AI Technical Summary
Technical Problem
The signal quality received or transmitted by multiple antennas in a Bluetooth antenna array affects the accuracy of the positioning angle, resulting in low positioning accuracy.
Method used
By acquiring the sampling IQ data and data signal strength indication from the sampling message, signals with excellent signal quality are selected. The position angle is calculated using methods such as phase compensation processing and weighted averaging, and data with poor signal quality is eliminated, thereby improving positioning accuracy.
Benefits of technology
It improves the accuracy and precision of Bluetooth positioning, ensuring that the final calculated position and angle match the actual situation.

Abstract
本申请提供一种蓝牙定位方法、终端设备、电子设备及存储介质，涉及计算机的技术领域。蓝牙定位方法，包括：获取采样报文，所述采样报文包括采样IQ数据和数据信号强度指示，所述采样IQ数据包括按照预设顺序对蓝牙天线阵列中的多个天线接收或发送的信号依次进行采样得到的多个采样IQ值，所述多个天线接收或发送的信号为同一信号源发送的信号；判断所述数据信号强度指示是否大于预设阈值；若所述数据信号强度指示大于预设阈值，基于所述采样报文中的采样IQ数据得到位置角度。通过将数据信号强度指示小于预设阈值的信号排除，可以滤除信号质量较差的信号，从而使得用于计算位置角度的信号质量较高，保证最终计算得到的位置角度的精确性。
