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.

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 preset 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 second receiving terminal to monitor communication data in the communication channel. When the 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 second receiving terminal to transmit data in the communication channel.

A BLE-based positioning method is applied to a terminal device, and includes: calculating a change rule of the RSSI value when a received signal strength indication (RSSI) value obtained by parsing a received signal of a target BLE slave device is less than a predetermined threshold; and generating prompt information used for prompting a moving direction of the terminal device according to the change rule of the RSSI value until the RSSI value is greater than or equal to the predetermined threshold.
