[Discuss-gnuradio] Unexpected wifi_loopback.grc output

[Gupta, Arjan]

Dear list,

I am trying to set up a transceiver in GNU Radio. I have downloaded and installed Bastian Bloessl's repos by following his instructions on

https://github.com/bastibl/gr-ieee802-11.

Here are my system details:

• OS: Ubuntu 14.04.1
• GNU Radio version: 3.7.9.2

Since I just installed this, I am just trying to get wifi_loopback.grc to execute properly, but I have strange output. I have tried to fiddle around with the snr, pdu length, pdu interval, but my output does not have the decoded "Hello World" packets that it should.

Here is the output the output for the flow graph:

When I generate the flow graph for wifi_loopback.grc, it gives me the output:

-----

Generating: '/home/student/bastibl/gr-ieee802-11/examples/wifi_loopback.py'
>>> Warning: This flow graph may not have flow control: no audio or RF hardware blocks found. Add a Misc->Throttle block to your flow graph to avoid CPU congestion.

Is it supposed to be this way or am I doing something wrong? Any help would be really appreciated.

Best regards,

Arjan Gupta
