Re: [Discuss-gnuradio] Control Port : Ctrlport Key called with unregistered key

I re-installed UHD drivers, GNU Radio as well as gr-foo and gr-ieee80211 . I started to run the transmitter with Performance Monitor but got the following error:

ctrlport-monitor: radio.get threw exception (math domain error).

I tried looking for an explanation online but was unsuccessful. Any ideas to the reason for the error. I am pretty sure it is not related to gr-ieee80211.

Specs:

GNU Radio - 3.7.3

UHD Driver - 3.7.1

RF Front-End - NI USRP- 2920

OS - Ubuntu 12.04

I just reran the example and it works for me, but maybe you can run the performance monitor for a simple flow graph with GNU Radio blocks only, just to assure that the error is not related to the 802-11 stuff...


Best,
