Re: Official MicroPython MQTT client

i copied the file 'simple.py' which looks like the module file into micropython/esp8266/scripts and rename it as 'mqtt.py' and then i made the new port file ,wrote it into my 8266.

and then i can import mqtt it looks work!

1. you may need the resistance to make the voltage no more than one V;
2.0-1 V map to 0-1023 in ADC
