esp8266 calling out to micropython.org

[jrichard82]

I am seeing some strange behavior on my esp8266. At random hours the board (flashed with the latest version of MicroPython )is calling out to MicroPython.org and sending data to servers in Linode. What is the purpose of this? Is there and option to disable this?

That's quite surprising?

micropython.org is hosted at Linode, and the only thing I can think of is that upip will look for packages at micropython.org. But this would definitely not be happening in the background.

Any chance you have any additional information about what the payloads look like? i.e. is it HTTP, what's the path, subdomain, content?

jimmo, thanks for the response. I think you solved the mystery. I dug through the sources and the only place I saw that was hitting micropython was upip. I went back through my logs and the activity *may* have been associated with a upip install but I can't remember. I havent been seeing the activity today....

Thanks again.
