Re: KRAK Attack Vulnerability on WPA2 client-side.

Looks like Espressif had prior disclosure and have already pushed fixes to the master branch of the IDF. They will also soon be releasing v2.1.1 with the fix and it will be in the upcoming v3.0 release. https://esp32.com/viewtopic.php?f=13&t=3349&p=15687#p15687 Epic. I suspected they'd be on top of...

KRAK Attack Vulnerability on WPA2 client-side.

Heads up, folks! https://www.krackattacks.com/ Basically, there's a design flaw in the standard for WPA2 that allows for a key re-installation attack on WPA2. All key exchange types are vulnerable. AES-CCMP is semi-resilliant to the attack, as is Enterprise. TKIP and GCMP are very, very vulnerable. ...

Re: After updating ESP32-IDF through github make clean, make all etc... has stopped to work

Builds for me. Sounds like a messy build environment. You might want to do a "reset --hard HEAD" in the toplevel followed by a "git submodule update --init" to do a bit of housecleaning. I had a lurker on my latest pull where I'd started (but not finished) adding the Zephyr BT stack as an option cho...

Re: ESP-WROOM-32 production capacity

This is very good to know. There's several differing things that I'd honestly like to productize if they turn out as planned (so far, so good...) 1-2 Wk lead isn't too bad for getting product into the shipping/customs channel.

Re: Zephyr support for ESP32

If it's so great, why don't you implement it? If so, great. It'll showcase that you're right and I'm wrong. If not, perhaps you should gain a bit of chops programming at that level before you comment on such things. Someone that HAS that is trying to tell you several somethings...and you blew it off.

Re: Zephyr support for ESP32

Can't be "verifiably" safe in the sense of logic errors. No one in their right mind would claim that. But, you know - I'll take memory safety freedom of data-races guaranteed deadlock free execution over what C and C++ guarantee, which is pretty much nothing. Memory safety is something of a luxury ...

Re: Zephyr support for ESP32

Is there anything out there that can compare to Jorge Aparicio's RTFM? Its IMHO the natural design for memory-constrained devices. Shared memory, multitasking, events, hardware assisted scheduling, verifiably safe by virtue of Rust. Can't be "verifiably" safe in the sense of logic errors. Verifiabl...

Re: Where are esp_wifi_* functions defined?

I suspect that they can Open up the WiFi part, because they own the IP through and through, being a carry over from their prior tech. (If so, please, please, please consider it. It unlocks all sorts of things on the WiFi side of this device.)

Re: Documentation: Where is the in-depth description about timers, CAN?

Technical reference manual, sdk http://espressif.com/en/support/download/overview http://esp-idf.readthedocs.io/en/latest/ Docs are being added and released piece by piece. There are user generated CAN drivers on github. Remind me how many employees and revenue does ST have and what are they chargi...

Re: BLE on ESP32

What are the security protocols used in BLE connection establishement and data transfer? Is it secure channel or not? If not, is there any provision to do so? if it is, where can i find the security implementation? I doubt they've implemented much of any of the security (Or, rather "Security" being...
