Bluetooth chip definition: Bluetooth chip is an integrated Bluetooth functionCircuitCollection is used for short -range wireless communication. Its application scenarios include audio transmission, data transmission, location services, and equipment networks.

Bluetooth chip classification: According to Bluetooth transmission standards, Bluetooth chip can be divided into classic Bluetooth chips and BLE (low power Bluetooth).

① The classic Bluetooth chip uses the SBC encoding format, which is often used to transmit audio, files and other scenarios, with high power consumption.

② The BLE chip uses the LC3 encoding format, which is often used in scenes such as device matching, data synchronization, positioning, etc., which has the advantages of low power consumption and low latency.

This is a domestic Bluetooth chip from Gongcai.com. It is widely used in Bluetooth K Gingbao, Bluetooth portable speakers, Bluetooth trailer, Bluetooth Soundbar, automatic follow -up bags, Baotou Bluetooth headsets, various Bluetooth audio and voice application productsFields.
