Namespace uplink

Process messages received from devices.

Example

import * as message from 'jooby-codec/analog/message/uplink';

// binary data received from a device
const bytes = [0x0c, 0x01, 0x00, 0x58];

// decode it
const payload = message.fromBytes(bytes);

if ( 'error' in payload ) {
    console.log('decode failure:', payload.error, payload.message);
} else {
    console.log('message decoded:', payload.commands);
    // output:
    [
        {
            id: 12,
            name: "correctTime2000",
            headerSize: 2,
            bytes: [ 12, 1, 0 ],
            parameters: { status: 0 }
        }
    ]
}

Example: with config

import * as message from 'jooby-codec/analog/message/uplink';
import * as hardwareTypes from 'jooby-codec/analog/constants/hardwareTypes.js';

// binary data received from a device
const bytes = [0x62, 0x20, 0x09, 0x1e];

const config = {
    hardwareType: hardwareTypes.GASI3
};

// decode it
const payload = message.fromBytes(bytes, config);

if ( 'error' in payload ) {
    console.log('decode failure:', payload.error, payload.message);
} else {
    console.log('message decoded:', payload.commands[0]);
    // output:
    [
        {
            id: 96,
            name: 'lastEvent',
            headerSize: 1,
            bytes: [98, 32, 9],
            config: {hardwareType: 3},
            parameters: {
                sequenceNumber: 32,
                status: {
                    isBatteryLow: true,
                    isMagneticInfluence: false,
                    isButtonReleased: false,
                    isConnectionLost: true
                }
            }
        }
    ]
}
