IoT Platform Design Doc: Double Trouble

An interpreter for a dynamically typed language needs to encode values in such a way that the value type is accessible at runtime alongside the value itself. There are a few tricks to encode the type compactly. Here, we discuss a quite common and ingenious trick, shared with some well known JS virtual machines.

IoT Platform Design Doc: Compacting GC

One of the things that make programming today so much more approachable is the the automatic memory management feature of many high-level programming languages. However, exactly this piece is often missing from embedded platforms, and there is a reason for that:  the well-established techniques used by modern Garbage Collection (GC) systems are designed with radically different trade-offs than what embedded systems with a few KB of RAM dictate.

Is there a larger IoT-potential for refrigerators?

Last week, I shared the huge amount waste each household faces simply from food that wasn’t consumed. Check out the blog post “Is there real value in smart fridges”. The solution here was simple, put a fridge in the pockets of consumers and they will buy what they need (not what they already have the fridge and forgot about). But, let’s spin the idea further. What is the larger Internet of Things potential for refrigerators?

Get Over-The-Air Updates and Security right for smart products

Smart products are here to make our lives easier. Especially smart appliances are meant to ensure that consumer can use them remotely, gain life hacks, save time and much more. It’s no wonder that many manufacturers concentrate mainly on getting the life hack aspect right. But, what happens when Over-The-Air Updates (OTA) and Security are not given the same amount of consideration?

Cookie authentication and session management [Mongoose more than an Embedded Web Server]

Cookie authentication and session management are important for web applications. Mongoose Embedded Web Server supports basic and digest authentication, which gets the job done, but, it doesn’t let web app control the UI. It’s a simple prompt created by the browser and rarely blends well with the rest of the app.

Embedded Heap Behaviour: Analysis and Improvement

The heap on a device is usually a kind of black box: heap API rarely provides anything more than just returning free space size, and quite often it doesn't provide even that (since C standard doesn't oblige it to). We have little idea of the fragmentation (in particular, we're interested in longest contiguous free chunk of memory) and the behaviour of the allocator in general. But in the resource-limited circumstances we're highly concerned about being memory efficient, right?

Web Summit - What a week for IoT

It’s post Web Summit week and once again, what a great event it has been! We reflected upon our own growth from Web Summit 2014 - arriving with our idea - to launching our Beta at Web Summit 2015 in a previous blog post. So, our expectations for Web Summit this year were high, and we are glad to say, they were exceeded. Thank you to Paddy and his team for helping to open up these opportunities for us:

IoT Connectivity - Our Experience porting Mongoose IoT Platform to TI CC3200

Part of the fun of working on Mongoose IoT Platform is that you get to play with all sorts of interesting hardware and Texas Instrument’s (TI) CC3200 is definitely an interesting one. With respectable 256K of RAM on board, full set of peripheral interfaces, integrated WiFi support, hardware crypto engines and JTAG in-circuit debugging, the only thing missing is the proverbial kitchen sink. But as we’ll come to see in this post, not all elements went as easy as we hoped.

IoT Connectivity - Flashing CC3200 for Mongoose IoT Platform

We’ve been working on the ALPHA 2 release of Mongoose IoT Platform. Key for us in this release was to ensure that we make Mongoose IoT Platform available to a broader audience. So while we first worked with ESP8266, we wanted to quickly move on to TI and the popular CC3200 chip to increase IoT connectivity options for developers.

Mongoose IoT Platform - IoT Connectivity for everything

In the beginning there was V7 and Mongoose Embedded Web Server Library. And it was good.

Based on them, we developed Mongoose IoT Platform.  

But despite the fact, that both V7 and Mongoose Embedded Web Server Library were developed in POSIX OS (OS X and Linux), the first platform for Mongoose IoT Platform was ESP8266, followed by CC3200 as two of the most popular chips out there.

Mongoose IoT Platform Alpha 2 Release

Our passion is to make embedded development so easy to use that anyone with basic knowledge of programming can do it. In order to achieve this goal, we created the world’s smallest embedded JavaScript engine, V7, and created a firmware for embedded devices that has an easy to use JavaScript interface. In July we released the first Alpha version of our IoT solution, Mongoose IoT Platform.

Cesanta’s Embedded Web Servers - New Features

Did you realise that Mongoose has been around since 2004? Since we first published the embedded web server for the first time, it’s grown - a lot. There have been several upgrades and, of course, the introduction of Meerkat (the lightweight version) and Fossa (with many additional features). Today, we announce Mongoose 6.0 and a major overhaul to the entire platform!

Smart Product Development for HVAC

Especially in the Heating, Ventilation, and Air Conditioning (HVAC) space product development into the Internet of Things (IoT) arena is becoming more and more important. Consider this, 70% of the M2M market will be dominated by two sectors: consumer electronics and intelligent buildings (including HVAC systems). Machina Research goes on to estimate the market worth by 2022 to be $18 billion. But when it comes to defining the right IoT move for your business, where should you head first?

Consumers are ready for Smart Heating Systems [HVAC Industry Changes]

HVAC_Industry_Changes_ThermostatBeing in the Heating, Ventilation, and Air Conditioning (HVAC) field these days is a good place to be. With growth predicted as high as 5.7 percent by 2018, it's a potential $120 billion industry. The global economy is on the up too, which makes for the first major growth factor. New markets are opening themselves up to air conditioning or heating systems. As a HVAC provider, you could rest and ride this wave. That is if there weren’t a second growth factor.

HVAC And Mongoose Embedded Web Server - Tutorial

HVAC_Mongoose_Embedded_Web_ServerReceiving real-time data from heating or cooling equipment is a must for many customers of HVAC businesses. A manufacturing plant may need to monitor the cooling units on its production line carefully to ensure the right temperature is always available. Real-time data here doesn’t simply allow to avoid malfunctions, it also allows to predict temperatures and ensure that no energy is wasted over time. You can achieve this transfer of real-time data from machine to control unit with an embedded web server library like Mongoose.

HVAC Industry Changes - How IoT helps you respond to consumer demands

During 2008, the number of things connected to the internet surpassed the number of people on earth (*Cisco). Hold on, that was six years ago? Phones, laptops, tablets, the first wearables, manufacturing equipment the list grew from there. And the Heating, Ventilation, and Air Conditioning (HVAC) market is not far behind anymore. But despite all these HVAC industry changes, does connectivity for HVAC products really make sense already?

Listen up Software Engineers! IoT Connectivity with JavaScript

Most of us have been there, a great idea is generated between engineers, R&D and product management. Then we, in the engineering team,  are left to make it happen. That’s the challenge and what we do the job for! But this doesn’t mean that we don’t mind finding simple solutions to complex challenges.

Failed to contact bootloader [Mongoose IoT Platform on ESP8266 Bug Fix]

Mongoose IoT Platform's flashing tool by default needs to read a couple of things from the device before flashing: 1) existing ID and 2) the flash configuration for the ESP SDK. Reading the ID is needed in order to know whether we need to generate a new one. The ID is located at offset 0x10000 and is simply a piece of JSON with SHA-1 hash: if the recorded hash doesn't match the hash of the JSON – we write a new ID.

IoT Devices - Where things stand and where we need to be

Currently, device programming is in the realm of experienced engineers who are highly skilled in the embedded space, expensive and above all hard to find. It’s not very different to personal computers. Throw your mind back a few decades; software engineers were a rare breed. The market however drove the explosion of software products across business verticals. And the industry responded by producing high-level development tools that allow a much bigger and more diverse set of engineers to create software products. Imagine things stayed as they were with Assembly and C; we’d be far from where we are today!

JSON schema and code generation

One of our goals is to build a communication platform for devices to connect to the cloud. For it to be of any use, it must be programming language agnostic and easy to use. To achieve that we decided to go with a JSON schema as a way to describe data structures and generate stubs for particular programming languages from that.

ESP8266, flash and alignment

At Cesanta, we want to bring connectivity to all devices, so, we cannot ignore a popular device like ESP8266. This device has a quite big flash, and Mongoose IoT Platform offers file operations and a flash-based file system. We use spiffs as frontend and native ESP flash functions as backend.

Open Source Software: free vs. commercial licensing

The open source movement has significantly changed the software industry over the last decade. Nowadays, open source projects are available for almost any functionality you can imagine. That gives everybody a lot of freedom; businesses as well as individuals, because there are many alternatives to choose from. So, when a business makes a decision to choose a software for its product or operation, what criteria should be considered?

Experience with Intel Galileo 2

At Cesanta, our focus is on providing connectivity to devices. This means that we often find ourselves dealing with exotic hardware. However, Intel Galileo 2 promised to be simple  due to its x86, produced by Intel, with impressively looking processor chip, decent amount of RAM and coming with a Linux distribution out of the box. Apart from testing Mongoose Premium and V7 on it, we were going to use it as a board to drive other boards in our testbed. Should be easy, right?

Why we write numbers in big endian

At some point, I was working on a deep packet inspection and database for storing network statistics. For the database, I needed a lightweight big numbers library, and I rolled out my own. The library was implemented as a single C header file with a bunch of inline functions.

CPU Stacks: Why they grow down

Any running process has several memory regions: code, read-only data, read-write data, et cetera. Some regions, such as code and read-only data, are static and do not change over time. Other regions are dynamic: they can expand and shrink. Usually there are two such regions: dynamic read-write data region, called heap, and a region called stack. Heap holds dynamic memory allocations, and stack is mostly used for keeping function frames.
