[Openbts-discuss] The code for OpenBTS based on one WBX daughterboard attached

[Robin C. <co...@cl...>]

As you've noticed, the WBX uses a different synthesizer from the
RFX900/1800 boards, the ADF4350 instead of the ADF4360.   This chip
has five 32 bit configuration registers instead of three 24 bit
registers.  Using the _write_spi function with the WBX board may be
the problem.  (I must confess that I don't have a clue what you're
trying to do with that write_it function and don't have a WBX board,
so can't run any helpful tests.)

In the gnuradio-3.2 source code, take a look at
gnuradio-3.2/usrp/host/lib/db_wbxng_adf4350.cc and
db_wbxng_adf4350_regs.cc.   As Thomas suggests, try replacing those
hacked-up _write_spi calls with the appropriate libusrp wbx functions
to set the Tx and Rx frequency and enable the RF chains.
