I would be shocked if the Raspberry Pi 3 has the processing power to run gr-ieee80211. Are you attempting to do this real-time?

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?
