Has anyone been able to work the protocol sniffer with the 2510 and 2511 radios?

I am following the settings and recommendations in the documentation in order to use SmartRFStudio connected to a SmartRF40EB board with a cc2510 and the Packet Sniffer using a ccDebugger and an CC2511 as the capturing device.  I exported the register setting for the CC2511 using Studio and use that prs file in the sniffer.  Every time I try running the sniffer I get different errors and has not worked so far.
