ECM50-A Multi-Network Networking Case

This document serves as the case showcase entry from the project overview. Complete wiring, configuration, networking verification and troubleshooting steps will be added later.

Case Overview

This case targets the ECM50-A industrial device, planned to cover three networking methods: 4G cellular network, W5500 Ethernet and WiFi, and explain network switching, platform onboarding and field deployment verification procedures.

Planned Content

• Device interface and antenna installation instructions
• 4G SIM card, APN and signal check
• W5500 Ethernet wiring and network parameters
• WiFi provisioning and priority strategy
• Platform online status and link switching logs

Temporary Verification Steps

1. Check power supply, antenna, Ethernet cable and SIM card status.
2. Flash the ECM50-A corresponding firmware.
3. Verify WiFi, Ethernet and 4G networking separately.
4. Confirm the current network channel in serial console logs.
5. Confirm device online status and data reporting on the platform.
