Over-the-Air ESP8266 programming using PlatformIO

There were three items on my two-do list for quite some time already: Get an ESP toolstack running on my Mac Try out PlatformIO and see if it’s nice to work with Try out video blogging (or vlogging) So, why not combined the three to-do items into one experiment? So yesterday I got my gear ready and started experimenting and recording and editing, almost all at the same time. Here’s there result: In this video I have installed an ESP toolstack using platform IO with the statements below:

Since PlatformIO version 2.7, PlatformIO doesn’t have a dependency on scons anymore, hence…

Arduino programming on the ESP8266

The ESP8266 has been gaining quite some popularity in the Internet of Things space. It is affordable and tiny and has multiple programming options. You can use Lua or C code to program the chip and it can virtually do anything you can also do with an Arduino. Some folks in the ESP8266 community have been debating about how great it would be if there were a third programming options. The ESP8266 should be made compatible with Arduino code! Richard Sloan and Ivan Grokhotkov eventually stepped to the plate and did the work to add the ESP8266 as a board to the Arduino…

Why you should use MQTT in IoT projects and why SAP should support it

While designing an IoT device, there are multiple options to connect them. Once of the considerations should be the protocol being used to chat to other devices or to a server. Previously, I would have easily chosen to make the interface REST based and have done so with Jeenode project a few years ago. But REST is not ideal as it is designed around a simple request/response model. So you ask “did my account balance change” and the response is returned “no it did not”. So you check again a few minutes later, and get the same response. Sound like…

Getting started with the ESP8266

I’ve always loved to play with Arduino’s, but also thought it was underequiped. There must be at least something that connects it to a network and should have at least a radio on board. Because of that I got really excited about Jeenodes, which had a RF12B radio on board (really good for low-energy, battery operated stuff), and was a couple of factors smaller than an Arduino at the same time. But that was back-then. Theres a new kid on the block that offers a very nice set of features, and doesn’t only just have a blip-radio built-in, but has…
