how to change to textbox for ssid to combobox? I want to have available network ssid listed in the combobox. So I don't have to type the ssid. I also don't understand this part else { Serial.println("Turning the HotSpot On"); launchWeb(); setupAP(); } Both launchWeb() and setupAP() will call createWebServer(). Isn't that redundant? launchWeb() -> createWebserver() setupAP() -> launchWeb()
Hi, It's working successfully but whats the code if I connect the relay with ESP8266 how can we fetch the request from server to control the relay. Because I use Iot wifi controller app.
thanks, nice tutorial. i convert the code to pyhton3 to use with raspberry pi zero w and work fine to! is better than use BLE to smart wifi configuration. :)
My son just finished his school science project and I don’t want him to go into the code and change the Sid and password. Will this work if He already have the sketch completed
Things will work exactly the same. But since nodemcu is a power hungry device it will consume a lot of power. So better put the nodemcu to deep sleep mode after few intervals.
Hello Sir, can i ask a question about EEPROM?...Can EEPROM store some settings, such as an Buzzer, Flame Sensor , Wifi Details and LED code. Example if our IOT project are lose power and reboot, it can running / working well again or not? like ESP8266 Wifi Module can connect our default Wifi again and also Buzzer, Flame Sensor , LED code function smoothly again or not?. Thanks and easy to understand your video anyway.
@@HowtoElectronics thanks and i forgot 1 more quetions, can ESP8266 Wifi Module power on using powerbank/plug charger only or not ?and we don't want to use usb cable from laptop?
Hi Gefford, you can do this simply by using relay and implementing periodic reset after certain interval. Though this is not exactly what you want but it might solve the issue.
@@HowtoElectronics it take more time to assemble but looks like it can be done only by Nodemcu.. there should be a code on doing this (no connection or router hang up) for 1 min nodemcu trigger command to reboot a router with out using any relay it will straight to the router interfaces command to reset just like resestting router using TELNET in PC
Hey this is nice,,, but how can we make our own like in bolt iot? How to make your own wifi manager? This topic is not discussed anywhere if you make a video on this it will be helpful
Please can someone help me to add eeprom to this code because I tried with it but to no avail. Thanks in avance #include //Create software serial object to communicate with SIM800L SoftwareSerial MySim(D4, D3); //SIM800L Tx & Rx is connected to Arduino #3 & #2 String message; void setup() { //Begin serial communication with Arduino and Arduino IDE (Serial Monitor) Serial.begin(9600); MySim.begin(9600); Serial.println("Initializing..."); delay(1000); MySim.println("AT+CMGF=1"); // Configuring TEXT mode
I am 75 years old, retired Telecom engineer and my hobby is IoT. This is really a wonderful project, can you advice me how to add MQTT Username and Password in the similar way to make it a versatile project for IoT use. Please help me. With Great Regards.

else
{
Serial.println("Turning the HotSpot On");
launchWeb();
setupAP();
}

launchWeb() -> createWebserver()
setupAP() -> launchWeb()
There is an if statement at line 125.... " { " and " } " are missing after this line. Will the if statement work without { ... } ?
Amazing tutorial. Kind regards from Brazil!
Wow you are chingon(Grat in spanish),regards from Mexico!
Hi, after reboot Wifi credentials are lost and you have to configure the connection again. Any hint for a fix?

how delete file on the eeprom?
Hi mister, how if wireless router power cycle off?? Can node mcu reconnect automaticly?? Or nodeMcu shuold be restart??
How to add this to another proiect ?
Great Work Good solution in terms of user perspective
Sir, why All relay HIGH after power cut off
thanks, nice tutorial. i convert the code to pyhton3 to use with raspberry pi zero w and work fine to! is better than use BLE to smart wifi configuration. :)
¿Alguien sabe como podría hacerle para que al momento de resetear el ESP, la EEPROM se limpie??

This should work.
Hi how can I connect this to blynk app
Great video. But I have a problem. That is I couldn't acess my softAP by my browser. It did'n response. How can I fix it ? Thank u
Helpful video 👍 I like it
Hey will this thing work if node mcu is powered with battery?
Things will work exactly the same. But since nodemcu is a power hungry device it will consume a lot of power. So better put the nodemcu to deep sleep mode after few intervals.
Thanks, Man it helped me a lot.
Awesome knowledge

Yes you can store anything in eeprom.

and im so sorry, im newbie
It requires 5V. So you can use 5v supply like power bank, mobile charger or any 5v adapter or a battery.
@@HowtoElectronics Thank you very much sir for reply my comment :)
hello sir.. can you make a code to nodemcu which can auto reboot any router when it hangs up or no internet connection... use only nodemcu and usb

what i mean rebooting not resetting
What is hotissspot ??
Hi, great video. What I need to do if the Wifi network and password are changed? thanks.
i guess you have to go to the IP and enter the ssid and password again

Thankyou so much
Thanks alot
This is good , where we can write our main programe code
Under the setup section and loop section
@@HowtoElectronics can you please provide step details where to write it... as I am new/beginner
@@HowtoElectronics Can you please help me, Please share your mail ID, so that I can share you my code...
Thanks
no hard code doesn't means more secure, so what's the point?
