Is it resilient?

Have you tested the resilience of MQTT under conditions of poor WiFi communications? I found getting reliable operation quite difficult. To add to this you can never prove you've succeeded as there are so many ways a wireless link can be disrupted. Some interesting tests are: Run it for long periods...

Re: MemoryError: memory allocation failed, allocating %u bytes

To use frozen bytecode you need to be able to build the firmware. Instructions are here . Once you can successfully build and flash a firmware build, freezing bytecode is done by putting your Python source in ports/esp8266/modules/, building and flashing. Issuing >>> help('modules') will list module...

Re: NodeMCU and WiFi disconnects

@crayfish The limitations are inherent in radio technology: WiFi connectivity suffers outages for a number of reasons. Any code using WiFi needs to make provision for this and ensure that the link is re-established after an outage. PC operating systems can do this transparently and give an illusion ...

Re: MicroPython Sprint at SciPy 2018

Sounds great. It would be good to see scientific data analysis libraries ported to MicroPython.

With all due respect to a certain Mr Orwell, I couldn't help noticing your "Scientific MicroPython on Microcontrollers" tutorial is to be held in Room 101 ;)
