# Sending AT Commands

Test your SuperB by having it scan for nearby access points.

* **1)** First, follow the instructions [here](/product-documentation/superb-docs/flashing-superb.md) to flash SuperB with the ESP tool.
* **2)** Follow the instructions [here](https://github.com/espressif/arduino-esp32/blob/master/docs/arduino-ide/boards_manager.md) to set up the board manager for ESP32.
* **3)** Connect the SuperB with the USB adapter board and select the correct port.
* **4)** Open the serial monitor, with baud equal to 115200 and both NL and CR set.

* **5)** Hit RESET on the USB adapter board, the SuperB should report back ready.

 Try the following two commands sequentially to get a list of access points visible to the SuperB:

```
 AT+CWMODE=3
 AT+CWLAP
```
