The invention discloses a method for adaptively updating a receiving window of
Bluetooth slave equipment, and the method comprises the following steps: opening the receiving window, setting the starting point moment of a connection event in each receiving period as T2, enabling the T2 moment to be interrupted, and allocating a counter with an initial value of N to the T2 moment; judging whether the numerical value in the counter is 0 or not when interruption is generated at each T2 moment, and if not, subtracting 1 from the numerical value in the counter; if so, closing the receiving window; in the
window period of the receiving window, receiving the
demodulation completion
signal through the
baseband and judging the numerical value in the counter at the current moment, if the numerical value is 0 or N, updating the
clock parameter of the current slave device, and aligning the starting point moment of the connection event with the starting point of the current data packet; otherwise, directly receiving the data packet and decoding the data. According to the method, a receiving window of the
Bluetooth slave device is arranged, so the problem of unstable connection of the low-power-consumption
Bluetooth slave device is solved; by dynamically adjusting the opening time of the receiving window, the stability of the slave device is improved, the windowing time is reduced as much as possible, and
power consumption is reduced.
