1.官方介绍
SLM770A是美格智能最新推出的一款LTE Cat.4无线通讯模组最大支持下行速率150Mbps及上行速率50Mbps。同时向下兼容现有的3G和2G网络以确保即使在偏远地区也可以进行网络通信。 SLM770A模组支持分集接收和MIMO技术优化数据传输的速度并提高通讯质量。支持NCM/PPP/ECM/TCP/UDP/DTSL/HTTP(S)/FTP/MQTT等多种拨号方式及内置网络协议。集成了UART/I2C/PCM/SPI/SDIO等丰富的硬件接口。广泛应用于工业路由、安防监控、CPE、车载DVR、共享等领域。
2.子端口说明
虚拟出来的各个子端口主要用来实现AT命令收发网络通信GPS诊断等功能。 二驱动移植与RIL适配
1.添加usb串口驱动
