[ipxe-devel] [ipxe/ipxe] QRcode (#102)

[dgtlrift]

> neat/ I started to look at generating a QRcode server side and passing it down in a chain loaded ipxe script in a retry loop. The QRcode brings user to a webpage to enrol the system. Looks like i'll just continue with my hack for now.

I'm getting off topic, but I would strongly recommend taking a look at DPP (device provisioning protocol) mentioned above - first it's ratified as a standard by the Wi-Fi Alliance (albeit an optional feature) but it preferred over PBP (push button provisioning) and WPS (Wi-Fi protected setup) because of the UX, security, and failure mode handling, support has been added to the w1.fi wpa_supplicant project, it supported by Android (albeit current only with the google pixel.)
It is a standard secure way to onboard devices and it's only a matter of time before all the Wi-Fi transceivers in Androids and iPhones support the configurator mode information elements of 802.11 needed for DPP.
