Note that SmartConfig is a TI-specific technology only available in the Spark Core (which is based off the popular CC3000 module). The Photon is based off a Broadcom chip and only appears to support Soft-AP provisioning (where the device presents itself as an access point that a phone/tablet/computer connects to in order to configure Wifi credentials.)
I'm excited to try out a Spark that isn't using the SmartConfig entirely because I'm unable to get it to connect to my WiFi network at work (running an enterprise WiFi setup using Cisco's APs)
