Hi everyone, I’m trying to build a pure Wi-Fi Direct scenario in Mininet-WiFi (Python 3.8, mininet-wifi==2.6, Ubuntu 20.04). Even with two stations placed only a few metres apart, they never discover each other and ICMP fails.
Here's the log:
```
sudo python mn_wifi/examples/wifiDirect.py

```

Is the network manager running?

I have tried to stop network manager with sudo systemctl stop NetworkManager but stations still cannot reach each other.
Is the command enough to stop network manager?

I just updated wifi direct with this patch:
https://github.com/intrig-unicamp/mininet-wifi/commit/a6c09958abb96de7411527094c42f8464154ba68

For some unknown reason, wpa_supplicant throws an exception when using
p2p_connect auth. This is likely a bug or unexpected behavior in the
implementation.
