H&D Wireless AB, SPB209A Application Note page 2 ( 14) 1 Overview SPB209A is a complete WLAN/BT/NFC module with EMC shield, dual band antenna (WiFi and BT), prepared for application specific NFC antenna and ready for quick validation in a hosted environment. SPB209A-EVK has been used as an example in this User Manual. SPB209A-EVK features the SPB209A module mounted on a ready to run SD-card or SMD module for quick product turn-around or SPB209A evaluation.

It generates all required digital and analog supply voltages with the built in DC-DC converter. 2.1.1 Main supply The main power is connected to VDD. The ripple on VDD should be less than 10mV p-p. 2.
PAGE 4
H&D Wireless AB, SPB209A Application Note page 4 ( 14) Power save is an energy saving mode where SPB209A is only listening at regular intervals for the beacons transmitted from an access point and is set in sleep mode in between. During this sleep mode, firmware is kept in RAM but all not needed functions are turned off. Since the receive time is very short compared to the listening interval the average current consumption is reduced significantly.

PAGE 6
H&D Wireless AB, SPB209A Application Note page 6 ( 14) 2.8.2 STA operation using WPA Supplicant The wpa_supplicant is the IEEE 802.1X/WPA component used in the client stations. The WPA supplicant can be configured to control the roaming and IEEE 802.11 authentication/association of the SPB209A device. The configuration is usually performed in a configuration file, e.g. /etc/wpa_supplicant.conf. It is also possible to directly issue commands to the WPA Supplicant, using a dedicated shell command, wpa_cli.
PAGE 7
H&D Wireless AB, SPB209A Application Note page 7 ( 14) Note that the WPA Supplicant configuration can hold several networks and the WPA Supplicant will choose and roam amongst them. However, most importantly, the WPA supplicant implements the key negotiation with a WPA Authenticators. 2.8.2.

H&D Wireless AB, SPB209A Application Note page 9 ( 14) 2.8.2.4 Connect to a network that uses any WPA/WPA2 protocol and TKIP/CCMP encryption Note that several encryption parameters can be specified on a single line, allowing connections to a specific ssid using a range of encryption methods. The configuration file below should allow connections to the hdwireless access point regardless of whether the WPA or WPA2 protocol is used or whether CCMP or TKIP is used for pairwise and group key encryption.

Install Linux Wifi host AP package: sudo apt-get install hostapd 5. Plugin the sdio module. Make sure mwifiex driver was successfully started by typing: iwconfig mlan0 This command should display information about the mlan0 interface 6. mwifiex driver does not support ap mode on native interface, so an additional apdedicated interface must be created.
