AutoConnect VS ESP8266_RTOS_SDK

And for Wifi management on ESP32, this awesome repo that "does it all": https://hieromon.github.io/AutoConnect/ -- this repo creates its own access point you can connect to with your phone to pop-up a "captive portal" (like you see at hotels or airports) to enter your own Wifi credentials -- this is only done once -- after that, the ESP32 will connect to the last known good Wifi network. If you don't want that, just use the built-in Wifi functions to create a local Wifi hotspot to connect to. Then creating web pages on the ESP32 is easy -- you can use the "PageBuilder" JSON syntax, or host regular HTML/JS/CSS files on the SPIFF/LittleFS partition and server those in response to incoming requests.

Or if you don't want to have a hardcoded ssid and password in your program, you can use the AutoConnect library

I want the device to be portable, so I want the esp32 to automatically reconnect to Wi-Fi every time I switch it off and back on. I have used this library, and it serves the exact purpose of what I want to do in my project : https://github.com/Hieromon/AutoConnect

I want to save power on a battery powered sensor but I also want to have AutoConnect set up to set up and configure the wifi. Since having the wi-fi running it can take up a lot of energy I would like to make sure that none of the battery is used during the programming set up. I was thinking that the AutoConnect would only run when it detects that it is plugged into a 5v usb port. I also want a switch so that the usb can power either the sensor (lower power) or the wifi configuration (high power) parts of the program. How would I best accomplish this?

It is this one right: https://github.com/Hieromon/AutoConnect ?

I was using the ESP8266 RTOS SDK (https://github.com/espressif/ESP8266_RTOS_SDK) and using the smartconfig example (https://github.com/espressif/ESP8266_RTOS_SDK/tree/master/examples/wifi/smart_config) with my iOS app. On the mobile side, I was using the EspressifTouchSDK 1.1.0 (https://github.com/EspressifApp/EsptouchForIOS). Basic need was to transfer WiFi SSID - Password to the Esp from the mobile and smartconfig achieved this fast & easy without hassle.

Imagine my disappointment after working on a statically allocated HTTP server stack to discover that even `esp_log.h` does several malloc() calls [1] per log output line... thankfully that was only on the ESP8266_RTOS_SDK, and esp-idf isn't quite as bad.

Maybe this is what they are referring to: https://github.com/espressif/ESP8266_RTOS_SDK/tree/d47d527e0502595700db7b8c468a691c537f6d0b/examples/wifi/smart_config

Don't all legal documents do? I am not a lawyer of any sort (tho have worked with typing things for a firm) and I tried my best, using an example from this

1) The first one is the ESP8266 rtos sdk ( https://github.com/espressif/ESP8266_RTOS_SDK ) I wouldnt recommend this approach for you, as you already work with an Arduino libraries. So with the bare esp8266 rtos sdk you have to do more to achieve your goal.
