LoRa RN2483

Intro

In this repo, we will show how to use RN2483.

  1. P2P
  2. Gateway
  3. File Transfer

Environment

Two sets of Raspberry Pi 3B/3B+ + SanDisk 32G microSD + RN2483 + 2018-06-27-raspbian-stretch.img

Prerequisite

Install required package and Python module

$ sudo apt-get update
$ sudo apt-get install -y samba samba-common smbclient samba-common-bin smbclient cifs-utils python-dev python-pip libpcap-dev libnet1-dev vim sqlite3
$ sudo pip install flask requests pysmb
