Routers are usually pretty stable devices, but sometimes they still hang, and I think I must reboot my router about 2 to 3 times a year as I lose (Ethernet) connectivity. I’m usually at home, so it’s not really an issue as I can just walk a few meters to manually reboot the router. But if you are often on the go, and have a few WiFi devices such as smoker alarms, smart lights, and other home automation products that you may want to control over the Internet, if WiFi goes down nothing works. Luckily there’s a solution: WiReboot, a small device powered by ESP8266 that will check your WiFi and Internet connection, and automatically restart the router if it fails.Key features of WiReboot: ESP8266 module for 802.11 b/g/n WiFi connection USB – 1x USB input port to connect your router power supply, and 1x USB output to connect to […]

Espressif ESP8285 is just like ESP8266 but with 1MB built-in Flash, and Designed for Wearables
Espressif announced ESP8285 WiFi SoC was entering production last March. The new processor is based on ESP8266, but the company added 1MB built-in flash to make the solution smaller, and more suitable to wearables such as smartwatches and activity trackers. ESP8285 features a Tensilica L106 32-bit MCU and another ultra-low-power 16-bit RISC core, as well as 802.11 b/g/n/d/e/i/k/r WiFi connectivity. AI Thinker has already produced a tiny module based on the solution, called ESP-8285, and another person has developed an ESP8285 development board sold on Tindie for $24.95, and with some code sample (Arduino sketches) on Github. You’ll also find some more technical information on a Devacron blog post, or inside the datasheet on Espressif website. Via Hackaday Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later […]
STAR OTTO Arduino Board is Based on STMicro STM32 32-bit Cortex-M4 MCU & ESP8266 WiFi SoC

Programming ESP8266 Boards with a Smartphone
In recent days, I wrote about low cost MCU boards such as the $2 BluePill, and the One Dollar Board project, but several people commented that while the board themselves are very cheap, it might still be a problem in some developing countries, where access to computers cannot be taken for granted. So person suggested that such initiative would work better in some countries if programming was possible via a smartphone instead. Is that true? According to a 2014/2015 study by Pew Research Center, there is some truth to it, but it varies greatly between countries. For example, 55% of Brazilian adults own a computer at home, while only 24% own a smartphone, but in Kenya only 8% own a computer at home, while 15% own a smartphone. Some devices in the “cellphones but not smartphones” might be feature phones with WiFi and a web browser. Anyway ideally a low […]
Getting Started with Wio Link Starter Kit, Visual Programming Android App, and IFTTT
Wio Link is a board based on ESP8266 WiSoC that is supposed to be easy to set up thanks to Grove modules – no breadboard and mesh or wires – and, as I first understood it, to program thanks to a drag-and-drop mobile app that does not require any actual programming. More advanced users can also use a RESTful API in Python, JavaScript, Node.js, PHP, Objective-C or Java. I’ve been sent a $49 Wio Link Starter Kit including the board, a USB cable, and six Grove modules to evaluate the kit. I’ll start by having a look a the kit, before experimenting with the Wio Link Android app. Wio Link Starter Kit Unboxing The kit is sent in a red plastic case. Wio Link board is lodged in the top cover, and other accessories are placed in bags in the main part of the case. Let’s check the board first. […]
