Bluetooth, is a support equipment short distance communication (general 10m) radio technology, after recent years of development, we are no longer unfamiliar with it, it is also the current digital products indispensable modules. The advent of Bluetooth technology allows us to connect a variety of devices are no longer bound by a wide range of data lines, such as audio, computers, mice, keyboards, and even

created, using Gatt.connect (); Re-establish the connection.* But in this case the result of the test is that reconnecting takes a long time.* The solution is through GATT = Device.connectgatt (this, false, Gattcallback); A new Connection object is established, which is obviously much faster than the previous method.* However, the direct result of multiple creation of the GATT connection object is that more than 6 GATT has been created and will no longer be connected to any devices, since the n

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
