I send the AT-CWLAP command to my ESP01 module, but it returns the same command without any network detected.

First I set the module to mode 1 (client mode) with AT+CWMODE=1, then I enter the command AT+RST, and finally AT+CWLAP.

I'm using a Nucleo board to communicate with it. Because of power issues I decided to use an external power supply, but nothing changed.

Finally I solved the problem. The problem was related to a poor stability of the power supply, to solve it I added a 220uF capacitor between Vcc and GND. Since in the communication manager I created I set a timer that stops the communication between my board and the chip if it lasts too long, I also incremented that timer for operation that requires wifi.
