ESP8266 Network Configuration

One of the more challenging issues with wireless sensor nodes is performing the initial configuration required to get them to connect to your wireless network in the first place (in this case I am talking about 802.11 a/b/g/n based WiFi networks). To connect to a WiFi network a sensor needs to have at least two pieces of information - the SSID (network name) and a password to grant access to that network - the problem is how to provide that information to a brand new, just programmed sensor? The quickest and easiest solution is to include it in the source code for the firmware and have it alwa…

NotDuinos - The Arduino Core on Other Devices

In my last post I mentioned that there was an Arduino compatible core available for the ESP8266 - in this post I cover how to install this core as well as cores for other non-Arduino hardware. A Brief History of Arduino The Arduino system started in 2005 as a project platform for students and consists of a hardware platform (based on the Atmel ATmega chips) as well as a software library (based on Wiring). Wiring was originally designed for use by artists and designers so the focus was on ease of use and good documentation - although it uses C++ as the implementation language many of the langua…

ESP8266 - The Easiest Way to Automate Your Home

Recently I've been looking at a way to quickly build and deploy some wireless sensors to feed data into my home automation system and took a second look at the ESP8266 modules sitting in my parts drawer - these devices seem to be the quickest, cheapest and easiest way to get a remote sensor network up and running. I have had some ESP-01 modules for a while now but haven't had a lot of opportunity to play with them (I've been working on other projects) and it seems that there have been a lot of improvements in the ecosystem since I last looked - a wider range of modules and development environm…
