1 接入流程

1.1 概述

本文档是为了方便后续项目维护和管理、记录开发内容而创建。

本文档描述的OTA库是基于杰理的RCSP协议而实现。同时使用于单双备份的OTA流程。

1.2 导入说明

  • JL_Auth_x.x.x-release.har — RCSP认证库

  • JL_OTA_x.x.x-release.har — OTA库

  • JL_RCSP_x.x.x-release.har — RCSP协议库

1.2.1 导入SDK库

目前SDK文件是用一个Module lib_rcsp 统一管理，也可以直接放在App Module下。

Warning

在引用SDK库文件时，请注意不要修改依赖的module名称，会导致SDK内出错。

示例：正确引用

"dependencies": {
    "jl-ota": "file:./lib/JL_OTA_1.0.1-release.har",
    "jl-rcsp": "file:./lib/JL_RCSP_1.0.1-release.har",
    "jl-auth": "file:./lib/JL_Auth_1.0.1-release.har",
}

示例：错误引用(把 jl-ota 改为 jl_ota )

"dependencies": {
    "jl_ota": "file:./lib/JL_OTA_1.0.1-release.har",
    "jl_rcsp": "file:./lib/JL_RCSP_1.0.1-release.har",
    "jl_auth": "file:./lib/JL_Auth_1.0.1-release.har",
}
