WiFiManager "on demand" (for configuration only) example

khoih-prog / ESPAsync_WiFiManager

This is an ESP32 (including ESP32-S2 and ESP32-C3) / ESP8266 WiFi Connection Manager, using ESPAsyncWebServer, with fallback web configuration portal. Use this library for configuring ESP32, ESP8266 modules' WiFi, etc. Credentials at runtime. You can also specify static DNS servers, personalized HostName, fixed or random AP WiFi channel. With examples supporting ArduinoJson 6.0.0+ as well as 5.13.5- . Using AsyncDNSServer instead of DNSServer now.

WiFiManager "on demand" (for configuration only) example #72

Closed ClemensGruber closed 2 years ago

ClemensGruber commented 2 years ago

I'm searching for example code that uses WiFi "on demand" for configuration only. Data telemetry is done by GSM (and only optional by Wifi). So the scenario is

Normally Wifi sould be not activated to save power, I have a solar powered device that makes nothing 99 % of the time, that means deep sleep.
But even if the UI and Wifi does not run, I need accesss to the variables modified and configured via the WifiManager.
In case configuration mode / on demand is activated we need a timeout, in case someone forget to disconnect from the the UI the device should stopp the UI and WiFi after a time and go in deep sleep, otherwise the device will run out of battery.

Is there any exampel code for this scenario? I'm a bit confused about the many Async_ConfigOn... examples ...

Hi,

Thanks for your interest and trust in the library. As you know, no library and example is designed to be able to apply in all complex use cases in the world, especially yours.

I'm sorry I won't spend time on this not-issue, unless a library's bug is proven.

I suggest you ask for advice of many experts in Arduino Forum and/or ESP32 / ESP8266 forums

Good Luck,

BTW, have a look at these examples to see if you can use anything

SmartFarm_DeepSleep
Async_ConfigOnSwitchFS where you can replace this following line Async_ConfigOnSwitchFS.ino#L1201 with any condition you'd like to activate Config Portal.

if ((digitalRead(TRIGGER_PIN) == LOW) || (digitalRead(TRIGGER_PIN2) == LOW))

Certainly, your use case requires more careful and complex design and implementation.
