Connect wifi with ESP-01 module

[meoDz]

Dear all,
I am a newbie with the Sperense board and I would like to connect to wifi by using ESP-01.
I follow this instruction but it did not work.

The error from serial monitor of Arduino IDE:
setup begin
FW Version:
to station err
Join AP failure
setup end
Would you mind give the solutions for this situation?

Thank you very much.

Hi @meodz

Do you have AT firmware flashed on ESP8266?

Hi @meodz

Here you will find information on how to connect your ESP8266 to the terminal program on your PC to check if the ESP8266 has AT command firmware: https://ukhas.net/wiki/esp8266_firmware_update

If not, you can use these instructions to flash the firmware.
