Re: WiFi WPA2 protocol vulnerabilities (VU#228519)

@Ritesh

Espressif have a path forward for you for this. They have released v2.1 (and soon to have v2.1.1).
This should essentially be v2.0 with the bugfixes you are looking for.

Re: Antenna matching network on ESP32-PICO-D4

Antenna matching is very dependant on your specific board and board design, hence the TBD values. (edit: i realise this paragraph relates to the normal esp32 chip and not the pico-d4) A 50ohm antenna is not a perfect match for what the ESP32 outputs, i belive is it something like 30+ j??. However it...

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.

Re: Tickless Idle with Light sleep

Thanks for the quick reply @ESP_iggr. Sounds great! A couple more questions: - With the changes that are coming next week (ish) to reduce the system clocks for sleeping, will this work with BLE to improve power consumption? - With the automatic light sleep that is currnetly in the works, i take it t...

Tickless Idle with Light sleep

Hi Espressif folks, Just wondering if tickless idle support (with automatic entry and exit of light sleep) is planned (or already implemented) in the IDF? It would be good it we could get an estimated IDF version in which this might be implemented. I am sure this has been discussed internally and is...

Re: Using c++ for ESP32 develpment with ESP-IDF, PlatformIO

@Nkolban has been working with c++ on the esp32 for quite some time. I think he has some guides about setting up the esp32 for c++ development. There is probably some good guides in his book. This is his github where you might be able to find some more information: https://github.com/nkolban/esp32-s...

Re: What would you like to see in The Next Chip?

@permal They can co-exist together. So for example you can have a BLE peripheral connected to a phone with the esp32 as a AP at the same time. This is what we do in on of our applications. It works really well. However since they share the same RF radio they cant transmit/receive at the same time. T...

Re: BLE graceful disconnect problem

Yes I will second that "esp_ble_gattc_close" is the correct function to call to disconnect from a peripheral. The register and un-register api calls are to register an application callback with the stack. In my application i register 3 of these (My application can handle up to 3 connected peripheral...

Re: disable brownout detection

Have you tried running a make erase_flash, then re-flashing the firmware onto the esp32?
