The XDK Wi-Fi API is a part of the XDK platform section and accesses the Texas Instruments Simplelink Library that is part of the library section. The Simplelink library provides a low level access to the CC3100 Wi-Fi chip of the XDK-Hardware.

This section will demonstrate some functions of the two main APIs for Wi-Fi. Those are

• BCDS_WlanConnect.h

  for the Wi-Fi connection interface

• BCDS_NetworkConfig.h

  for the Wi-Fi configuration interface

The BCDS_WlanConnect.h interface provides several functions to make the Wi-Fi Hardware available and to do things like searching for networks or initiating a connection to them. In general, this interface provides the connection functions of the API.

Function	Description
WlanConnect_init()	Initialize Wi-Fi driver and Wi-Fi stack. This function must be called before calling any other Wi-Fi API function
WlanConnect_DeInit()	Deinitialize the Wi-Fi driver and the Wi-Fi stack
WlanConnect_ScanNetworks()	Scan for surrounded Wi-Fi networks
WlanConnect_Open()	Connect to a network without security permissions
WlanConnect_WPA()	Connect to a network with a WPA passphrase
WlanConnect_Disconnect()	Disconnect the current network connection
WlanConnect_CurrentNwStatus_T()	Delivers the current status of the Wi-Fi network connection

The BCDS_NetworkConfig.h interface provides basic functions to make general connection settings and to get informations about the current network connection.

NetworkConfig_Ipv4Value()	Convert a given IP in a hexadecimal state
NetworkConfig_Ipv4Byte()	Extract a byte from an acquired IP address
NetworkConfig_SetIpStatic()	Set the configuration to a static IP
NetworkConfig_SetIpDhcp()	Set the configuration to dynamic IP by using DHCP
NetworkConfig_GetIpSettings()	Handle Wi-Fi IP settings. Return a structure that includes the connection information
