The module’s innovative design integrates all necessary hardware and software resources for Wi-Fi and Bluetooth applications. This high level of integration ensures efficient operation across scenarios, reduces reliance on external components, and lowers development complexity and costs.

The EWM103-W15 series supports two Wi-Fi operating modes: AP (Access Point) and STA (Station), offering unparalleled flexibility:

• AP Mode: Acts as a wireless router, allowing other devices to connect to its created network for peer-to-peer communication.

• STA Mode: Connects to existing wireless networks, facilitating internet access or communication with other networked devices.

This dual-mode switching capability adapts to diverse needs in homes, offices, and industrial environments.

Low-Power Design to Extend Device Lifespan

For battery-powered devices, power consumption is critical. The EWM103-W15 series excels in this area, with a current consumption of only 20 microamps in low-power mode. This ultra-low power draw significantly extends device lifespan, reduces battery replacement frequency, and lowers operational costs. It is particularly ideal for power-sensitive applications such as smart sensors and wearables, ensuring long-term stable operation and enhanced user convenience.

Multi-Device Access and Seamless Cloud Integration

The module supports AP functionality, enabling simultaneous connections with up to 3 STA devices, meeting multi-device access requirements. In smart homes, users can connect multiple devices (e.g., smart bulbs, sockets, door locks) via a single EWM103-W15 module for centralized management and control.

Additionally, the module supports the MQTT protocol, enabling seamless integration with mainstream IoT platforms like Alibaba Cloud, Baidu Cloud, and OneNet. MQTT, a lightweight publish-subscribe messaging protocol, is optimized for low bandwidth, low power, and high reliability—perfect for IoT applications. This integration allows easy uploading of collected data to the cloud for storage, analysis, and remote monitoring, providing users with convenient cloud service access.

Diverse Protocols to Meet Varied Needs

The EWM103-W15 series supports multiple network protocols, including TCP, UDP, SSL, and MQTT, offering versatile options:

• TCP: A connection-oriented, reliable protocol for scenarios requiring high data accuracy.

• UDP: A connectionless, fast protocol with low overhead, suitable for real-time applications.

• SSL: Provides encrypted communication to ensure data transmission security.

• MQTT: Ideal for lightweight IoT communication, as highlighted earlier.

Whether for secure encrypted communication, high-efficiency real-time data transfer, or lightweight IoT connectivity, the module delivers optimal performance.
