    Secure Remote Debugging for IoT Connected Devices Secure Remote Debugging

    One of the challenges confronted by embedded device developers is what happens when something goes wrong with an IoT device – meaning you can no longer connect to it. Bad news if this happens to a single device in the field, but commercially disastrous if the same issue affects even a small proportion of your fleet of IoT devices.

    Imagine that a software bug escapes your otherwise comprehensive device test plan resulting in an interruption to the connectivity of 10% of your deployed devices; even in this case the cost of recovery would be huge.

    Issues like this do unfortunately happen, and while you know that software bugs occur, and no doubt can be fixed, the risk-impact of issues like this is significant.

    Separating the connectivity stack from the application code guarantees device reachability

    Obviously, being able to guarantee connectivity to your remote edge devices is important – Twilio Microvisor …

    VPN connectivity for your IoT devices VPN - Social Banner

    I am excited to announce that Super SIM now has VPN (Virtual Private Network) support, enabling you to set up secure private networks between Twilio and your application data centers and have your Super SIM connected devices use these private networks. With regular Internet breakout, the traffic from devices using Super SIM will go over the Internet and get routed to your application data center. When VPN is used, the same traffic is sent over a secure and private tunnel as shown below:

    The benefits of using VPN for IoT devices

    With a VPN that tunnels your device connectivity, you get the following benefits:

    • Secure channel - A secure data channel is created between Twilio and your data center. All traffic to/from the devices going through this data channel is encrypted and does not go over the public Internet unprotected.
    • Private end-to-end network …

    Build an IoT Doggy Alarm so Your Furry Friend Can Tell You They Want To Go Outside IoT Doggy Alarm Header

    Sometimes dogs like to mistake furniture for a toilet. Out of fear for my new shoe cupboards, I decided to make a doorbell for my dog, Bobby, to push to alert me when he needed to go outside. It took a little while (and cost me a lot of treat-based incentives) to get him to push it, but soon enough, Bobby would stand by the door... and wait until I could see him to push the button. This got me wondering: could I build something where I would be notified when he stands close to the door?

    In this guide, I will show you how to build a sensor capable of detecting your fluffy friend’s proximity to your door then send you a text message alert, using an Arduino and Twilio’s Programmable SMS.

    It’s that time of day. Your dog wants to go outside and stands by the …

    Overcoming IoT security threats from the start IoT Security

    Here’s the sobering reality: across the Internet of Things (IoT), security has been overlooked. An amazing 1.51 billion IoT devices were breached in the first six months of 2021, an increase from 639 million in the same time period in 2020. With the anticipated number of connected devices worldwide predicted to reach ~29 billion by 2030, there is still a lot that needs to be done to ensure that these devices are protected from attacks.

    IoT security is hard to predict

    Consumers and device builders are increasingly aware of the importance of device security, but it can be challenging to know which devices are secure by design and which just haven’t been targeted yet. And for many device builders, security is an afterthought as they prioritize the features of the product or service itself when working towards a minimum viable product. Equally, security can sometimes be …

    What is an IoT Device? What is an IoT Device

    The IoT, or Internet of Things, is one of the most promising areas of technology to help solve today’s real world problems of the physical world, be it related to our changing climate, public health, public safety, transportation, or even our convenience with living in a modern home. If you are new to IoT, you can read up our definition of What is IoT. Use cases are found in every major industry, from healthcare to agriculture to retail to government. We have put together a list of the top IoT use cases across industries for your perusal as well.

    In this article, we want to dive deeper into the devices, the “things”, that make up the Internet of Things.

    Shutting Down Rogue IoT SIMs Fast Shutting down Rogue SIMs Fast

    This is Part 2 of our series on Efficient SIM Management. Missed Part 1? Read up on it here: IoT Fleet Management: Simplify SIM Updates

    In the world of large-scale IoT deployments, it is critical to be able to quickly identify and shut down a single device that may have been compromised.

    Let’s imagine that you are a fleet operator working for an environmental research company. Your business manufactures hundreds of sensors and deploys these around the Mississippi River. Collectively, these sensors monitor the river level, informing a team of researchers whether the level is high or low. Every hour, your sensors wake up, record how high the river is, send this data to your cloud, and then go back to sleep to conserve battery power.

    One unfortunate day, a thief steals a SIM card located in one of your sensors. They have plugged this SIM card into their iPad …

    Twilio and Sony Partner to Enable Voice Calling on Low-Power, LTE-M Cellular IoT Devices Embedded Voice over LTE-M

    Voice is still the preferred choice for people who want to communicate, and millions of developers already know how Twilio gives them the power to add voice communications to their products with just a few lines of code. These products, such as wearables, IoT, and smart devices are getting smaller and smaller and becoming more a part of our lives every day. Now with Sony Semiconductor and Twilio, you can quickly and easily add voice communications to your small-footprint, low-power, and low bandwidth IoT device. All you need is an ALT1250 chipset within your device, a SIP or WebRTC client and a microphone and speaker. This new capability means simplified design and reduced cost for portable, low-power IoT devices with global voice functionality.

    Meet us in person at Embedded World in Nürnberg, Germany, June 21-23 2022 for a live demo! Find us at the Sony Semicon booth in Hall …

    What is IoT? Examples and Use Cases of the Internet of Things Across Industries What is IoT? Examples and use cases of the Internet of Things across industries

    What is the IoT?

    The Internet of Things, or IoT for short, is the concept of connecting physical objects to the Internet so that they can be either controlled or monitored remotely, with the goal of gaining insights that help improve personal or business outcomes. Physical objects can either be connected directly, or via sensors that are attached to the object. Objects can be anything from everyday personal things such as doorbells, thermostats, lights, or watches, to industrial or commercial devices such as solar panels, medical equipment, point-of-sale terminals, factory robots, parking meters, vehicles, all the way to the environment itself: rivers, forests, public spaces, etc.

    There is a wide variety of examples for how IoT can add value to businesses and the world. The following paragraphs provide a mostly comprehensive overview of IoT use cases, with short descriptions and value propositions for each.
