Re: Need to reduce wifi startup time and power consumption

Wifi is not a technology designed to run on batteries because of its energy consumption, I guess you know that, although optimizing will have problems.

To operate with batteries without solar charger: BLE, LPWAN... etc.

Re: Modem Sleep: Is there any callback?

In this example https://github.com/espressif/esp-idf/tree/master/examples/wifi/power_save they talk about 10s but I don't know how to configure it, if it is possible. Although the idea would be that the chip remains in light sleep mode with the wifi active and wakes up when it receives any data. if ...

Hi, according to esp32_technical_reference_manual_en. pdf is only possible in light sleep mode, table pag 616: 5. To wake up the chip with a Wi-Fi or BT source, the power mode switches between the Active, Modem- and Light-sleep modes. The CPU, Wi-Fi, Bluetooth, and radio are woken up at predetermine...

Re: ESP32 GPIO state at power-on

Maybe this is a clue: Strapping pins When an ESP32 is powered on, we may wish to control/configure how it boots. To achieve this, a set of pins are defined that are read for the very short time that is considered the bootstrap time. For the sake of discussion, we should image this as the instantaneo...

Re: Identify moisture and humidity sensor on ESP32

Hello, I suggest you read a couple of posts about I2Chttp://www.lucadentella.it/en/2017/10/0 ... i2c-basic/ from Lucadentella's blog and use his i2c scanner codehttps://github.com/lucadentella/esp32-t ... 2c_scanner to test your sensor.

Its because there is difference between latest version and latest released version. Latest version is current version that dev team is working on (its version 3.0-pre release), and the latest release version is latest stable version.
Thank you so much for the explanation.
