Abstract
A Bluetooth ranging correction method and apparatus, an initiator, and a medium are disclosed. The method comprises: sending by an initiator a first continuous wave signal to a reflector; performing by the reflector frequency conversion on the first continuous wave signal to obtain a first measurement; switching by the initiator to a reception state, and obtaining a first timestamp; receiving by the initiator a second continuous wave signal from the reflector, obtaining a second timestamp and performing by the initiator frequency conversion on the second continuous wave signal to obtain a second measurement; and obtaining by the initiator the first measurement from the reflector, performing correction on the first and second measurements using the first and second timestamps and determining a distance between the initiator and the reflector by using the corrected first and second measurement values. The method can correct the distance measurement, reducing measurement deviation during Bluetooth ranging.
