WiFi connectivity – Spark Core vs Particle

April 4, 2016 IoT, Particle , , ,

Over the last few days I have been struggling to get my Spark and Particle Photon connected to my home WiFi seamlessly.

The Particle board connects to WiFi instantly. When I tried connecting my Spark Core, it fails continuously. Spark Core would always blink GREEN and would never get connected to my home WiFi.

I tried flashing the lastest software using dfu-util

particle flash --usb cc3000_1_14

It did not connect. I tried connecting using Mobile Hotspot (using LG G4 Android), Home WiFi and Xiaomi USB Access Point. Particle Photon Board was able to connect to all of them successfully; Spark Core could only connect to Mobile Hotspot. This meant that there were some settings in the other two WiFi that were creating issue.

Finally, the electronics engineer in me took up the challenge and I started reading the datasheet of both boards. Below are the findings and the way to fix this

Particle Photon Board

  • Uses Broadcom BCM43362 chipset that works with IEEE 802.11 b/g/n device classes at 2.4GHz (single band)
  • Connects well with Channels 1-13 (tried by myself)

Spark Core Board

  • Uses CC3000 chipset that works with IEEE 802.11 b/g device classes at 2.4 GHz (single band)
  • Connects well with Channels 1-11

The Fix

With this knowledge, I tried to analyze my home WiFi connecting using 3 different WiFi connections

  • Home WiFi (AzTech repeater) using mixed mode 802.11 b/g/n at 2.4GHz was using Channel 12. I changed the channel to Channel 5 and rebooted the router but it still used Channel 12. This was because the repeater was connected to DLINK router (main router) that was broadcasting on Channel 12.I manually configured to use mixed mode 802.11 b/g/n with Channel 10. A restart of modem and Spark Core could finally connect to main router. A restart of repeater was required to have Spark Core connect successfully to the repeater network.

Spark Core


  • Xiaomi USB Access Point: I could not manage to connect using this even with Channel 1. I believe this uses 802.11 n mode.

WiFi Analysis

For this analysis, I used WiFi Analyzer on Windows Store. This application displayed all key information required to troubleshoot this.

After fixing the router, WiFi analyzer output looks like,



So in a nutshell,

Spark Core needs 2.4Ghz 802.11b/g CH 1-11 whereas Photon works with 2.4GHz 802.11b/g/n CH1-13

PS: I had posted the problem on Community forum and troubleshooted this problem. Detail steps also available at:

Session – Internet of Things – Devices and Azure Telemetry (Azure Florida Association)

March 24, 2016 Azure, IoT, Sessions , ,

I am really excited to share my upcoming session on Internet of Things – Devices and Azure Telemetry organized by Azure Florida Association.

The session will be online on GotoWebinar and in one hour I will cover range of topics on Internet of Things.

Date: 30 March 2016 9:00 PM SST (UTC+8)
Duration: 1 hour

What’s on the plate?

The topic of “Internet of Things” pops up in almost every geek world and yet it’s the term that has been misinterpreted the most. This session will cover what’s Internet of Things and the various IoT devices in the market, their inter-communication and how these devices can send telemetry to the Azure world to generate real time analytics and business insights

Register yourself for this free session at Register : Internet of Things – Devices and Azure Telemetry

Raspberry PI to Detect Network Bandwidth (using NodeJS)

March 21, 2016 IoT, NodeJS, Raspberry PI , ,

Couple of weeks ago I did an experiment on my Raspberry PI 2 to detect the speed of my ISP using a lot of Shell scripts. The end result was quite satisfying as I could post a tweet like the one below to let my ISP know that the Internet speed at my home wasn’t good enough. I had few follow-ups with my ISP’s support team and now the Internet speed is quite good

I thought over it to automate this and I had two options – cron jobs or move this to more managed code like NodeJS. I tried multiple libraries and finally nailed on npm library speedtest-net.

var speedTest = require('speedtest-net');
var test = speedTest({ maxTime: 5000 });
test.on('testserver', function (server) {
        pingTime = server.bestPing;

test.on('data', function (data) {
         var downloadSpeed = + ' Mbps';
         var uploadSpeed = data.speeds.upload + ' mbps';

         console.log("Download speed", downloadSpeed);
         console.log("Upload speed", uploadSpeed);

test.on('error', function (error) {

The next step was to send a tweet to Twitter. I had two options to this – use Twitter API or adopt IFTTT platform. I preferred IFTTT as it gives me options to trigger an event and associate any action for the event. So I could, today choose, to tweet the speed and could tomorrow also have it emailed or routed to another channel.

I created an API key on IFTTT Maker Channel and created a Recipe with Trigger Channel as Maker. Event Name (as shown in below screenshot) defines the event that your code will invoke








As part of “THAT” action, I selected my Twitter Channel to Tweet the event data. Maker Channel allows us to send 3 values “Value1”, “Value2” and “Value3”

With this, I was ready to wire code to send my Network Speed to Twitter. I changed my NodeJS code to use NPM library node-ifttt-maker as below,

var IFTTT = require('node-ifttt-maker'),
         ifttt = new IFTTT('my-ifttt-maker-api-key');
var minDownloadSpeed = 50; // 50% of promised speed 100 Mbps?

// Send Alert only when speed is less than min download speed
        if ( < minDownloadSpeed){     
                event: 'speedtest',
                method: 'POST',
                params: {
                    'value1': data.server.location,
                    'value2': downloadSpeed,
                    'value3': uploadSpeed
            }, function (err) {
                if (err) {
                } else {

When the speed test completes (i.e. “data” function) it sends a POST request to IFTTT Maker Channel with relevant information and the Maker Channel routes it to the preferred channel (in this case Twitter). With no code change, you can change the output to Email, Facebook, GitHub, Google Drive, OneDrive, etc.

Now you can run this NodeJS code to monitor your network.

With this, running at regular intervals (not too often though) you can monitor your network speed and decide when to stream Netflix. That’s how I get a seamless streaming experience.

Caution: Ethernet Ports have a bandwidth defined. Raspberry Pi (as of 20 March 2016) does not support Gigabit Ethernet so before tweeting in public check the max bandwidth your IoT device supports and do not try this over WiFi as WiFi speeds may be slower.
