Test_usrp_inband_rx and setting frequency

Hi,

i am trying to change the frequency in the test_usrp_inband_rx of the
the apps-inband directory of the svn.
So i added to test_usrp_inband_rx.cc the lines

long myfreq;
pmt_dict_set(usrp_dict,
pmt_intern(“rf-freq”), pmt_from_long(myfreq) );

before
define_component(“server”, “usrp_server”, usrp_dict);

in the constructor.

if i set myfreq=44000001 test_usrp_inband_rx fails to connect to the
usrp (failed to open usrp:(() #f)status = #f)
but not with myfreq = 44000000 which is 44mhz although i got a RFX1800
daughterboard
which should not work with frequencies lower than 1.8Ghz?

Is myfreq to be meant in Hz ?

Am i missing something or is there maybe something broken in the
usrp_server?

Greetings,
Axel

The inband signaling work only supports the BasicTX/RX daughterboards.
It’s pending on C++ daughterboard support.
