I have set up 10 Flic Hubs to run a code that sends a ping to my API. The code runs in an infinite loop with 1 hour sleep so I've had a ping every hour from every device.

All seemed perfect until all of the devices stopped working around the same time.

I've got below error on the SDK:

SyntaxError: unterminated statement (line 2)
    at [anon] (root/heartbeat/main.js:2) internal
    at [anon] (duktape.c:71822) internal
    at loadAndCompileUserModule () native strict preventsyield
    at require (init.js:122)

    at runInit () native strict preventsyield
    at handlePacket (pipe_communication.js:48)
    at readCallback (pipe_communication.js:93) preventsyield

Line to corresponds to either of below lines:

var buttonManager = require("buttons");
var buttons = buttonManager.getButtons();

Here is how my code looks like:

// Heartbeat.js
var buttonManager = require("buttons");
var buttons = buttonManager.getButtons();
var http = require("http");

var url = "my_api_url";
var DEVICE_ID = 'hub_id'

function myLoop() {
    setTimeout(function() {
        for (var i = 0; i < buttons.length; i++) {
            var button = buttons[i];
            http.makeRequest({
                url: url,
                method: "POST",
                headers: {
                    "Content-Type": "application/json"
                },
                content: JSON.stringify({
                    'pressedAt': Date.now(),
                    'batteryStatus': button.batteryStatus,
                    'button_sn': button.serialNumber,
                    'activeDisconnect': button.activeDisconnect,
                    'connected': button.connected,
                    'batteryStatus': button.batteryStatus,
                    'uuid': button.uuid,
                    'flicVersion': button.flicVersion,
                    'firmwareVersion': button.firmwareVersion,
                    'key': button.key,
                    'passiveMode': button.passiveMode,
                    'device_sn': DEVICE_ID,
                    'dataType': 'heartbeat'
                }),
            }, function(err, res) {
                console.log("request status: " + JSON.stringify(res));
            });
        }

        myLoop();
    }, 1000 * 60 * 60)
}

myLoop();
console.log("Started");

Anyone have any ideas?
Thanks.

I've had a similar problem today. I connected my Flic Hub to the Ethernet port while being connected to wifi. Then I disconnected wifi from the mobile app.

I clicked on Test Connection and confirmed the Internet access however Ethernet was showing not connected in the app however I couldn't log in to the SDK.

While the Flic Hub was powered, I removed the ethernet cable and plugged back in and it reassigned the IP. Then it worked.
