Help with reading data from csv in BangleJs2

var getData = require('Storage').read('rawData.csv\1');

This only reads chunk 1 of the Storage file, see here for an explanation about those.

You probably want something like this:

var dataFile = require('Storage').readopen('rawData.csv', 'r');
var line = dataFile.readLine();
while (line != undefined) {
        Bluetooth.println(`<data>\n${line}\n</data>`);
        line = dataFile.readLine();
}
dataFile.erase();

Also:

var memory = require("Storage").getStats();

Shouldn't this be var memory = require("Storage").getFree(); ?
