username/nmeareplay) in your GPS software change the gps port to the nmeareplay file (/home/username/nmeareplay)

When running, gllin creates a log file already, so nmeaNP doesn't need to be reflected to /home/root. Also, running for about two hours will fill the available memory. We need to record the log files on flash if we want to run for more than a few minutes. I do not know how to turn off the logging of the nmea0183 messages from gllin. On my device, I linked /home/root/gllin/logs to a logs directory on my removable flash. --Sagacis 08:52, 12 January 2008 (CET)
I think the logging should contain more information than just raw data. Something like the following, perhaps. --Sagacis 08:54, 12 January 2008 (CET)
LAT. LON, SIGNAL_STRENGTH, CARRIER NAME, TIME

The Executable

I've begun work on an openmoko gui application to display the information and log to a file. I may be done with it by 15 Jan 2008 if all goes well.

gsmd only gives us operator name, signal strength and connection status. We cannot currently get band or cell ID (to tell when switching towers).

Give it a shot and give me feedback. If anybody else wants to help out, I can make a project and share the code. --Sagacis 21:52, 12 January 2008 (CET)

Version 0.9 is available as source tarball and as ipk installer. --Sagacis 01:13, 14 January 2008 (CET)
