Good point about encryption, so we're looking for the following features of a captive portal:

- encrypted connection, HTTPS
- fully compatible with/ built for the current esp_edf ESP32 release (FreeRTOS)
- image files, css
- ability to enter data in a field and store it in NVS

It appears multiple people looking for a captive portal for ESP32... if someone can create and share a good working example of a captive portal with the following features: - fully compatible with/ built for the current esp_edf ESP32 release (FreeRTOS) - image files, css - ability to enter data in a...

Blue NOA board is disconnected on the picture with 9uA measurement. ESP32 is just not fully visible on the photo, because it's a side view - ESP32 mounted on a small PCB with battery handlers and powered by 3.2v LiFePO4.

Cornelis, any chance you can share the complete example code? github?

I'm looking for the same example - captive portal on ESP32.

There are some examples for esp8266 with Arduino core, but that may not be compatible with ESP32. There is a great example of OpenSSL web server, but how to set it up so it works as a captive portal? Is that even possible?

From your last set of pictures I see that 9uA and 32uA values were obtained from different boards. Are these boards using the same flash chips? If you flash same board with two different firmwares, do you still get this difference? I'll do some measurements by the end of next week, don't have the r...

Can somebody else measure power consumption in deep sleep mode? I'm really curious what's going on...

More pictures to compare power consumption in deep sleep mode: 1. This is the board, which has been programmed using Dec'16 toolchain & esp_idf framework http://i.imgur.com/prV6MfG.png 2. This is the board, which has been programmed with hello_world deep sleep example (above) and the most recent too...

Powering down all peripherals doesn't help. It still draws about 32uA , here is the code I'm testing: #include <stdio.h> #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "esp_system.h" #include "nvs_flash.h" #include "esp_deep_sleep.h" void hello_task(void *pvParameter) { printf("H...

I have a small device, which I programmed about a month ago. That device draws about 9.6uA in deep sleep mode. It goes to a deep sleep by one single command: esp_deep_sleep_start(); Today I updated ESP_IDF toolchain and the distributive code from github and realized, that the same code(!) on the sam...
