Abstract

Provided are a data communication method and system, an electronic device, a chip and a storage medium. The data communication method includes: establishing a wireless communication connection with a first receiving terminal, and notifying the connection information to a second receiving terminal. The connection information includes information of a communication channel for performing wireless communication between the transmitting terminal and the first receiving terminal. The connection information is used to instruct the at least one second receiving terminal to monitor communication data in the communication channel. When the at least one second receiving terminal knows after monitoring the communication data, data required to be transmitted to the first receiving terminal is transmitted to the communication channel. A first time period for the transmitting terminal to transmit data in the communication channel does not overlap a second time period for the at least one second receiving terminal to transmit data in the communication channel.

First claim

What is claimed is:

1. A data communication method, applied to a transmitting terminal, comprising:
notifying connection information to at least one second receiving terminal after establishing a wireless communication connection with a first receiving terminal;
wherein the connection information comprises information of a communication channel for performing wireless communication between the transmitting terminal and the first receiving terminal; the connection information is used to instruct the at least one second receiving terminal to monitor communication data in the communication channel, to enable the at least one second receiving terminal to transmit data required to be transmitted to the first receiving terminal to the communication channel when the communication data is known after monitoring by the at least one second receiving terminal; and
wherein a first time period for the transmitting terminal to transmit data in the communication channel does not overlap a second time period for the at least one second receiving terminal to transmit data in the communication channel.

2. The data communication method according to claim 1 , after the notifying the connection information to the at least one second receiving terminal, further comprising:
transmitting data to the first receiving terminal through the communication channel in the first time period;
wherein the connection information is used to instruct the at least one second receiving terminal to monitor data transmitted from the transmitting terminal in the communication channel, to enable the at least one second receiving terminal to transmit data required to be transmitted to the first receiving terminal to the communication channel within the second time period when the data transmitted from the transmitting terminal is known after monitoring by the at least one second receiving terminal; and
wherein the data required to be transmitted to the first receiving terminal is used to indicate whether the data transmitted from the transmitting terminal and known after monitoring by the second receiving terminal is correct.

3. The data communication method according to claim 2 , wherein the data transmitted from the transmitting terminal is data to be synchronized, and the data communication method further comprises:
determining that the first receiving terminal and the at least one second receiving terminal complete data synchronization, when a confirmation message transmitted from the first receiving terminal is received;
wherein the confirmation message is a message transmitted from the first receiving terminal when a preset condition is met; the preset condition is that the first receiving terminal receives preset data from the at least one second receiving terminal and that the first receiving terminal determines that the received data to be synchronized is correct, the preset data being used for indicating that the data to be synchronized known after monitoring by the at least one second receiving terminal is correct.

4. The data communication method according to claim 1 , wherein the communication channel for performing wireless communication between the transmitting terminal and the first receiving terminal comprises: a first communication channel and a second communication channel;
wherein the first communication channel is a communication channel for the transmitting terminal to transmit data to the first receiving terminal, and the second communication channel is a communication channel for the first receiving terminal to transmit data to the transmitting terminal.
wherein information of the communication channel for performing wireless communication between the transmitting terminal and the first receiving terminal comprises: a communication frequency of the first communication channel and a communication frequency of the second communication channel.

5. The data communication method according to claim 1 , wherein the first time period and the second time period are acquired through a preset time slice division, and the preset time slice is a time slice predetermined for the first receiving terminal to receive data; the preset time slice is determined according to a communication protocol that the transmitting terminal and the first receiving terminal are based on when establishing the wireless communication connection.

6. The data communication method according to claim 5 , wherein the wireless communication connection established between the transmitting terminal and the first receiving terminal is a wireless communication connection established based on a preset proprietary protocol;
a duration of the preset time slice is determined according to the number of terminals in the at least one second receiving terminal, and the greater the number of terminals in the at least one second receiving terminal, the longer the second time period obtained through the preset time slice division.

7. The data communication method according to claim 1 , wherein there are N receiving terminals in the at least one second receiving terminal, N being a natural number greater than 1;
wherein the connection information is used to instruct the N second receiving terminals to monitor communication data in the communication channel, and to enable the N second receiving terminals to transmit data required to be transmitted to the first receiving terminal to the communication channel in a preset order.

8. The data communication method according to claim 1 , wherein the wireless communication connection is a Bluetooth connection; and the notifying the connection information to the at least one second receiving terminal comprises:
notifying the connection information to the at least one second receiving terminal through broadcasting.

9. The data communication method according to claim 1 , wherein the transmitting terminal and the at least one second receiving terminal are configured to transmit data to the first receiving terminal through a same communication channel.

10. A data communication method, applied to a first receiving terminal, comprising:
notifying connection information to at least one second receiving terminal after establishing a wireless communication connection with a transmitting terminal;
wherein the connection information comprises information of a communication channel for performing wireless communication between the transmitting terminal and the first receiving terminal; the connection information is used to instruct the at least one second receiving terminal to monitor communication data in the communication channel, to enable the second receiving terminal to transmit data required to be transmitted to the first receiving terminal to the communication channel when the communication data is known after monitoring by the at least one second receiving terminal; and
wherein a first time period for the first receiving terminal to receive data transmitted from the transmitting terminal does not overlap a second time period for receiving data transmitted from the at least one second receiving terminal in the communication channel.

11. The data communication method according to claim 10 , wherein the wireless communication connection is a Bluetooth connection; and the notifying the connection information to the at least one second receiving terminal comprises:
notifying the connection information to the at least one second receiving terminal through broadcasting.

12. The data communication method according to claim 10 , wherein the first receiving terminal receives data from the transmitting terminal and the at least one second receiving terminal through a same communication channel;
wherein the data requir
