Combining OSTree and SW Containers for reliable IoT Device updates

CNXSoft: This is a guest post by Drew Moseley, Technical Solutions Architect at Toradex, explaining how the company updates Linux IoT devices firmware with OSTree (aka libostree) open-source operating system build and deployment tool, as well as Docker software containers. Every day more and more connected devices are being brought to market and estimates for the total size of the Internet of Things (IoT) market are as high as $1.5 trillion by 2027. Gas pumps, medical devices, and point of sale systems are increasingly connected, making it virtually impossible to avoid interacting with these devices, even for complete Luddites. In the home, devices such as power meters, light switches, and security cameras are commonly internet-enabled allowing for smart home functionality. The level of complexity in the software for these devices increases with the functionality, and the number of devices with software defects in the field is growing. In many cases, […]

ESP32-WROOM-DA dual PCB antenna WiFi module aims for longer range, better reliability

Espressif Systems ESP32-WROOM-DA is another ESP32 based WiFI & BLE module with a twist as its dual PCB antenna design aims to provides a longer range and more reliable connectivity by automatically switching to a specific PCB antenna depending on signal strength. The new module features ESP32-D0WD-V3 dual-core Xtensa LX6 dual-core processor with a maximum frequency of 240 MHz, along with 520 KB of SRAM and 448 KB of ROM, and has been designed to be pin-to-pin compatible with ESP32-WROOM-32E module found in products such as Pico Wireless, in order to ease migration between the two modules. Espressif did not provide detailed specifications for the new WiFi module, but assuming it’s mostly based on ESP32-WROOM-32E design, ESP32-WROOM-DA should have the following key features & specifications: WiSoC – Espressif Systems ESP32-D0WD-V3 embedded, Xtensa dual-core 32-bit LX6 microprocessor, up to 240 MHz with 448 KB ROM for booting and core functions, 520 […]

Sonoff & Tuya smart plugs found to transmit unencrypted passwords

There are many low-cost smart plugs based on ESP8266 that provide a convenient way to control lights or home appliances with your smartphone. But cybersecurity firm A&O IT Group found vulnerabilities in ITEAD’s Sonoff S26 and Ener-J Wi-fi (Tuya) smart plugs that would allow an attacker to easily access your wireless network. The first security vulnerability is pretty common and hard to exploit since it’s only a concern during the setup. Sonoff S26 starts itself into access point mode with ITEAD-1001xxxxxx SSID, and is set up through the eWelink app with the user not needing to know the password. But with older firmware is was needed, so ITEAD still shares the default password: 12345678 in the user manual, and it can be used to connect to the smart plug by anyone. But once configured, it’s not accessible anymore as the smart plug should be in client mode connected to your […]

Why you should request open-source software for your IoT devices

PineTime open-source software Gadgetbridge

I usually think of open-source hardware and/or software are enabling skilled people to more easily fix bugs, improve on the design, get feedback from the community, etc… But in a world where IoT devices become more prevalent, there’s another reason why you should request open-source software: Long term support. What made me think about are two things. The first one if that I own WeLoop Hey 3S smartwatch, which I love and wear since March 2018. That’s quite a feat since most cheap devices I own often only last a few months or a year or so. I’m also used to the watch face and Weloop app interface. So what’s the problem exactly? WeLoop company closed on December 31, 2019, and while the app worked fine for about a year after that, recently I have been unable to login to the app to access my data and/or update settings for […]
