Re: [gpsd-users] GPSD 3.6 and uBlox Neo7M

[Cuningan Re Set]

Hello Gary, thanks for your help.

The GPS was in nmea mode before starting gpspipe -r and when i try to change it to ublox binary mode with #gpsctl -b it fails, said that can not be done, sometimes said that are multiple subscribers ( i don't know why but it said).

But, after two days i have good news, i remove the Raspbian gpsd install (#apt-get remove gpsd), Raspbian comes with gpsd version 3.6 ( older version)

I start from scratch downloading sources for gpsd 3.15 and try to build it, first i need "scons", i install (#apt-get install scons) but after install i dont have the correct version of scons ( scons needed to be version 2.3 and i have 2.1 ), seems like Raspbian has very old packages.

Finally build from from sources gpsd version 3.14 (that build with scons < 2.3 ) and now when run it detects my GPS as uBlox and i can change it to binary mode using #gpsctl -b.

The gps is a breakout board for arduino i am adapting to Raspberry Pi, with chipset Neo 7 M.

Thanks for your help, i have the intention to write a how to compile gpsd for the Raspberry Pi from a stock Raspbian distro, i didn't found a good tutorial for this, thanks to the build.txt file that comes with the sources i managed to build.

As you sure has note i am not an expert in linux.

Thanks a lot for your help.

Cool.  What GPS?

As expected.  If you want the uBlox in binary mode you need to use
'gpsdctl -b /dev/ttyAMA0' to make it so.

Do you have a good reason to want uBlox mode?

Was the GPS in uBlox binary mode before starting gpsd?
