BleDispatcher

public interface BleDispatcher

Interface used to abstract the use of Bluetooth operations.

Mostly used by KallistoSensors to talk with the remote device.

Methods

disableNotification

boolean disableNotification(UUID serviceUuid, UUID characteristicUuid, BleNotificationListener listener)

Disables notifications of the the characteristic with the passed UUID of the service with the passed UUID.

Parameters

  • serviceUuid – The UUID of the service containing the characteristic that should have its’ notifications disabled.

  • characteristicUuid – The UUID of the characteristic that should have its’ notifications disabled.

  • listener – The listener used in enableNotification(UUID,UUID,BleNotificationListener) call.

Throws

  • BleException – If something went wrong with the BLE communication.

Returns

{code true} if notifications were disabled successfully.

enableNotification
