Class GattLocalCharacteristic

java.lang.Object
com.codename1.bluetooth.le.server.GattLocalCharacteristic
public class GattLocalCharacteristic extends Object

A characteristic definition of a local GattLocalService served by this device's GattServer. Properties use the

invalid reference 
GattCharacteristic
`.PROPERTY_*` bits; access permissions use the

PERMISSION_* bits defined here.

  • Field Details

    • PERMISSION_READ

      public static final int PERMISSION_READ
      The characteristic may be read (bit 0x01).

    • PERMISSION_READ_ENCRYPTED

      public static final int PERMISSION_READ_ENCRYPTED
      The characteristic may be read over an encrypted link only (bit 0x02).

    • PERMISSION_WRITE

      public static final int PERMISSION_WRITE
      The characteristic may be written (bit 0x10).

    • GattLocalCharacteristic

      public GattLocalCharacteristic(BluetoothUuid uuid, int properties, int permissions)

      Creates a characteristic definition. properties uses

      invalid reference 
      GattCharacteristic
      `.PROPERTY_*` bits; `permissions` uses the

      PERMISSION_* bits of this class.

  • Method Details

    • setValue

      public GattLocalCharacteristic setValue(byte[] staticValue)
      Serves a static value without routing read requests to the GattServerListener. Without a static value, every read arrives as a GattReadRequest.

    • addDescriptor

      public GattLocalCharacteristic addDescriptor(GattLocalDescriptor d)
      Adds a descriptor definition.

    • getUuid

      public BluetoothUuid getUuid()
      The UUID identifying this characteristic.

    • getProperties

      public int getProperties()

      The

      invalid reference 
      GattCharacteristic
      `.PROPERTY_*` bitmask.

    • getPermissions

      public int getPermissions()
      The PERMISSION_* bitmask.

    • getValue

      public byte[] getValue()
      The static value, or null when reads are served via the GattServerListener.

    • getDescriptors

      public List<GattLocalDescriptor> getDescriptors()
      The descriptor definitions added via addDescriptor(GattLocalDescriptor).

    • toString

      public String toString()
      Description copied from class: Object
      Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method. The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: getClass().getName() + '@' + Integer.toHexString(hashCode())
      Overrides:
