=Memory Usage=&lt;br /&gt;
&lt;br /&gt;
Talking to the ESP8266, dealing with its quirks, and putting a MQTT client on top easily consumes half of the 32kB of program memory and half of the 2kB data memory normal Arduinos have to offer.&lt;br /&gt;
&lt;br /&gt;
I first tried to let the air out of the PubSubClient and ESP8266Client libraries, succeeded to a degree, and then decided to write my own MQTT- and ESP8266 libs, designed to rely on streaming as much as possible and to reduce the use of buffers to a few and small occasions, and make use of more compact and readable code.&lt;br /&gt;
