1. A Bluetooth mesh network system having wake-up management mechanism, comprising:
a control node configured to keep broadcasting a wake-up parameter setting packet at broadcast time spots based on a broadcast period, wherein the control node operates according to a power from a stable power source and is kept in a wakeup state; and
a plurality of low power nodes each operating according to a power from an unstable power source and configured to receive the wake-up parameter setting packet only from the control node to be operated in a wake-up management mode, to set a start time spot, a time length and a period interval length of a wake-up period that is synchronous among the low power nodes according to the wake-up parameter setting packet;
wherein the control node is further configured to transmit data corresponding to the low power nodes in the wake-up period, and each the low power nodes is periodically 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.
