wireless technology is a wireless communication link that works over the 2.4 GHz ISM band without requesting a license through a frequency hopping transceiver. It supports real-time AV and data communication between Bluetooth hosts. The link protocol is based on the timeslot.Bluetooth BasebandThis is the part of a Bluetooth system that specifies or implements a media access and physical layer program to su
Bluetooth is implemented on the HCI Layer regardless of the underlying hardware driver. That is to say, the driver of HCI on the host is mainly to provide unified interfaces for the upper layer, so that the upper layer protocol does not depend on the specific hardware implementation. The firmware of HCI in the hardware communicates with the driver of HCI on the host, such as UART, USB, and SDIO. The HCI Layer is abstracted as an hci_dev struct in fron
