Convert the LwM2M JSON encoding written by AVSystem's Coiote Azure integration to nRF Asset Tracker's LwM2M JSON encoding.
AssetTrackerv2 firmware to LwM2M Asset Tracker v2 through Coiote-Azure objects version mapping
| Name | AssetTrackerv2 Firmware | Coiote-Azure | LwM2M Asset Tracker v2 | | ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------- | ---------------------- | | Device | 3:[email protected] | 3:[email protected] | 3:[email protected] | | Connectivity Monitoring | 4:[email protected] | 4:[email protected] | 4:[email protected] | | Location | 6 | 6 | 6 | | Temperature | 3303:1.1 | 3303 | 3303:1.1 | | Humidity | 3304:1.1 | 3304 | 3304:1.1 | | Pressure | 3323:1.1 | 3323 | 3323:1.1 | | Config | 50009 | 50009 | 50009 |
Where ":" indicates the object version and "@" indicates the LwM2M
version. if not present, values will be the default option. Default LwM2M
version is 1.0. Default object version is 1.0.
Installation
npm install --save-exactRunning the tests
After cloning the repository:
npm ci
npm testExample usage
import { converter } from './converter.js'
const deviceTwin = {} // ... full device twin
const result = await converter(deviceTwin)
console.log(result)See ./src/example.ts for more details.
Expected input
Result of the integration between Coiote and Azure.
