Re: [Discuss-gnuradio] Blank display in control port performance monitor in gr-ieee 80211

[Sumit Kumar]

The same happens while running gr-ieee-802-15-4 too :-/ 

They were working smoothly a couple of months back :(

Hi, 

I am running wifi_rx and I put 

CtrlPort Performance Monitor and CtrlPort Monitor block in the flow graph. 

I don't see any thing on the Ctrl Performace Monitor. Its blank. 

Image attached.

I remember I did the same experiment a couple of months back and it worked. 

Also whenever I click any button on the blank display of Ctrl Performace Monitor, I see following warnings 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

ControlPort Monitor running.
