Problems solved by technology
[0003] At present, due to the limitation of the power consumption of the system, the Bluetooth pen cannot select EDR for high-speed Bluetooth data transmission. Therefore, BLE must be used for high-speed Bluetooth data transmission.
However, when using a Bluetooth pen to write, the data acquired by each set of coordinates exceeds 20 bytes, which is larger than the 20-byte frame requirement specified in the BLE standard. Moreover, when the Bluetooth pen is writing at high speed, every 2ms Scanning a set of data is shorter than the 7.5ms specified by the BLE standard. Therefore, when using BLE for high-speed transmission of Bluetooth data, if the queuing transmission method is used, the real-time meaning will be lost. If the offline queuing low-speed transmission method is used , the transmission time will be very long

The embodiment of the present invention discloses a Bluetooth data high-speed transmission method and device based on the BLE standard, including: acquiring the Bluetooth data to be transmitted; performing frame processing on the Bluetooth data according to the BLE standard to generate at least two data frames; The at least two data frames are transmitted to the destination device through at least two data transmission channels, so that the destination device reassembles the at least two data frames after receiving the at least two data frames to generate the Bluetooth data. At least two data frames are generated by framing the Bluetooth data, and the at least two data frames are transmitted through at least two data transmission channels, so that the high-speed transmission of Bluetooth data can be performed using BLE.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for high-speed transmission of Bluetooth data based on the BLE standard. Background technique [0002] Bluetooth Low Energy (BLE) technology is a low-cost, short-range, interoperable and robust wireless technology that operates in the license-free 2.4GHz ISM radio frequency band. The BLE standard is a low-power Bluetooth product protocol set for small data blocks and low-speed transmission. Many BLE products require a data frame of 20 bytes and a frame interval greater than 7.5ms. The Bluetooth enhanced rate (Enhanced DataRate, EDR) greatly improves the data transmission rate of Bluetooth technology, [0003] At present, due to the limitation of the power consumption of the system, the Bluetooth pen cannot select EDR for high-speed Bluetooth data transmission. Therefore, BLE must be used for high-speed Bluetooth data transmission. However, when using ...
