Abstract
In a communication system comprising one master device and one or more slave devices, the slave devices synchronize to a common timebase maintained at the master device, independently of a wireless module timebase, without requiring transmission of accurate and real time master timer information from the master device. In one approach, a slave device sends timing information to the master device, the timing information representing the slave device timebase, and the master device sends back correction information to the slave device, the correction information representing a difference between the slave device timebase and the master device timebase, the correction information being usable independent of the timing of sending back the correction information. The master timebase might be a system master timer of an accurate timer based on a timer interrupt and a high resolution timer having a resolution greater than a timer interrupt resolution.
