O_K210_WifiLte远程抓拍图传
问题
- 4G AT流程太慢，鉴于稳定性优化空间也有限，所以考虑在Air724UG单独做一套代码，用并行IO进行命令传递。
- 从整体功耗和响应速度来说最好还是再加一片单片机进行主要逻辑工作，控制Wifi/Lte的电源使能。目前ESP32S开机时间太长，不适合快速响应的超低功耗方案。
- Wifi的save_power模式待测试。
- 串口发送Hex数组由于0x00的原因用strlen()与sizeof()均无法得到正确的长度，所以只能指定发送长度。
- 主体task还有优化空间，现在按 1024 的接收最大长度和 1024*4 的堆栈大小正常剩余空间为2000左右，但瞬间接收到大量无效字符串后还是会导致Core dump，具体是不是堆栈溢出还有待验证，不过这个问题必须要解决。
- 目前临时服务器可进行Wifi/Lte切换，Wifi账号密码理论可实现。
- 监视任务堆栈大小及其它调试信息在app_main()中调整各LOG标签的级别即可。
