![5 WPS – WI-FI PROTECTED SETUP Simple Config Architectural Overview This section presents a high-level description of the Simple Config architecture. Much of the material is taken directly from the Simple Config specification. Figure 1 depicts the major components and their interfaces as defined by Wi-Fi Simple Config Spec. There are three logical components involved: the Registrar, the access point (AP), and the Enrollee. The Enrollee is a device seeking to join a WLAN domain. Once an Enrollee obtains a valid credential, it becomes a member. A Registrar is an entity with the authority to issue and revoke domain credentials. A registrar can be integrated into an AP. The AP can be either a WLAN AP or a wireless router. Figure 1. Components and Interfaces Registration initiation is ordinarily accomplished by a user action such as powering up the Enrollee and, optionally, running a setup wizard on the Registrar (PC). 5.1 Iwpriv use This section describes parameters set using iwpriv. Please refer to the Readme section for more general data. iwpriv ra0 [commands]=[Value] Note: Wireless extension private handlers. 5.1.1 wsc_conf_mode Set WPS conf mode. Range: {0, 1, 2} Value: 0: WPS Disabled 1: Enrollee 2: Registrar 5.1.2 wsc_mode Set WPS mode, PIN or PBC.

Range: NULL Value: 5.1.7 wsc_stop Stop WPS process and don't wait upon two-minute timeout. Range: NULL Value: 5.1.8 wsc_gen_pincode Generate new PIN code. Range: NULL Value: 5.1.9 wsc_cred_count Set count of WPS credential, only support one credential for M8 in Registrar mode. Range: {1 ~ 8} Value: 5.1.10 wsc_cred_ssid Set SSID into credtentail[idx].
