Overview

The CC3200 allows users to set a scan policy and enable scanning. sl\_WlanPolicySet API can be used to set the scan policy to SL_POLICY_CONNECTION, SL_POLICY_SCAN or SL_POLICY_PM. Once the scan cycle is enabled and set, sl_WlanGetNetworkList API can retrieve the results of the scan. It provides the RSSI (Received Signal Strength Indication), security information, BSSID, and SSID.

Application details

This example demonstrates how scan policy is set in the device. The procedure includes the following steps:

• Check the connection policy is not set (so no scan is run in the background)
  
• Enable scan, set scan cycle to 10 seconds and set scan policy. This starts the scan.
• Get scan results, all 20 entries in one transaction
  
• Get scan results, 4 transactions of 5 entries
  
• Disable scan

Source Files briefly explained

• main.c - The main file that explains steps to set scan policy, enables scan and gets the scan result
  
• pinmux.c - Generated by the PinMUX utility
• startup_*.c - Initialize vector table and IDE related functions
• gpio_if.c - GPIO Interface APIs

Usage

1. Run the reference application.
   • Open the project in CCS/IAR. Build the application and debug to load to the device, or flash the binary using UniFlash.
2. The application scans and retrieves the network list. lRetVal indicates the number of networks found (or error) and netEntries contains the network list.
   
3. The orange LED on the LaunchPad will turn on in case of an error. The green LED will turn on upon successful execution.
