The Smart Config is a method to allow the WLAN device to be connected to the network without having to configure the AP information on the device. This method is required for devices without a GUI or keyboard. The main target of the procedure is to receive (over the air) the SSID and password of the AP that the device should connect to, from a third-party device. Once the device gets these parameters, it connects to the AP and obtains an IP address.
Use a third-party device to deliver the network parameters (SSID + password). Enter the WLAN device into Smart Config mode by either pressing a button or simply turning on the device; the device then moves to Sniff mode.
The third-party device periodically transmits a SYNC pattern interlaced with the encoded SSID + password of the AP. The WLAN device scans all channels, searching for the SYNC pattern. Once the WLAN device finds the SYNC pattern, it tunes to the specific channel the pattern was found on, and starts receiving the SSID + password. Once done, the device exits Smart Config mode and connects to the requested network with the SSID + password.
