Greetings,
I'd like to add a vendor-specific Information Element to the Beacon and Probe Response frames.
=========================================================================
My hostapd.conf looks like this:
=========================================================================
interface=wlan0
# driver=nl80211 # doesn't matter if I choose nl80211 or the default, same behavior
logger_stdout=-1
logger_stdout_level=0
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=Test
country_code=CH
hw_mode=g
channel=6
vendor_elements=DD<length><oui><subtype><elements>
=========================================================================
Running on Raspberry Pi 3 Model B with the hostapd from apt-get:
=========================================================================
pi@raspberrypi:~ $ hostapd -v
hostapd v2.3
User space daemon for IEEE 802.11 AP management,
IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator
Copyright (c) 2002-2014, Jouni Malinen <j@xxxxx> and contributors
=========================================================================
The AP works fine (I can connect, but don't get an IP because I don't need DHCP -- I just want the vendor element in the beacon for now)
=========================================================================
pi@raspberrypi:~ $ sudo hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf

=========================================================================
When I check with Wireshark, the vendor element is not included in the beacons, though (OS X with sudo open Wireshark.app, and Monitoring on, while associated with the AP to monitor its channel).

I expect my additional vendor-specific element to be present in this list, but it's not.
How can I expose my vendor-specific Information Element to the Probe response and Beacon frames?
Thanks
Etan
