The present invention discloses a Bluetooth mesh network system having wake-up management mechanism that includes a control node and low power nodes.

The control node further transmits data corresponding to the low power nodes in the wake-up period and the low power nodes is operated in a wake-up state within the wake-up period to receive the data from the control node and is operated in a sleep state outside of the wake-up period.

The provisional node is configured to transmit a connection setting packet to the nodes to control the nodes to establish a coded PHY connection between each two of the nodes such that a packet error rate is smaller than a threshold value when the nodes perform communication when a physical distance between each two of the nodes is larger than a maximum non-coded-PHY communication distance, in which when the nodes establish a non-coded-PHY connection and the physical distance is larger than the maximum non-coded-PHY communication distance, the packet error rate is larger than the threshold value.

The present invention discloses a low power dissipation Bluetooth mesh network system and a communication method thereof. The Bluetooth mesh network system includes a friend node and a lower power node. The friend node operates as a proxy server terminal to perform a proxy server broadcast. The lower power node operates as a proxy client and establishes a connection with the friend node based on a proxy protocol when the proxy server broadcast is received and identified. The friend node further filters out an invalid packet unrelated to the low power node and stores a valid packet related to the low power node so as to transmit the valid packet to the low power node when the low power node switches from a sleep status to a wakeup status.

Low power dissipation Bluetooth mesh network system and communication method

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.
