WINC3400 OTA Firmware Upgrade Example - SAMD21 XPlained Pro Documentation

Introduction

This example demonstrates the use of the WINC3400 with the SAM Xplained Pro board to perform an OTA Firmware upgrade. It uses the following hardware:

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

Main Files

• main.c : Initialize the WINC3400.

Usage

1. You need to setup an HTTP server accessible via your Wi-Fi network. This HTTP server must have the "m2m_ota_3400.bin" OTA firmware accessible at this location: http://SERVER_IP_ADDRESS/m2m_ota_3400.bin

Note:

• the OTA firmware file is included in this project under the firmware folder.
• the server IP address must be set via the MAIN_OTA_URL macro from main.h file.

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"
   *     #define MAIN_OTA_URL          "http://192.168.1.11/m2m_ota_3400.bin"
   * 

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
* 

1. Start the application.
2. In the terminal window, the following text should appear:

   *    -- WINC3400 OTA firmware upgrade example --
   *    -- SAMXXX_XPLAINED_PRO --
   *    -- Compiled: xxx xx xxxx xx:xx:xx --
   *    Wi-Fi connected
   *    Wi-Fi IP is 192.168.0.10
   *    OtaUpdateCb 1 0
   *    (APP)(INFO)OTA download succeeded
   *    OtaUpdateCb m2m_ota_switch_firmware start.
   *    OtaUpdateCb 2 0
   *    OTA Success. Press reset your board.
   *
   *
