ESP32-H2: Support for IP over BLE

Hi ESP team, ESP32-H2 is exciting device. Simple and low power. Do we plan to support IP over BLE for this device to connect it to internet? Like IPSP? If yes, can smartphone be use as gateway to the internet? At the moment to connect device to internet we need to setup smartphone as Access Point to...

Re: Power consumption for Rainmaker [IDFGH-5540]

The option, ESP_WIFI_STA_DISCONNECTED_PM_ENABLE, could let chip go sleep at disconnected, otherwise chip would stay RX mode and keep current about 100mA even when its not about to connect. However, it could do nothing to decrease consumption at scaning. We are not able to do duty cycling in esp_wif...

Re: Power consumption for Rainmaker [IDFGH-5540]

Hi, thanks for your questions. For your first question, if you want to scan for AP when connected with AP, there is no other specific way to control it. You may need to call scan API periodically to control power consumption. Meanwhile, if you want to scan at disconnected status, please update your...

Re: Power consumption for Rainmaker

Hi fasani, Thank you for your answer. I'm sure that the average current can be reduced. If the searching for AP consumes 80mA we can run it each second and stop after 100-200ms. This will cause some degradation in the AP connection time, but this the acceptable trade-off for me. I just looking for a...

Re: Power consumption for Rainmaker

Hi ESP-IDF team,

Could you please comment how to reduce the current consumption when ESP32S2 is searching for an AP?
I need to add some duty cycling to this process to keep average current in 10-20mA in this mode.

Power consumption for Rainmaker [IDFGH-5540]

Hi Espressif, I tested power consumption of a board with ESP32S2 with simple Rainmaker app running. Only ESP32S2 consumption were measured, no additional electronics added. My results is the following: * ESP32S2 connected to WiFi, connected to cloud and idle: ~30mA * ESP32S2 is looking for an access...

Waterproof touch

Hi Espressif, I want to make a waterproof touch button. I read this https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-reference/peripherals/touch_pad.html article where touch_pad_waterproof API mentioned. Also I read this article https://github.com/espressif/esp-iot-solution/blob/mas...
