Hi,
I want to use GPSDO in my application. Since there is no GPS antenna with
GPSDO-kit, I bought a 'SMA male straight GPS antenna'. Everything went well
before I connect the GPS antenna to the GPSDO. For example, I can receive
GPS time using usrp->get_mboard_sensor("gps_time"). Other uhd applications
also work well.
To lock to the satellite and update the GPS time, I connected the GPS
antenna to GPSDO. However, I got some weird errors. I even got the same
errors when I run 'uhd_usrp_probe'.
~$ uhd_usrp_probe
linux; GNU C++ version 4.4.5; Boost_104200; UHD_003.003.000-d5d448e
-- Opening a USRP2/N-Series device...

..
UHD Warning:

UHD Warning:

UHD Warning:

Error: ValueError: Timeout after no valid message found
Does anyone know how to fix it? I am using GPSDO+USRPN210+WBX on Ubuntu
10.04.
Thanks in advance.
Regards,
Jamie
