Connect wifi with ESP-01 module
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:
to station err
Join AP failure
Would you mind give the solutions for this situation?
Thank you very much.
Do you have AT firmware flashed on ESP8266?
Thank you for your prompt reply.
I will try to update the esp8266 firmware and contact you later.
