Bluetooth is an open and short-distance wireless communication technology standard. It is used to achieve wireless network interconnection between fixed devices and mobile devices in a small range [1].

Because of the functional requirements of the project, you need to port the bluez Bluetooth protocol stack to the S3C2410 development platform. Many problems occur during the transplantation process, such as the version mismatch of the dependent library, the cross-compiler version is too high or too low. In order to reduce the migration detours, We will summarize the combined version and compilation process we tested in our own hands as follows, at th

2. Bluetooth Network Communication Process
1) when a bluetooth device is not connected, it is in sleep mode-standby mode ). In this mode, it wakes up every 1.28s or 2.56s and selects a channel to listen for the information sent to it.
2) A device initiates a connection, and the device will become the main unit of the net

2) connectable directed event type (connectable)
3) scannable undirected event type (no targeted broadcast can be scanned)
