Outputting LoRaWAN data as PCAP

Description

This uses LoRa packet forwarder to forward the LoRa packets to a localhost with port 1700. Once packet forwarder is running, another process executes tcpdump that captures a loopback interface and outputs it as a pcap file. Afterwarads, we remove the Ethernet, IP and UDP headers (14+20+8) of the pcap file and set linktype to user (147). Finally, the edited pcap file is loaded to Wireshark, where the protocol is changed to LoRaWAN.

Instructions

Users should flash the correct configuration of LoRadar on the microSD card ` sudo apt-get update -y sudo apt-get install -y bittwist sudo apt-get install -y tcpdump

sudo tcpdump -s 0 -AUq port 1700 -w trial.pcap bittwiste -I trial.pcap -O dump_dlt_user.pcap -M 147 -D 1-42`
