Abstract: An interference detection method and apparatus, a storage medium, and a terminal are provided. The method includes: receiving a signal; obtaining a power value of the signal as a first power; filtering the signal to obtain a filtered signal; obtaining a power value of the filtered signal as a second power; and determining whether a frequency channel where the signal is located is an interference frequency channel or a non-interference frequency channel based on a comparison result of a ratio of the first power to the second power and a preset threshold.

Abstract: A communication method, a communication device, and a readable storage medium, wherein the communication method includes: establishing a communication connection with a data source device; establishing a second wired connection with at least one other device; and exchanging identification information with the at least one other device through the second wired connection, thereby the at least one other device receiving communication data sent from the data source device according to the received identification information. With the above method, multi-device communication is performed quickly and reliably.

Abstract: A method and an apparatus for Bluetooth connection are disclosed. A first Bluetooth connection can be established between a first node of multiple data receiving nodes and a data source, the multiple data receiving nodes can share a data packet transmitted by the data source via the first Bluetooth connection, and a second node can be selected according to a preset rule from among the multiple data receiving nodes to feed back a response signal to the data source. In a method and an apparatus, the multiple data receiving nodes can be regarded as a whole, which share a data packet transmitted from the data source and jointly maintain the first Bluetooth connection, and only one of the multiple data receiving nodes is selected to feed back a response signal. Conforming to Bluetooth communication protocols, a method and an apparatus can meet the demanding requirements on hardware resources of a Bluetooth connection among a data source and multiple data receiving nodes.
