Arduino UNO + ESP8266 WiFi Shield

Need Help With My Project

I am using Arduino UNO + ESP8266 WiFi Shield to connect to BLYNK but every time it gets stuck at the step while connecting to ssid…
I have tried Serial connection which works fine but in order to implement my project, I need to use ESP8266 with Arduino UNO.
Kindly help me in resolving this issue. Thanks

The SSID and wifi password are both case sensitive. Thave you entered them correctly in your code?

If you have then please show us how you’ve connected your hardware together, post your code (correctly formatted) and explain what you’ve done to ensure that your ESP-01 and Uno are communicating at the same baud rate.

I have already worked with NodeMCU. So, as far as I am concerned the username & password are both fine. Everything is perfect regarding the connection and coding. I think there is an issue in my ESP8266 module. Since I am using this ESP8266 for the first time with Arduino UNO, I don’t know much regarding its working as standalone and as a WiFi shield.
Do I need to update the firmware of ESP8266 or I can directly use it with Arduino UNO again by purchasing a new ESP8266 module?

The ESP8266 needs to be running AT firmware and talking to the Arduino at the correct baud rate.
If you’ve flashed the ESP with custom firmware then you need to re-load the AT firmware.

You set the baud rate of the ESP using an AT command. As you’re using an UNO then you’ll be running SoftwareSerial, which does not work well at anything higher than 9600, so you need to set the ESP to that baud rate and as well as specifying it as the baud rate for your SoftwareSerial port.
