Yes, we had two versions already. Maybe check your spam box.

Don't forget to erase the flash completely. Sometimes, when the configuration area of the flash gets into a certain state, those boards get into a restart loop.

The firmware is great and so far runs very well. I had it crash on me when I used os.listdir() right after creating the filesystem (by importing boot_), but I suppose that this is the result of some buffering. I'm especially happy about the I2C functionality, even though it's write only so far, beca...

There isn't really anything special. A simple pure-python module that doesn't interact with the hardware should work just like that. There may be room for some improvement in making it use less memory and so on, but generally Micropython is just Python. Things that touch the hardware need to be writ...

No, I have personally not tested it, I know about the limitations from lurking on the #esp8266 channel on freenode.

No, at the moment you have to compile it. As soon as there is support for a filesystem, you should be able to upload it instead.

And now that you told about it, what happend if I have 30 ESP8266 sensors, and around 10 wake up and try to connect simultaneously to ESP82266 AP? I think that last 5 to connecte will to try and down. So in my app I need to try again (loop) until send the data, right? Well, usually you make them re...

You can connect multiple ones, but surely not 50 of them. With nodemcu the limit was about 4-5, but I'm not sure if that's something in hardware or software. Then again, why would you keep them all connected at the same time? If they are sensors, it's better to make them sleep most of the time, and ...

This is funny, because it shows "rst cause:2", and according to this: http://www.esp8266.com/viewtopic.php?p=2096#p2112
2 means reset by the reset pin... watchdog would be 4.

Except the wifi example at the end doesn't work anymore, because things got moved around and renamed.
