"Wireless Made Easy!" - This example application acts as a bridge to bridge up WiFi and ETH interface of WFI32 device, WFI32 set as Wi-Fi Station(STA) mode to connect to Access point(AP). The WFI32 device help connect ETH end node to the Access point (AP) in this example.
Devices: WFI32E01
This application demonstrates how a ETH end node can connect to a WiFi network through WFI32 device. The WFI32 device is set as Wi-Fi Station (STA) mode to connect the Accesss point (AP) and act as a Wi-Fi ETH bridge to bridge up the Wi-Fi and Ethernet interface. In the setup, ETH end node connect to the Ethernet connector of WFI32 device and exchange data with the Access Point through the WFI32 device. The user would need to configure the Home AP credentials (like SSID and security items). The Wi-Fi service running on WFI32 device will use the credentials to connect to the Home AP.The default application will try to establish a connection to AP "DEMO_AP" with WPA2 security and password as a "password".
This project process the IP packets that received from the Wi-Fi and ETH interface at bridge.c. The code in this file act as a transparent bridge to receive and forward the network packets to and from both Wi-Fi and ETH interface. It set the mac address of WFI32 to be the same as Ethernet end node so that the Ethernet end node can communicate with the AP. As both Ethernet end node and WFI32 are using the same mac address, they are acting as a single unit in the network.
The H3 L2 Bridge feature is not used in this project

During the code generation, keep below change for the bridiging application code , no need to merge with the new code
-
Save configurations and generate code via MHC
-
Build and program the generated code into the hardware using its IDE
-
Open the Terminal application (Ex.:Tera term) on the computer
-
Connect to the "USB to UART" COM port and configure the serial settings as follows:
- Baud : 115200
- Data : 8 Bits
- Parity : None
- Stop : 1 Bit
