It turns out that the reason I couldn’t get the Olimex esp8266 to work properly was that my USB/serial converter was faulty. The replacement one arrived today, and now I can program the wifi module using the arduino IDE with no problem. Five seconds after programming it, it had connected to my home network and was sending temperature readings via MQTT to my raspberry pi server. https://robinsonia.com/posts/2014-09-23-more-tiny-wifi-success/ Tue, 23 Sep 2014 00:00:00 +0000 https://robinsonia.com/posts/2014-09-23-more-tiny-wifi-success/ As I have posted before, I have been playing with the super-cheap WI07C WiFi module based on the ESP8266 chip. I’ve now had sufficient success with it that I can publish a post on a working project. This simple setup uses an Arduino nano to read temperatures from to 18BS20 sensors, formats the data as JSON and then sends it over WiFi to a server on my home network. It’s cheap and simple. https://robinsonia.com/posts/2014-09-11-wifi-success-for-a-change/ Thu, 11 Sep 2014 00:00:00 +0000 https://robinsonia.com/posts/2014-09-11-wifi-success-for-a-change/ I’m actually having success in connecting the super-cheap WI07C wifi module to my home network, so that an arduino can send data anywhere. [caption id=“attachment_373” align=“alignnone” width=“300”] WI07C module featuring esp8266 chipset[/caption] I can now reliably establish a TCP connection and send data back and forth. It works rather well, with some limitations. It helps that I came across some slightly better documentation, sourced from this esp8266.com forum post which lists a few more AT commands and some more illuminating explanations. https://robinsonia.com/posts/2014-09-09-wifi-for-less-than-a-fiver/ Tue, 09 Sep 2014 00:00:00 +0000 https://robinsonia.com/posts/2014-09-09-wifi-for-less-than-a-fiver/ Last week, the excellent hackaday ran a story about a new WiFi module (the Wi07c) based on the ESP8266 chip. It is eminently suitable for attaching to an arduino or similar, but it only costs $5. As I’ve been whining for some time about the high cost of WiFi shields for arduino, this piqued my interest. I bought a couple from the electrodragon store and have now had a bit of time to play with them.
