[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 invention discloses a Bluetooth data high-speed transmission method and device based on a BLE standard. The method comprises the steps of obtaining to-be-transmitted Bluetooth data; framing the Bluetooth data to generate at least two data frames according to the BLE standard; and transmitting the at least two data frames to a destination device through at least two data transmission channels, thereby enabling the destination device to recombine the at least two data frames to generate the Bluetooth data after the at least two data frames are received. The Bluetooth data is framed to generate the at least two data frames and the at least two data frames are transmitted through the at least two data transmission channels, so the high-speed transmission of the Bluetoothdata can be carried out through 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 ...
