If this process fails, it sets the ESP into Access Point mode and creates Open Wifi(Not protected with Password).On ESP8266 boot, it is set up in Station mode, and Read the pre-registered SSID and password combination and tries to connect to the same.The Program is designed to follow the below steps.

Program & Source Code: Change ESP8266 WiFi credentials without uploading code

It is also used for users to configure IoT devices for first-time use, or password changes” An access point sometimes connects to a wired router, switch, or hub via an Ethernet cable, and projects a Wi-Fi signal to a designated area. “An access point is a device that creates a wireless local area network. or WLAN, usually in an office or large building. In this process, The target device will first act as an access point and allow us to connect and modify the WiFi credential. The provisioning process involves loading the station with the network name (often referred to as SSID) and its security credentials. Wi-Fi provisioning is the process of connecting a new Wi-Fi device (station) to a Wi-Fi network. Provisioning IoT products, that do not have a keyboard and display as a user interface, in a simple and robust way is a significant challenge. Even all IoT Devices that are available in the market have this WiFi Provisioning Feature. This is why we should have WiFi Provisioning in our solutions.

It also makes your sketches less sharable, as you probably will want to replace your SSID and Password with placeholders before uploading to somewhere public like GitHub and anyone who is using your code is going to have to update the code before they can use it on their network. If you have hard-coded values in your sketch, if you change your WiFi router or want to bring your device to somewhere else, you are going to need to re-program your esp8266, which isn’t ideal!

This tutorial is also available in the video format, You can have look or continue to read. It will only take a couple of minutes to go through these steps Then it connects to the freshly configured WiFi Credentials. We are going to develop an Arduino Program, Which First Reads the WiFi Credentials from the EEPROM, and tries to connect to that If the WiFi is not available or there are no credentials stored in the EEPROM, ESP8266 will Acts an Accespoint and creates Hotspot which will allow us to connect and modify the WiFi credential.

In this article, we are going to walk through ” how to Change ESP8266 WiFi credentials without uploading code from Arduino IDE”, We will update WiFi Credential wirelessly and store the same credentials in the EEPROM memory of the ESP8266 using a really awesome library “ EEPROM.h“. 3 Program & Source Code: Change ESP8266 WiFi credentials without uploading code.
