I am the happy recipient of a PyBoardv1.1. I wish to use mqtt. I found the umqtt.simple package. I apologize for a perhaps dumb questions - but I couldn't find install instructions. How do I install this library https://pypi.python.org/pypi/micropytho ... simple/1.3 as a library accessible via >>>from umqtt.simple import MQTTClient

Thank you.

If you install the latest release build of firmware (esp8266-20170108-v1.8.7.bin) from http://micropython.org/download you should find it ready installed.

There is a FAQ on MQTT here http://forum.micropython.org/viewtopic. ... FAQ#p12683.

Thank you VERY much for your reply. I installed 1.8.7 for the PyBoard 1.1...here is REPL output:

MicroPython v1.8.7 on 2017-01-08; PYBv1.1 with STM32F405RG

SADLY - when I enter:
>>> from umqtt.simple import MQTTClient
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: no module named 'umqtt'

MicroPython 1.8.7 doesn't seem to include umqtt.simple

You note umqtt Is included in MicroPython 1.8.7? What am I missing...

How do I tell what libraries are part of the MicroPython build (within REPL)?

Thank you.

help('modules') on very recent builds will show the available options.

mqtt isn't included by default with the pyboard since the pyboard doesn't have any network access by default.

Thank you. The help('modules') is very useful!

OH SNAP - so here I am tightly correlating MicroPython with networking....silly me...drat. The PyBoard V1.1 does not have a network chip (like the ESP8266)...shoot...I really like the PyBoard's implementation of UART, but useless to me if I can't use mqtt. Is there an ESP8266 board you would recommend? But then, all are limited to the machine's module which just has UART0 for RX/TX ....and I was having problems receiving data (whereas the UART receive w/ pyb worked very well).

The officially supported ESP8266 board is the Adafruit Feather Huzzah https://www.adafruit.com/products/2821.
