Detailed Description

Perform and manage BLE scans.

Scanning is associated with a BLE client that is attempting to locate BLE servers.

Member Function Documentation

setActiveScan()

void BLEScan::setActiveScan

(

bool

active

)

Should we perform an active or passive scan? The default is a passive scan. An active scan means that we will wish a scan response.

Parameters

[in]

active

If true, we perform an active scan otherwise a passive scan.

Returns

N/A.

setInterval()

void BLEScan::setInterval

(

uint16_t

intervalMSecs

)

Set the interval to scan.

Parameters

[in]

The

interval in msecs.

setWindow()

void BLEScan::setWindow

(

uint16_t

windowMSecs

)

Set the window to actively scan.

Parameters

[in]

windowMSecs

How long to actively scan.

start() [1/2]

BLEScanResults BLEScan::start	(	uint32_t	duration,
		bool	is_continue = false,
		uint8_t	maxNumDevices = 0
	)

Start scanning and block until scanning has been completed.

Parameters

[in]	duration	The duration in seconds for which to scan.
[in]	is_continue	are we continue scan (true) or we want to clear stored devices (false)
[in]	maxNumDevices	The maximum device number of scan result. If the number of scanned devices reaches maxNumDevices, the scan is stopped and scanCompleteCB is called directly. If 0 (default), there is no limit.

Returns

The BLEScanResults.

start() [2/2]

bool BLEScan::start	(	uint32_t	duration,
		void(*)(BLEScanResults)	scanCompleteCB,
		bool	is_continue = false,
		uint8_t	maxNumDevices = 0
	)

Start scanning.

Parameters

[in]	duration	The duration in seconds for which to scan.
[in]	scanCompleteCB	A function to be called when scanning has completed.
[in]	is_continue	are we continue scan (true) or we want to clear stored devices (false)
[in]	maxNumDevices	The maximum device number of scan result. If the number of scanned devices reaches maxNumDevices, the scan is stopped and scanCompleteCB is called directly. If 0 (default), there is no limit.

Returns

True if scan started or false if there was an error.

stop()

void BLEScan::stop

(

)

Stop an in progress scan.

Returns

N/A.
