I want connect two raspberry pi 4B by using p2p. Then i am using wpa_supplicant to set up p2p. However, after i finished set up the wpa_supplicant.conf and run wpa_supplicant sucessful. The wpa_cli still cannot find other raspberry mac address. Here is my wpa_supplicant at /etc/wpa_supplicant/supplicant.conf raspberry pi 1:
ctrl_interface=DIR=/var/run/wpa_supplicant
update_config=1
device_name=Terminal-1
device_type=1-0050F204-1

raspberry pi 2
ctrl_interface=DIR=/var/run/wpa_supplicant

Then I run
sudo systemctl stop NetworkManager
sude killall wpa_supplicant
sudo systemctl disabble NetworkManager
Then type
wpa_supplicant -Bd -iwaln0 -Dnl80211 -c /etc/wpa_supplicant/wpa_supplicant
and show
wpa_supplicant v2.9

However, it's cannot show other pi mac address.
Is anyone know to solve it. or is there any way to do p2p? Can anyone help me or provide useful methods
