Yesterday I tried to switch protocol of backend -> browser UI update channel of my solution to mqtt and it works quite well, better than socket.io I used paho-mqtt for python backend (over TCP) and mqttws31.js (over WebSocket) for browser side running on test.mosquitto.org.

kfricke , I think that a lot of people from MicroPython community would really be grateful for efficient and resource-saving implementation of MQTT client for MicroPython. From my point of view, emulation of HTTP requests si the only way how to talk to the Internet taking into consideration current...

You are right, even local supplier in Slovakia has it in his e-shop. I hope that fatfs will be supported in the near future.

I would like to ask, is someone already working on fatfs support?

ESP8266-12E seems to have those pins broken out: http://www.esp8266.com/viewtopic.php?f=13&t=3023 http://www.aliexpress.com/store/product/1-pcs-x-ESP-12E-ESP8266-Enhance-version-of-ESP-12-WiFi-Serial-Transceiver-Module-REMOTE/1795334_32336161197.html I guess it should be possible to connect SD-card ...

Looking at this table http://www.esp8266.com/wiki/lib/exe/detail.php?id=esp8266_gpio_pin_allocations&media=pin_functions.png (from this page http://www.esp8266.com/wiki/doku.php?id=esp8266_gpio_pin_allocations) I was thinking to use GPIOs 6-11 for connection to SD card and GPIOs 12-15 for connection...

Few question related to MicroPython running on ESP8266:
- is it possible to boot from SD-card in SDIO mode and "mount" it to the file system?
- is it possible to use SPI interface?

I took a quick look at current implementation of paho-mqtt for Python. It has following dependencies: errno - several error codes used in the code (following module could be extended with necessary error codes and imported https://github.com/micropython/micropython-lib/blob/master/errno/errno.py) pl...

Are there any news regarding possibility of MicroPython running on this MCU?

Thank you for explanation, it is clear now. For the initial prototype I will use pyboard + CC3K. Hopefully later something like CC3200 or ESP8266 but with 2x integrated 12-bit DACs becomes available and supported by MicroPython, including sockets. EMW3165 is rumored to have DAC integrated, however t...
