US 11,445,440 B2 · Bluetooth mesh network system and connection method having power management mechanism

Abstract

The present disclosure discloses a Bluetooth mesh network system having power management mechanism that includes low power nodes and a friend node. The friend node operates a part of the low power nodes under a first connection mode to establish a one-to-one connection with the friend node under a connection protocol. The friend node operates the other part of the low power nodes under a second connection mode to establish a many-to-one connection based on a broadcast protocol. The friend node sets a mode operation time threshold value and accumulates a mode connection time for each of the low power nodes. When the mode connection time of one of the low power nodes that operates under one of the first connection mode and the second connection mode reaches the corresponding mode operation time threshold value, the one of the low power nodes switches to operate under the other one of the first connection mode and the second connection mode.

Dependent claims

A Bluetooth mesh network system having power management mechanism, comprising:

a plurality of low power nodes (LPN);
and
a friend node configured for:
operating a part of the low power nodes in a first connection mode to establish a one-to-one connection with the friend node based on a connection protocol;
operating the other part of the low power nodes in a second connection mode to establish a multiple-to-one connection with the friend node based on a broadcast protocol;
and
setting a mode operation time threshold value for each of the low power nodes and accumulating a respective mode connection time for each of the low power nodes;
wherein when the mode connection time that the low power nodes operate in one of the first connection mode and the second connection mode reaches the corresponding mode operation time threshold value, the low power nodes switches to operate in the other one of the first connection mode and the second connection mode, in which an average power dissipation of each of the low power nodes is the same according to the mode operation time threshold value set by the friend node.
