Benefits of Wi-Fi Bridging
Bridging solutions connect multiple networks that use the same or different protocols by aggregating them into a single network. For example, an Ethernet-to-Wi-Fi bridging device receives incoming data from an Ethernet network and sends it back out via Wi-Fi and vice versa.
In general, Wi-Fi bridging is the fastest and easiest way to enable a Wi-Fi connection on an existing host machine. It is an optimal solution because the host machine gains Wi-Fi access without needing any new software or drivers and while continuing to use its existing communication protocol such as Ethernet, CAN or USB.
Convert Ethernet, CAN or USB to Wi-Fi Using a Single Interface Module
The WFI32 is a unique Wi-Fi MCU module that boasts reliable performance in harsh environments while offering multiple communication protocols. These features make it a great candidate for Wi-Fi bridging in industrial applications.
A Wi-Fi MCU Built for Bridging
WFI32 Module Family
These all-in-one modules are high-performance, low power, 32-bit Wi-Fi MCUs with best-in-class peripheral sets and advanced security. They are well suited for bridging applications because they support connectivity options such as:
- Ethernet RMII
- Dual-CAN buses (CAN or CAN FD)
- USB
When paired with ready-to-use software examples and a robust development ecosystem, these modules make it easy to add Wi-Fi connectivity to a host machine or other device with existing Ethernet, CAN or USB connectivity.

Bridge LAN and Wireless LAN on a Single Network
In this application example, you will learn how to use the WFI32E as an AP to create a Wi-Fi bridge connecting multiple wired and wireless networks to create a single network.
What is Ethernet?
Ethernet is a type of computer networking technology that uses a standardized protocol to send and receive data packets over a physical network cable. It is one of the most widely used networking technologies, connecting devices such as computers, routers and switches together to form a Local Area Network (LAN). Ethernet operates at various speeds—including 10 Mbps, 100 Mbps, 1 Gbps and 10 Gbps—and supports a variety of cable types including twisted pair and fiber optic cables.
Enable Data Transfer Between CAN Nodes and Wi-Fi Peripherals
In this application example, you will learn how to bridge the CAN bus to Wi-Fi peripherals using a WFI32E device running in SoftAP Mode.
What is CAN?
Controller Area Network (CAN) is a type of computer network used in automobiles, industrial automation and medical devices. It provides communication between various MCUs and devices connected to the network and enables the exchange of data between them without the need for a host computer. CAN is designed for robust communication even in harsh environments and has features such as message prioritization, error detection and fault tolerance.
