Sets an instance of LowpanScanner.Callback to receive events.

Parameters
cb LowpanScanner.Callback

setCallback

void setCallback (Handler handler, 
                LowpanScanner.Callback cb)

Sets an instance of LowpanScanner.Callback to receive events.

Parameters
handler Handler

cb LowpanScanner.Callback

setTxPower

void setTxPower (int txPower)

Sets the maximum transmit power (in dBm) to be used for active scanning.

The actual transmit power used is the lesser of this value and the currently configured maximum transmit power for the interface.

Parameters
txPower int

startEnergyScan

void startEnergyScan ()

Start an energy scan.

This method will return once the scan has started.

Throws
LowpanException

See also:

startNetScan

void startNetScan ()

Start a network scan.

This method will return once the scan has started.

Because performing a network scan will return the hardware addresses of nearby devices, the use of this method requires the permission @{link android.Manifest.permission.ACCESS_COARSE_LOCATION}.

Throws
LowpanException

stopEnergyScan

void stopEnergyScan ()

Stop an energy scan currently in progress.

See also:

stopNetScan

void stopNetScan ()

Stop a network scan currently in progress.
