The hostap device is sending the authentication request on channel 1 - I have verified this using a wifi sniffer. As for the wpa_supplicant, I assume AP mode does not apply. I suppose it is possible that both supplicant machines (Pi & NUC) have wifi adapters that appear to support offchannel mode but do not. dpp_listen appears to work without errors. The Raspberry Pi (supplicant) is using a TP-Link Archer T4U V3 adapter. Given that hostap is sending out the authentication request on channel 1 and the wpa_supplicant logs show no receipt of management frames, anything you can think of for me to check? > On Feb 9, 2019, at 3:32 PM, Jouni Malinen <j@xxxxx> wrote: > > On Fri, Feb 08, 2019 at 03:10:29PM -0700, Steve Johnson wrote: >> I have built hostapd and wpa_supplicant per the instructions and am having trouble getting the negotiation to complete. Using wireshark (airtool), I can see that hostapd is sending the authentication request OTA. On the wpa_supplicant machine, I cannot see any nl80211 debug messages showing that any management frames have been received.
