[gpsd-users] Shared memory 'flags' set?

[Michael Lum]

Hi,

 

I'm using the source for gpsd 3.17 and everything works fine using the socket interface with C++ on CentOS 7.

I'm using a Ublox NEO-7 receiver.

 

Using the socket interface I see:

 

TIME

LATLON

ALTITUDE

SPEED

TRACK

CLIMB

STATUS

MODE

SKY

 

However, when I try to use the shared memory interface only a few of the flag fields are set.

 

I see:

 

ONLINE

STATUS

DOP

SKY

 

 

This looks like the same question posed in gpsd-dev:

 

http://lists.nongnu.org/archive/html/gpsd-dev/2016-10/msg00017.html

 

But there are no responses to that thread.

 

Does anybody have any ideas about what is happening?

 

 

PS

 

STATUS is always coming back =1 for shared memory but =2 when I use the socket interface.

The same machine, antenna, with a simple service restart in between.

 

 

Best regards,

 

Michael
