To anybody interested in ESP8266 and micopython: https://www.kickstarter.com/projects/214379695/micropython-o...

This resulted recently in this: https://github.com/micropython/micropython/releases/tag/v1.8...

From a humble yet proud backer :)

This is pretty interesting! Do you know if it supports SSL on the ESP8266?

Yes, it should:

Nice a websockets REPL! It would be fun to make this connect to Jupyter/IPython notebooks :)

To anybody interested in ESP8266 and JavaScript, shameless plug: https://github.com/cesanta/mongoose-iot

It can also be used as a replacement SDK for C development. In addition to the stock ESP8266 SDK it offers a filesystem, configuration infrastructure, async networking library (using the github.com/cesanta/mongoose networking library), OTA update support, coredumps, easy to use toolchain based on docker, improved (faster) flashing tool. And you can also enable the JavaScript scripting engine and script your firmware.

We're also supporting other platforms such as the cc3200 so it will enable you to easily change the target; some platforms are good for prototyping, some are better for production; often it's impossible to choose wisely at the beginning so it's nice to not require a full rewrite of your logic.

As someone who uses the CC3200, is your firmware a replacement for the SimpleLink stack?

It uses SimpleLink for lower level protocols (TCP, SSL) but replaces the higher level functionality (HTTP, DNS)

There was an exceptional talk at Thotcon this year on the ESP8266. Amazing work, and clearly a great deal of it, at one point the speaker casually noted that a table of information was not publicly available leaving unsaid what had obviously been months of tedious reversing. Its a shame there are no videos of the talk.

The speaker talked about an exploitable vulnerability in the bootrom, correct? Thus all ESP8266s are permanently vulnerable and only a new die rev could fix it. The CPU architecture is also interesting.

The talk description for "The Complete ESP8266 Psionics Handbook":

"But few realize that beneath the veneer of accessibility lurks a Pandora's box of perils straight out of the 90s... This talk will focus on exploiting memory corruption vulnerabilities for platforms hosted on the ESP8266. This talk will focus on exploiting memory corruption vulnerabilities for platforms hosted on the ESP8266."

The deck is here:

Thank you for the slide deck! I arrived about halfway into the talk and hadn't seen the published slide deck until you pointed it out to me.

yes thanks for this. Hadn't taken the time to hunt it down yet!

I had thought that this might be an announcement about the availability of the ESP32. It is not. It's clickbait about an ESP8266-like chip with some onboard flash memory.

Yeah, probably not an ESP8288 killer. I doubt there are many applications where the size of existing ESP8266 modules is an obstacle but its power consumption is not; the power source it requires is going to be much bigger than the module itself.

Side note: PlatformIO (http://platformio.org/) is awesome and is how I program these chips.

I see the datasheet mentions WiFi Direct and WPS which I remember at some point wasn't possible with the ESP8266. Does this mean that it can be controlled directly by an Android phone with WiFi P2P?
