For the gnuradio + usrp2 driver, there is a separate firmware image for WBX and XCVR2450. Which image did you use?

I met a problem for receiving signal by the USRP2-XCVR2450.

Already installed GNU Radio 3.3.0 and The latest firmware and Raw Ethernet
FPGA images have been written
onto the SDRAM: u2_rev3-20100603.bin, u2_rev3-20100603.bin.

I used usrp2_fft.py and the centre freq is 2.421G (I typed my bluetooth
keyboard quickly that would send many packets on frequence 2.421G). But the
usrp2_fft.py script shown only noise, none of the useful signal could be
received on my USRP2. Is there a USRP2-XCVR2450 receive problem while using
the latest firmware and raw ethernet FPGA code?
