Abstract: A method for establishing synchronization relationship, a chip, an electronic device, and a non-transitory computer-readable storage medium are provided. The method includes the following. A synchronization pulse of the master device is initiated according to a pulse period preset. A start time of a K1th synchronization pulse and a start time of a K2th connection event of a slave device are obtained, and an offset time is obtained according to the start time of the K1th synchronization pulse and the start time of the K2th connection event. First synchronization information is transmitted to the slave device for the slave device to start a local synchronization pulse synchronized with the synchronization pulse of the master device according to the first synchronization information. The first synchronization information carries a count value K1, a count value K2, the offset time, and the pulse period.

Abstract: Provided are a topology switching method based on isochronous channel, an apparatus, a system and a storage medium. The method is applied to a first central slave device. There are a plurality of first isochronous channels between the first central slave device and a master device, and there is a first communication channel between the first central slave device and a peripheral slave device. The method includes: sending, by first central slave device, first isochronization information to peripheral slave device through the first communication channel, where the first isochronization information includes a channel parameter of first isochronous channel, so that peripheral slave device starts data transmission with master device according to the channel parameter of first isochronous channel; and stopping, by first central slave device, data transmission with master device through the first isochronous channel, before peripheral slave device starts data transmission with master device.
