Example 1 with BluetoothLeAdvertiser

use of android.bluetooth.le.BluetoothLeAdvertiser in project android-beacon-library by AltBeacon.

the class BluetoothMedic method runTransmitterTest.

/**
 * Starts up a beacon transmitter with the intent of seeing if it results in an error condition
 * indicating the bluetooth stack may be in a bad state.
 *
 * If the failure error code matches a pattern known to be associated with a bad bluetooth stack
 * state, then the bluetooth stack is turned off and then back on after a short delay in order
 * to try to recover.
 *
 * @return false if the test indicates a failure indicating a bad state of the bluetooth stack
