in step S101, when a bluetooth connection success is detected, a transmission slot or a reception slot of bluetooth is determined.
The bluetooth is specifically a bluetooth device composed of bluetooth devices, including an electronic device with a bluetooth function. Specifically, when it is detected that the bluetooth device is successfully connected, the bluetooth device is connected with other bluetooth devices to form a piconet, and since one piconet includes one master device and one or more slave devices and a time slot is determined according to the master device, when it is detected that the bluetooth device is successfully connected, it is determined whether the bluetooth device is the master device, when the bluetooth device is the master device, the time slot is numbered and circulated according to a local clock of the bluetooth device, it is determined that a start time of a transmission time slot of the bluetooth device is a start time of an even time slot, a start time of a reception time slot of the bluetooth device is a start time of an odd time slot, and when data transmission and reception are performed, the start time of the data transmission and reception is synchronized with the start time of the time slot.
When the Bluetooth device is a slave device, in order to ensure the transceiving synchronization and the frequency hopping synchronization with the master device, an offset is added into a local clock of the Bluetooth device to realize the synchronization. Further, the starting time of the sending time slot of the Bluetooth device is determined to be the starting time of the odd time slot according to the time slot determined by the main device, and the starting time of the receiving time slot is determined to be the starting time of the even time slot.

It should be noted that the transmission time slot refers to a time interval during which the transmission module is connected to the bluetooth data memory and transmits data successfully through the bluetooth data memory. The receiving time slot is a period of time interval during which the receiving module is connected with the Bluetooth data memory and successfully receives information through the Bluetooth data memory.

Recording the historical time difference from the time when the connection switch starts to connect the transceiver module to the time when the transceiver module starts to transmit and receive signals each time, defining the historical time difference as the reaction time of data transmission and reception, and determining the corresponding preset time according to the reaction time.
In some embodiments, the reaction time may be arithmetically averaged to obtain a corresponding preset time.
In step S103, the connection switch is controlled to be connected to the transceiver module by a preset time before the transmission timeslot or the reception timeslot comes, so that the bluetooth data memory is connected to the transceiver module.
When receiving a data transceiving instruction, the method can determine the starting time point of a transmitting time slot or a receiving time slot according to a local clock of the main equipment, determine the starting time point of the nearest transmitting time slot or receiving time slot, and control the connection switch to be connected with the transceiving module by presetting time in advance before the transmitting time slot or the receiving time slot arrives, so that the Bluetooth data memory is connected with the transceiving module by presetting time in advance.

Therefore, the transceiver module and the Bluetooth data memory are connected before the sending time slot or the receiving time slot arrives, the waiting time for connecting the Bluetooth data memory when the Bluetooth receives or sends data is saved, and the data transmission efficiency is improved.
Referring to fig. 3, fig. 3 is another schematic structural diagram of a bluetooth device according to an embodiment of the present disclosure, the bluetooth device 10 includes a bluetooth data memory 110, a connection switch 120 and a transceiver module 130, the connection switch 120 is used for connecting the bluetooth data memory 110 with the transceiver module 130, the transceiver module 130 includes a receiving module 1302 and a sending module 1304, please refer to fig. 4 at the same time, fig. 4 is another schematic flow chart of a bluetooth memory sharing method according to an embodiment of the present disclosure, and the bluetooth memory sharing method includes:
in step S201, when detecting that the bluetooth connection is successful, a transmission slot or a reception slot of bluetooth is determined.
When the Bluetooth device is detected to be successfully connected, determining whether the Bluetooth device belongs to a master device, and when the Bluetooth device is the master device, numbering and circulating time slots according to a local clock of the Bluetooth device, determining that the starting time of a sending time slot of the Bluetooth device is the starting time of an even time slot, determining that the starting time of a receiving time slot of the Bluetooth device is the starting time of an odd time slot, and synchronizing the starting time of data receiving and sending with the starting time of the time slots; when the Bluetooth device is a slave device, in order to ensure the transceiving synchronization and the frequency hopping synchronization with the master device, an offset is added into a local clock of the Bluetooth device to realize the synchronization.
Further, the starting time of the sending time slot of the Bluetooth device is determined to be the starting time of the odd time slot according to the time slot determined by the main device, and the starting time of the receiving time slot is determined to be the starting time of the even time slot. It should be noted that the bluetooth frequency hopping rate is 1600 times/second, and the duration of each frequency is 625 microseconds, which is called a time slot. In the process of sending data through Bluetooth, the receiving and sending starting time of a data packet is synchronous with a time slot, and one data packet is allowed to occupy 1-5 time slots for sending and receiving. For example, when data is transmitted by the bluetooth transmission module, the transmission time slot is 1865 microseconds, at this time, the data packet occupies 3 time slots 1875 microseconds to transmit the data, and after the transmission time slot 1865 microseconds ends, the connection switch is controlled to disconnect from the transceiver module.
In step S202, a connection state of the connection switch and the transceiver module is detected, and when the connection switch and the transceiver module are detected to start connecting, a current time is recorded as a first time, where the transceiver module includes a transmitting module and a receiving module.
Referring to fig. 3, the connection state between the connection switch 120 and the transceiver module 130 is detected, and when the connection switch 120 is connected to the connection end of a1 or the connection end of a2, the connection switch 120 is connected to the receiving module 1302 or the transmitting module 1304, respectively; when the connection switch 120 is connected to the B connection terminal, the connection switch 120 and the transceiver module 130 are in a disconnected state, and when it is detected that the connection switch 120 starts to be connected to the a1 connection terminal or the a2 connection terminal, that is, when the connection switch 120 is turned from the B connection terminal to the a1 connection terminal or the a2 connection terminal, the current time is recorded as the first time.
In step S203, the transmission power of the transmission module and the strength of the signal received by the reception module are detected to determine the transmission/reception state of the signal.
When the sending module sends a signal, the sending power of the sending module changes to a certain extent, and at the moment, the sending power of the sending module is detected, and the sending state of the signal is determined according to the change of the sending power. Meanwhile, when the receiving module receives a signal, the strength of the signal received by the receiving module changes to a certain extent, and the strength of the signal received by the receiving module is detected to determine the receiving state of the signal.
In step S204, when it is detected that the transmission power of the transmission module is greater than the preset value, it is determined that the transmission module starts to transmit signals through the bluetooth data memory.
When the transmitting power of the transmitting module is detected to be larger than the preset value, the transmitting module is connected with the Bluetooth data memory through the connecting switch, at the moment, a path from the Bluetooth transmitting module to the Bluetooth special data memory is ready, and the transmitting module starts to transmit signals through the Bluetooth data memory.
In step S205, when it is detected that the strength of the signal received by the receiving module is greater than the predetermined value, it is determined that the receiving module starts to receive the signal through the bluetooth data memory.
When the intensity of the signal received by the receiving module is detected to be larger than the preset value, the receiving module is connected with the Bluetooth data memory through the connecting switch, at the moment, the access from the Bluetooth receiving module to the Bluetooth special data memory is ready, and the receiving module starts to receive the signal through the Bluetooth data memory.
In step S206, when it is detected that the transceiver module starts to transceive signals, the current time is recorded as the second time.
When the sending module is detected to start sending signals or the receiving module starts receiving signals, for example, when the strength of the signals received by the receiving module is detected to be greater than a preset value, recording the current time as second receiving time; and when the transmitting power of the transmitting module is detected to be larger than the preset value, recording the current time as a second transmitting time.
In step S207, a historical time difference is determined from the first time and the second time, the historical time difference comprising a historical transmission time difference and a historical reception time difference.
The historical time difference may be determined according to a difference between the first time and the second time, for example, the sending time difference may be determined according to a difference between the sending first time and the sending second time, and specifically, the sending first time is subtracted from the sending second time to obtain the sending time difference.
In step S208, the historical time difference is arithmetically averaged to obtain a preset time, wherein the preset time includes a preset sending time and a preset receiving time.
The sending historical time difference is subjected to arithmetic mean to obtain preset sending time, and the receiving historical time difference is subjected to arithmetic mean to obtain preset receiving time. For example, the historical time differences from the time when the connection switch starts to connect the transmission module to the time when the transmission module starts to transmit the signal are recorded as 0.12 second, 0.14 second and 0.13 second respectively, and at this time, the preset transmission time obtained by arithmetically averaging the historical transmission time differences is 0.13 second. Correspondingly, the historical time difference from the time when the connecting switch starts to connect the receiving module to the time when the receiving module starts to receive the signal is recorded to be 0.2 second, 0.24 second and 0.24 second respectively, and at the moment, the arithmetic mean is obtained according to the historical receiving time difference to obtain the preset receiving time of 0.23 second.
In step S209, the connection switch is controlled to connect with the transceiver module by a preset time before the transmission timeslot or the reception timeslot comes, so that the bluetooth data memory is connected with the transceiver module.
When receiving a data transceiving instruction, the method can determine the starting time of a transmitting time slot or a receiving time slot according to a local clock of the main equipment, determine the starting time of the nearest transmitting time slot or receiving time slot, and control the connection switch to be connected with the transceiving module by presetting time in advance before the transmitting time slot or the receiving time slot arrives, so that the Bluetooth data memory is connected with the transceiving module by presetting time in advance. For example, please continue to refer to fig. 3, when receiving a data transmission instruction, the preset transmission time is obtained as 0.13 second, the starting time point of the latest transmission timeslot is determined, and the connection between the connection switch 120 and the connection end of a2 is controlled 0.13s before the transmission timeslot arrives, so as to ensure the connection between the connection switch 120 and the transmission module 1304, so that the transmission module 1304 is connected to the bluetooth data memory 110, and thus data is transmitted through the bluetooth data memory 110.
In some embodiments, after the step of controlling the connection switch to connect with the transceiver module by a preset time before the transmission timeslot or the reception timeslot comes, and connecting the bluetooth data memory with the transceiver module, the method further includes:
and after the sending time slot or the receiving time slot is finished, the connection switch is controlled to be disconnected with the transceiving module.
Referring to fig. 3, after the transmission time slot or the reception time slot is over, that is, after the transceiver module 130 completes the data transmission and reception through the bluetooth data memory 110, the connection switch 120 is controlled to be connected to the B connection terminal, so as to disconnect the connection switch 120 from the transceiver module 130. For example, when the bluetooth transmission module 1304 transmits data, the transmission time slot is 1865 microseconds, at this time, the data packet occupies 3 time slots 1875 microseconds to transmit data, and after the transmission time slot 1865 microseconds ends, the connection switch 120 is controlled to disconnect from the transmission module 1304.
In step S210, data is transmitted and received through the bluetooth data memory.
After the transceiver module is connected with the Bluetooth data memory through the connecting switch, the transceiver module sends data to the Bluetooth data memory, or receives data through the Bluetooth data memory to complete data transceiving.
