Hi,

This is expected behavior if the device is doing power save flows with the AP, or just sending a keep alive.

Subject: NULL function frame

I sniffed data with wireshark from wpa_supplicant. I recongnized that wpa_supplicant sends almost every second  a NULL function frame to my AP.

I that behavior normal?


Thios is config file:

# Plaintext (no encryption) network
ctrl_interface=/opt//hostapd/hostapd-2014-06-03/wpa_supplicant

network={
    ssid="OpenWrt"
    key_mgmt=NONE
    bgscan="simple:5:-70:10"
}
