BLUETOOTH SCANNER FOR ANDROID ANDROID
In case, if we want to discover the available Bluetooth devices or manipulate Bluetooth settings from our app, we need to define BLUETOOTH_ADMIN permission.įollowing is the example of defining the Bluetooth permissions in android manifest file. We need this permission because the Bluetooth scans can be used to gather the information about the location of user. We need this permission to perform any Bluetooth communication, such as requesting a connection, accepting a connection, and transferring data. To use Bluetooth features in our android applications, we must need to add multiple permissions, such as BLUETOOTH and ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION in our manifest file. The two devices remain bonded, so they can reconnect automatically during a future session as long as they're in the range of each other. When the session is complete, the device that initiated the pairing request will release the channel that linked to the discoverable device. Once the pairing and bonding process completes, the devices are ready to exchange the required information. Once the device accepts the pairing request, the two devices will exchange security keys to complete the bonding process and the devices will cache these security keys for later use. Generally, the devices will find discoverable devices using a service discovery process. The devices which we are going to pair must be discoverable and should accept the incoming connection requests. To transfer the data between two Bluetooth devices first, they must establish a communication channel using the pairing process. Transfer data to and from other devices.Connect to other devices through service discovery.Use local Bluetooth adapter for paired Bluetooth devices.Scan for the available Bluetooth devices within the range.Generally, in android applications by using Bluetooth API’s we can implement Bluetooth functionalities, such as searching for the available Bluetooth devices, connecting with the devices and managing the data transfer between devices within the range.īy using android Bluetooth API’s in android applications, we can perform the following functionalities. LX offers unparalleled performance, delivering up to 4 times as many samples per second as the closest competitor. In android, Bluetooth is a communication network protocol, which allows devices to connect wirelessly to exchange the data with other Bluetooth devices. OBDLink ® LX is a Bluetooth OBD-II adapter that can turn your smart phone, tablet, or laptop into a sophisticated diagnostic scan tool, trip computer, and real-time performance monitor.
