How can I know which USRP is installed GPS?

Hi

My PC is connected with 2 USRPs and one of them is connected with GPS
and
the other one is using the MIMO cable to share the GPS.
My question is, is it possible to use the Python code to detect which
USRP
is equipped with GPS, and which is not?

Thanks,

Alex,

There are a few things you can query:

  1. the sensors list will have new things in it like gpsdo_locked, and
    nmea strings:
    http://files.ettus.com/uhd_docs/manual/html/gpsdo.html#using-the-gpsdo-in-your-application

  2. The available time and clock sources list should also include gpsdo
    (on the master branch)

Both of these things should be exposed in the python source/sink blocks.
