Re: Notes on using Windows Subsystem for Linux with ESP-IDF

I have tinkered with it before, and it seemed to work well for me. The only major problem that i encountered is that when cloning all the source code, it needs to be cloned with Linux line endings (yes sounds obvious i know), as i found it would not build with the windows style line endings. (where ...

Re: refresh cache on gatts client

There is a services changed service/characteristic that is provided by the esp32 stack. I am not 100% sure that it is exactly what you are looking for, but from my understanding this can be used to inform a Client that the services have been changed. However since i have never used it i am not sure ...

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...
