Wi-Fi Scan
=======================================

Project Overview
--------------------------

This project is used for demonstrating [Wi-Fi Scan](https://docs.bekencorp.com/armino/bk7236/en/latest/developer-guide/wifi/bk_wifi_scan.html)

  - This project shows Wi-Fi scan procedure, it scans the APs around and return the results.
  - This project not only supports global scanning, but also can scan by specific SSID.

Hardware Requirements
----------------------------

All Beken development board.

Configure and Build
--------------------------------

Configure the parameter
+++++++++++++++++++++++++++++++

You can configure the scan parameter in projects/examples/wifi/scan/main/Kconfig.projbuild

::

 menu "Example Configuration"

    config EXAMPLE_SCAN_ALL_SSID
        bool "Scan All SSID"
        default y

    config EXAMPLE_WIFI_SSID
        string "WiFi SSID"
	depends on !EXAMPLE_SCAN_ALL_SSID
        default "myssid"
        help
            Set the SSID to be scaned
 endmenu

Build
+++++++++++++++++++++++++++++++

Enter the following command in the Armino root directory to compile:

> make bk7236 PROJECT=examples/wifi/scan

For preparations such as toolchain installation, please refer to [Quick Start](https://docs.bekencorp.com/armino/bk7236/en/latest/get-started/index.html).

Connect UART
++++++++++++++++++++++++++++++++++

UART0 is used for:

 - BKFIL to download images
 - Logging and CLI of Non-secure world

UART1 is used for logging of secure world.

Flash all-app.bin
++++++++++++++++++++++++++++++++++

Burn Armino/build/scan/bk7236/all-app.bin to the board using BKFIL.

Running and Output
----------------------------------

Case 1 - Scan all SSIDs
+++++++++++++++++++++++++++++++++++

Restart the development board to observe the scan process.

Case 2 - Scan specific SSID
+++++++++++++++++++++++++++++++++++

After setting EXAMPLE_SCAN_ALL_SSID to "n" and "myssid" to the specific SSID in Kconfig.projbuild, restart the development board to observe the scan process.
