DPP Pixel Enrollee

Hi,

I'm trying to use DPP to onboard a Pixel using a Raspberry Pi 3b+.

DPP bootstrapping and authentication succeed, but I'm having trouble
setting a configuration for the Pixel enrollee. Hostapd is rejecting
the configuration request.

DPP Logs:

Specifically this line is the problem: DPP: No configuration available
for Enrollee(sta) - reject configuration request

I'm using version: 2.8-devel.

hostapd.conf:

interface=wlan1
driver=nl80211
ctrl_interface=/var/run/hostapd
ssid=test
channel=1
wpa=2
wpa_key_mgmt=DPP
#ieee80211w=1
wpa_pairwise=CCMP
rsn_pairwise=CCMP


Any help would be appreciated. Is it currently possible to onboard a
Pixel this way?

Thanks,

Wystan
