Introducing the detailed information of the ed-clte V2.0.4 version.

1.1 Version Overview

  • Version Number: V2.0.4
  • Release Date: 2026.09.23
  • Release Type: Stable Release
  • Prerequisite: Upgraded from V2.0.3

1.2 Version Upgrade Description

This release primarily fixes known issues found in previous versions and includes optimizations and enhancements to certain features.

1.3 New Features

  • Multi-target online detection: Online detection addresses adjusted to 8.8.8.8, 1.1.1.1, 223.5.5.5, 114.114.114.114, with support for user-customizable detection addresses.
  • User-defined detection scripts: Users can write custom scripts for network connectivity checks.
  • Automatic network priority switching: When a higher-priority network interface becomes unavailable, the system automatically switches to the next available network; when the higher-priority interface recovers, it automatically switches back.

1.4 Optimizations

  • Persistent reconnection during long 4G reset intervals: Continuously monitors 4G network status and attempts reconnection during extended module reset intervals, reducing downtime.
  • Improved firmware package naming: Optimized the naming convention for 4G module firmware packages for easier version identification and batch upgrade management.

1.5 Issue Fixes

  • Fixed unstable 4G module IP acquisition: Resolved intermittent IP loss or failure to obtain a new IP address.
  • Fixed network priority management anomaly: Corrected boundary condition errors in the priority switching logic to ensure expected behavior.
  • Fixed device disconnection when WLAN is turned off: Fixed an issue where the default route failed to fall back to wired or 4G networks after turning off the wireless network, causing complete device disconnection.
  • Optimized 4G online detection mechanism: Removed the single dependency on ping edatec.cn and replaced it with multi-target probing for improved detection stability and reliability.
