step S101: the low-power consumption Bluetooth device monitors the used memory in real time, and updates the connection parameters by using the size relation between the used memory and the memory threshold value, wherein the connection parameters comprise the connection interval and/or the data packet length.
In this embodiment, the memory of the bluetooth low energy device receives data and detects the amount of the used memory thereof, and the bluetooth low energy device actively initiates the update of the connection parameter according to the comparison result between the used memory and the preset memory threshold. The change of the connection parameters is based on the change of the data transmission speed of the Bluetooth central equipment, so as to achieve the purpose of communication flow control.

In this embodiment, the connection interval and the packet length in the connection parameters are two parameters that can be adjusted independently, and both the two parameters can be adjusted simultaneously, or any one of the two parameters can be adjusted independently. The preset parameter change rule is as follows:
the connection interval is theoretically 7.5 ms to 40 s. The connection interval is negotiated by both sides of the connection, and generally, the negotiation interval at high speed may be 7.5 ms to 20 ms, and the negotiation interval at low speed may be 800 ms to 1200 ms.
The packet length that both sides of the connection need to negotiate is 27 to 251 bytes. The high speed may be set to 251 bytes, and the low speed may be set to 27 bytes. The connection interval and the packet length can be adjusted according to the actual scheme requirements.
When the used memory is lower than the first threshold, the cache data is less, the processed data is more, the residual space in the memory is large, and the low-power-consumption Bluetooth device actively initiates the update of the connection parameters according to the connection interval and/or the data packet length negotiated by the two connection parties, namely, the connection interval is reduced and/or the data packet length is increased; when the used memory is higher than the first threshold and lower than the second threshold, the connection parameter is unchanged, when the used memory is increased from being lower than the first threshold to the interval between the first threshold and the second threshold, the connection parameter is kept at the connection parameter updated when the used memory is lower than the first threshold, and when the used memory is decreased from being higher than the second threshold to the interval between the first threshold and the second threshold, the connection parameter is kept at the connection parameter updated when the used memory is higher than the second threshold; when the used memory is higher than the second threshold, the number of the cached data is large, the number of the processed data is small, the remaining space in the memory is small, and the low-power-consumption Bluetooth device actively initiates the update of the connection parameters according to the connection interval and/or the data packet length negotiated by the two connection parties, namely, the connection interval is increased and/or the data packet length is reduced.
In an optional embodiment of the present disclosure, the memory threshold is set according to a memory size of the bluetooth low energy device.
In this embodiment, two memory thresholds are set on the memory block of the bluetooth low energy device, and specific values of the two memory thresholds are set according to the size of the memory. Preferably, one is 0.3 times the memory size as the first threshold, and the other is 0.7 times the memory size as the second threshold. The size of the first threshold and the second threshold is dynamically adjusted according to the amount of the actual memory.
It should be noted that the values of the two memory thresholds can be adjusted according to the characteristics of the actual scheme, and only the first threshold needs to be lower than the second threshold.
In an optional embodiment of the disclosure, the bluetooth low energy device comprises a bluetooth printer and/or a bluetooth data transfer module.

After the Bluetooth low energy device and the Bluetooth center device negotiate the successful connection parameters, the Bluetooth low energy device actively updates the connection parameters, the Bluetooth center device updates the data transmission speed of the Bluetooth low energy device according to the updated connection parameters, and sends data to the Bluetooth low energy device by using the updated transmission speed, the processing speed of the Bluetooth low energy device for receiving the data is not a constant value, the transmission speed of the data of the Bluetooth center device needs to be adjusted according to the data processing speed, so that the situation that the data is transmitted too fast in Bluetooth communication, and the data is lost due to the fact that the data processing of the Bluetooth low energy device is not performed is avoided.
In an optional embodiment of the present disclosure, the specific process of updating the transmission speed of the data by the bluetooth central device according to the updated connection parameter includes, if the updated connection parameter is to reduce the connection interval and/or increase the packet length, increasing the transmission speed of the data according to a corresponding relationship between a preset connection parameter and the transmission speed; and if the updated connection parameters are that the connection interval is increased and/or the data packet length is decreased, reducing the data transmission speed according to the corresponding relation.
In this embodiment, the corresponding relationship between the predetermined connection parameter and the transmission speed is calculated according to the connection interval and the packet length, and the transmission speed can be as low as 27 bytes/sec at the lowest and as high as 50 kbytes/sec at the highest.
It is worth noting that the transmission speed of data in the low power consumption bluetooth communication is related to two connection parameters, namely, a connection interval and a data packet length (MTU), and the two connection parameters can be dynamically negotiated and modified, wherein the shorter the connection interval, the larger the MTU, the higher the transmission speed; the longer the connection interval, the smaller the MTU, and the lower the transmission speed. The connection interval parameter is dynamically adjusted according to the judgment of the step S101.
