Abstract
Systems, devices, and methods synchronize sensor data and timestamps based on a second clock of a second device relative to a first clock of a first device. The data are communicated from the second device to the first device by way of respective wireless circuits in the first and second devices. Timestamps based on the second clock are corrected based on one or more of a time offset value and a clock frequency offset value of the second clock relative to the first clock. The timestamps for the sensor data are scaled to account for clock drift, and shifted to account for clock offset error.
