LoRaWAN packet generator is a command line tool for generation of UDP packets that can be sent from the PC host to the LoRa Network Server. It simulates LoRaWAN gateway and sends the UDP packages defined by the "Gateway to Server Interface Protocol" defined in Semtech document ANNWS.01.2.1.W.SYS. Protocol is also described here.
Basically, lora-pktgen acts as a LoRa node + LoRa GW, i.e. it generates a package from a user-defined payload and adds service information in JSON that are injected by Packet Forwarder during the packet traversing through GW. This way LoRa Network Server get a properly shaped UDP packet, like the one that would come from a real HW.
lora-pktgen is used to test the LoRa Network Server deployments and integrations in the absence of expensive HW (gateways and nodes) and tedious HW network set-up.
If not set already, please set your GOPATH and GOBIN environment variables. For example:
mkdir -p ~/go
export GOPATH=~/go
export GOBIN=$GOPATH/bin
# It's often useful to add $GOBIN to $PATH
export PATH=$PATH:$GOBINUse go tool to "get" (i.e. fetch and build) lora-pktgen package:
go get github.com/mainflux/lora-pktgenThis will download the code to $GOPATH/src/github.com/mainflux/lora-pktgen directory,
and then compile it and install the binary in $GOBIN directory.
Now you can run the program with:
lora-pktgen
if $GOBIN is in $PATH (otherwise use $GOBIN/lora-pktgen)
