+LBJ Console 是一个应用程序，用于通过 BLE 从 [SX1276_Receive_LBJ](https://github.com/undef-i/SX1276_Receive_LBJ) 设备接收并显示列车预警消息，功能包括：
 
 - 接收列车预警消息，支持可选的手机推送通知。
 - 监控指定列车的轨迹，在地图上显示。
 - 在地图上显示预警消息的 GPS 信息。
 - 基于内置数据文件显示机车配属，机车类型和车次类型。
-- [WIP] 从 RTL-TCP 获取数据。
+- 连接 RTL-TCP 服务器获取预警消息。
 
 [android](https://github.com/undef-i/LBJ_Console/tree/android) 分支包含项目早期基于 Android 平台的实现代码，已实现基本功能，现已停止开发。
 
+本项目为个人业余项目，代码质量和实现细节可能不尽如人意，敬请见谅。

 ## 数据文件
 
 LBJ Console 依赖以下数据文件，位于 `assets` 目录，用于支持机车配属和车次信息的展示：
