LoRa无线通信
基于STM32F103C8T6的LoRa模块通信,使用ZLG的SX1276方案，SX1276/77/78 收发器主要采用LoRaTM 远程调制解调器，用于超长距离扩频通信，抗干扰性强，能够最大限度降低电流消耗。借助升特的LoRaTM 专利调制技术，SX1276/77/78 采用低成本的晶体和物料即可获得超过-148dBm 的高灵敏度。此外，高灵敏度与+20dBm 功率放大器的集成使这些器件的链路预算达到了行业领先水平，成为远距离传输和对可靠性要求极高的应用的最佳选择。相较传统调制技术，LoRaTM调制技术在抗阻塞和选择性方面也具有明显优势，解决了传统设计方案无法同时兼顾距离、抗干扰和功耗的问题。

0. Install the rp-pppoe-software
--------------------------------
You should have already done this by the time you re reading this. If not,
go back and read README.
1. Set up your Ethernet hardware
--------------------------------
First, make sure the Ethernet card you intend to use with the modem is
visible to the Linux kernel. Just how to do this is beyond the scope
of this document. However, if the card is the only Ethernet card in
the system, executing:
ifconfig eth0
should display something like this:
eth0 Link encap:Ethernet HWaddr 00:60:67:62:31:D4
plust some more lines. Your HWaddr will be different. As long as you see
the HWaddr line, your card should be working.
DO NOT assign an IP address to the Ethernet card. DO NOT configure the
card to come up at boot time.-0. Install the rp- PPPOE-software-------------------------------- You should have al ready done this by the time you re reading this. I f not, go back and rea
