Detailed Description

WiFi network scanner implementation for ESP32.

This class provides WiFi network scanning functionality specifically for ESP32 microcontrollers. Since ESP32's WiFi library doesn't provide native callback support for scan completion, this implementation uses a scheduled task to poll for scan completion and trigger the callback.

Constructor & Destructor Documentation

ESP32WifiScan()

uniot::ESP32WifiScan::ESP32WifiScan ( )

inline

Construct a new ESP32 WiFi scanner.

Initializes the scanner and creates a scheduled task for monitoring scan completion status.

Member Function Documentation

getTask()

TaskScheduler::TaskPtr uniot::ESP32WifiScan::getTask ( )

inline

Get the scan completion monitoring task.

Return values

TaskScheduler::TaskPtr

Pointer to the task that monitors scan completion

Note

This task must be added to a TaskScheduler for the scanner to work properly

isSecured()

static int uniot::ESP32WifiScan::isSecured ( int encryptionType )

inlinestatic

Check if a network uses encryption.

Parameters

encryptionType

The encryption type returned by WiFi scan

Return values

int	1 if network is secured, 0 if open

scanNetworksAsync()

void uniot::ESP32WifiScan::scanNetworksAsync ( std::function< void(int)> onComplete, bool showHidden = false )

inline

Start asynchronous WiFi network scan.

Parameters

onComplete	Callback function called when scan completes with network count
showHidden	Whether to include hidden networks in scan results

Note

The scan completion task will be automatically attached with 500ms interval
