Abstract
A master device, a slave device, and methods are disclosed. The method is performed by a first slave device connected to a master-slave tree network, comprising: determining whether a beacon has not been received within a predetermined time period; and distributing a first beacon to a second slave device if no beacon has been received within the predetermined time period; wherein for the first slave device to remain in the master-slave-network, a beacon be received by the first slave device within the predetermined time period.
Claims16
A method, performed by a first slave device connected to a master-slave tree network, comprising:
- determining whether a beacon has not been received within a predetermined time period;
- and
- distributing a first beacon to a second slave device if no beacon has been received within the predetermined time period,
- wherein for the first slave device to remain in the master-slave tree network, a beacon be received by the first slave device within the predetermined time period.
A master device, for use in a master-slave tree network, comprising:
- a transceiver, configured to receive an identifier request message comprising a first identifier, wherein the first identifier identifies a first slave device, which is abnormally disconnected from the master-slave tree network;
- and
- a controller, coupled to the transceiver, configured to assign a second identifier to the first slave device in response to the identifier request message;
- wherein the transceiver is further configured to transmit an identifier confirm message comprising the second identifier to the first slave device.
A slave device, connected to a master-slave tree network, comprising:
- a controller, configured to determine whether a beacon has not been received within a predetermined time period;
- and
- a beacon circuit, coupled to the controller, configured to distribute a first beacon to a second slave device if no beacon has been received within the predetermined time period,
- wherein for the first slave device to remain in the master-slave tree network, a beacon be received by the first slave device within the predetermined time period.
