SenseCAP T1000 Tracker Decoder for Ubidots

JavaScript
After creating the plugin in Ubidots, go to the Decoder section, delete all the code and replace it with the following code.
const HOTSPOT_INFO = false;

function handleErrorIfExists(data){
    const error = 'error' in data;
    if (error) {
        const errorMsg = { "error": { "value": data.errorCode, "context" : { "reason": data.error } } };
        return errorMsg;
    }
    return false;
}

function addLat(lat, ubidotsPayload){
    ubidotsPayload.position.context.lat = lat;
}

function addLng(lng, ubidotsPayload){
    ubidotsPayload.position.context.lng = lng;
}

const coordinateActions = {
    "Longitude": addLng,
    "Latitude": addLat,
}

const assignPayloadKeys = (data, ubidotsPayload) => {
    const { type, measurementValue } = data;

    if (type === "Longitude" || type === "Latitude") {
        if (!ubidotsPayload.position) {
            ubidotsPayload.position = { "value": 1, "context": { "lat": undefined, "lng": undefined } };
        }
        coordinateActions[type](measurementValue, ubidotsPayload);
    }
    else if (data.type === "Timestamp") {
        ubidotsPayload.timestamp = data.measurementValue;
    }
    else {
        ubidotsPayload[type] = measurementValue;
    }
};

function buildUbidotsPayload(data){
    const ubidotsPayload = {};
    data.forEach(innerData => {
        innerData.forEach(innerInnerData => {
            assignPayloadKeys(innerInnerData, ubidotsPayload);
        });
    });
    return ubidotsPayload;
}

async function formatPayload(args){

    const data = args.uplink_message.decoded_payload.messages;
    let ubidotsPayload = {};

    const error = handleErrorIfExists(data[0][0]);
    if (error) return error;

    if (HOTSPOT_INFO) {
        const { hotspots, port, fcnt } = args;
        const { snr, rssi } = hotspots[0];
        Object.assign(ubidotsPayload, { SNR: snr, RSSI: rssi, port, 'Frame Counter': fcnt });
    }
    ubidotsPayload = buildUbidotsPayload(data);
    console.log(ubidotsPayload);
    return ubidotsPayload;
};

module.exports = { formatPayload };
