[TMT] - Using The Reset Button Of An ESP8266 As An Input

I think this a great solution to how to force config mode when using the WiFiManager library.

Apologies, I'm a little over the two minute mark here, but I was pretty happy with what I had covered so I thought an extra few seconds would be worth not cutting anything!

Also I upgraded to windows 10 recently and I'm just noticing that I have not increased the font size in the Arduino IDE so its a little small.

To my surprise, this is exactly what I was looking to do for the exact library you used in the example. I haven't tried it out yet, but it seems straight forward. I'm currently designing something for a project and I'm keeping manufacturability (I'm not sure that's a word 🤔) in mind, one less button (well, no buttons actually) means less assembly, at n number of units, that adds up.

I really like your 2 minute tips series - very useful for libraries that might get lost in the shuffle otherwise!

What we really want is to prevent reset when the reset button is pressed. Unlike LGT8F328P, ESP8266 does not allow disabling reset function of the reset button. In LGT8F328P, there is register that you can set a bit to prevent reset when the reset button is pressed.

I think it uses SRAM section .noinit for achieving this purpose.

Edit : I've just checked it : It uses RTC memory, which persists between resets.

Thanks for sharing - exactly what I am looking for. Your github link doesn't exist anymore - can you please update the link to the example?

Hi Brian, mai I know where can I download the example sketch of the double reset to wifi manager you shown in the video? I can't find it in your giythub page

How to send a command from a esp8266 to another esp8266 few kilometres away but connected by wifi internet.?
Application is to start a pump far away from a remote switch ( not from mobile phone).
Thanks in advance.

Has anyone found any way to stash an Integer into that persistent memory? That would be VERY useful!
