Bluetooth-based data transmission method and data receiving method, communicating apparatus and computer storage medium

A Bluetooth-based data receiving method applied to a second device, comprising:

• establishing a communication connection with a first device;
• receiving a notification message transmitted by the first device, wherein the notification message comprises indication information of a sniff interval;
• entering a sniff mode;
• and
• receiving a data packet transmitted by the first device in the sniff interval, wherein the transmission duration of the data packet is longer than or equal to two time slots,
• wherein, receiving the data packet transmitted by the first device in the sniff interval comprises:
• starting to receive the data packet transmitted by the first device in an odd time slot of the sniff interval;
• or
• starting to receive the data packet transmitted by the first device in an even time slot of the sniff interval.

A communication device comprising:

• a transceiver configured to establish a communication connection with a second device;
• and
• a processor coupled to the transceiver and configured to perform operations comprising:
• determining a sniff interval;
• transmitting indication information of the sniff interval to the second device through the transceiver;
• entering a sniff mode;
• and
• starting to transmit a data packet to the second device in an even time slot of the sniff interval through the transceiver or starting to transmit the data packet to the second device in an odd time slot of the sniff interval through the transceiver,
• wherein the transmission duration of the data packet is longer than or equal to two time slots.
