Build JSON packet forwarder message for an uplink (rxpk)
npm install packet-forwarder-json-builder
Build JSON packet forwarder message for an uplink (rxpk) which will be sent Virtual LoRa packet forwarder.
In LoRaWAN, you will need real gateways and real devices for your real test case. However, it's simpler to using just simulated gateway and simulated devices in order to choose best LoRaWAN Network Server fulfills your real requirements.
lora-packet is a nice module to generate LoRaWAN uplink/downlink payloads, but in order to send them to a Network Server, Semtech UDP Packet Forwarder protocol is required.
- Node.js v8.x
``sh`
npm install --save packet-forwarder-json-builder
Compose messages to remote Network Server using Packet Forwarder protocol.
Supported messages:
- Uplink
- Join-request
`javascript
const jsonBuilder = require('packet-forwarder-json-builder')
const payload = Buffer.from('test')
const scenario = {
gateway: {},

}
}
console.log(jsonBuilder.uplink(payload, scenario))
