Hello,

I'm running gr-ieee802.11 on a Raspberry Pi 3 running Raspbian. I'm
connected to a bladeRF and running GRC 3.7.10. At this point, I want to
sniff WiFi packets to demonstrate the bladeRF working with receiving WiFi
from say a router or laptop (no transmission yet). I'm using the 2.4GHz
band with 20MHz bandwidth because bladeRF does not go up to the 5GHz band.

In the WiFi RX example, I only changed the USRP Source to a Osmocom Source
block. In this example, it appears Wireshark has been connecting to GRC via
the /tmp/wifi.pcap pipe because the Wireshark capture session closes when I
kill the WiFi RX script. The constellation and time graphs both work, but I
do not see any packets in Wireshark no matter the channel. Executing the
script produces no errors, it just doesn't capture packets.

I thought the FFT block might be to blame because it had no documentation
for it while all the other blocks did. I reinstalled fftw3 (v. >3) and it
didn't update the documentation. osmocom_fft also works, so I don't think
the FFT block is the problem but I wonder why it's missing documentation.
Then, I reinstalled gnuradio and gr-ieee802.11 both after making sure the
necessary dependencies were met for both. Still no changes. Wireshark
receives packets from the WiFi Loopback example sent by the message strobe
perfectly fine.

I would greatly appreciate any insights you have into why Wireshark is not
receiving any WiFi packets from the bladeRF using the WiFi RX example. Do
you have any ideas of what's going on or would you need any more
information?

Thank you,

Eric Yates
