Silver Care IoT

MVP for an elderly-care smart watch IoT platform.

Current focus:

• Backend first
• TCP long-connection device gateway
• Protocol parsing for LK, UD, UD2, AL, btemp2, bphrt
• Device, health, location, alarm, and raw packet data model
• REST APIs for future Web and mini-program clients

Backend

Planned stack:

• Java 21
• Spring Boot
• Spring Web
• Spring Data JPA
• MySQL

Run after installing JDK and Maven:

cd backend
mvn spring-boot:run

Admin APIs under /api/admin/** use HTTP Basic authentication. The Web client asks for the credentials at login time and keeps them only in the current browser session. Configure credentials before starting:

SILVER_CARE_ADMIN_USERNAME=...
SILVER_CARE_ADMIN_PASSWORD=...
SILVER_CARE_DB_PASSWORD=...
WECHAT_MINIAPP_APP_SECRET=...

See docs/deployment.md and .env.example for the complete deployment checklist. The mini program uses WeChat wx.login, server-side sessions, and per-user device bindings; its AppSecret belongs only on the backend server.

Default ports:

• HTTP API: 8080
• Device TCP gateway: 9001
