Re: How to get the total and current stack use for tasks

Hi Leherenn,

The first member of TaskSnapshot_t structure, pxTCB, has the same meaning as the first member of TaskStatus_t, xHandle — both are task handles, or pointers to the task control block. You can use this field to match between TaskSnapshot_t and TaskStatus_t lists.

Re: ESP-NOW specifics

The protocol should be compatible between the ESP8266 and ESP32, so perhaps there is some issue with adding peers or setting up encryption... Do you have a wireless adapter in your PC/laptop which you can switch to monitor mode, and capture the packets with Wireshark? Once you have a packet capture,...

Re: ESP-NOW specifics

Hi daneast, ESP-NOW uses a standard Wi-Fi feature called vendor-specific action frames (which is a type of management frames). Since this is part of Wi-Fi protocol, arbitration with other packets at the physical layer is handled the same way as for other Wi-Fi packets. Management frames have a Frame...

Re: Questions about ESP32-S2

Hi Renato, Yes, you should be able to use the current master branch to build projects for ESP32-S2. The steps for building a project with ESP32-S2 are the same as for ESP32, with the addition of "idf.py set-target esp32s2" step to configure the project for the ESP32-S2 target. See https://docs.espre...

Re: WoWLAN (Wake on Wireless LAN)

To add to what Sprite said, you can get to around 3.5mA average current consumption with automatic light sleep + wifi connection on ESP32, provided that the radio environment is not too bad.

Re: does ESP32-s2 support USB host in future?

Hi nzh912,

We don't have USB Host support for ESP32-S2 yet, but we do plan to develop it. I'll update the thread when we have some specific date or estimate when the feature will be ready.
