WINC3400 Signal Strength Example - SAMD21 XPlained Pro Documentation

Introduction

This example demonstrates the use of the WINC3400 with the SAMD21 Xplained Pro board to check the signal strength such as RSSI.
It uses the following hardware:

• the SAMD21 Xplained Pro.
• the WINC3400 on EXT1.

Main Files

• main.c : Initialize the WINC3400 and get RSSI for the connected AP.

Usage

1. Configure below code in the config main.h for AP to connect to.

   *    #define MAIN_WLAN_SSID         "DEMO_AP"
   *    #define MAIN_WLAN_AUTH         M2M_WIFI_SEC_WPA_PSK
   *    #define MAIN_WLAN_PSK          "12345678"
   * 

2. Build the program and download it into the board.
3. On the computer, open and configure a terminal application as the follows.

   *    Baud Rate : 115200
   *    Data : 8bit
   *    Parity bit : none
   *    Stop bit : 1bit
   *    Flow control : none
   * 

4. Start the application.
5. In the terminal window, the following text should appear:

   *    -- WINC3400 signal statistics example --
   *    -- SAMD21_XPLAINED_PRO --
   *    -- Compiled: xxx xx xxxx xx:xx:xx --
   *    Wi-Fi connected
   *    Wi-Fi IP is xxx.xxx.xxx.xxx
   *    RSSI for the current connected AP (-48)
   *
