Wi-Fi Hostspot (SoftAP)

TI-Android-ICS-4.0.3-DevKit-3.0.1 supports Wi-Fi hostspot (SoftAP) feature with TI WL1271 Wireless module.

• To turn on Wi-Fi hotspot, browse to "App Launcher" -> "Settings" -> "More..." -> "Portable hotspot"

• Click "Configure Wi-Fi hotspot" to configure the hotspot settings..

Note: Do not enable Wi-Fi Hotspot before configuring the settings. Changing the settings after enabling Wi-Fi hotspot may result in hotspot malfunction

• Click the checkbox next to "Portable Wi-Fi hotspot" to start hotspot. You will see the message "Tethering or hotspot active" in the notification bar once the hotspot is fully functional.

• The following screenshot shows the hotspot being detected from another evm.

Note: Tethering with another network interface like ethernet is not currently supported in this DevKit release

Wi-Fi Direct

TI-Android-ICS-4.0.3-DevKit-3.0.1 supports Wi-Fi Direct with TI WL1271 Wireless module.

• To turn on Wi-Fi direct, browse to "App Launcher" -> "Settings" -> "More..."
• Click checkbox next to "Wi-Fi direct".

• After Wi-Fi direct is enabled, click "Wi-Fi direct: Set up peer-to-peer connections". This window shows any nearby devices with Wi-Fi direct enabled.

Note: Wi-Fi station mode or SoftAP/hotspot mode, if enabled, shall be disabled when Wi-Fi direct is active. The earlier state is restored when Wi-Fi direct is disabled

Changing WLAN MAC Address

The devices loaded with TI-Android-ICS-4.0.3-DevKit-3.0.1 will have the same MAC address which is encoded in wl1271-nvs.bin file. This may result in Wi-Fi not operating correctly when multiple devices are simultaneously in use. For optimum results, we recommend to modify the MAC address to ensure unique MAC for the devices before use

Note: Ensure that Wi-Fi (STA mode), hotspot (SoftAP) or Wi-Fi direct is not enabled when you are changing the MAC address

To change the MAC address, perform the following on the serial console of device:

• First get the current MAC address for WLAN:

  root@android:/ # calibrator get nvs_mac /system/etc/firmware/ti-connectivity/wl1271-nvs.bin

• Then update the MAC address for WLAN:

  root@android:/ # calibrator set nvs_mac /system/etc/firmware/ti-connectivity/wl1271-nvs.bin <MAC Address>

You need to reboot the board after changing the MAC address.
