What is the difference between Bluetooth and Bluetooth Smart?
What is Bluetooth Low Energy (BLE)? Bluetooth Low Energy, also known as Bluetooth smart, is a variant of “classic” Bluetooth that allows you to send small amounts of data. The main difference between Bluetooth and Bluetooth Low Energy is the low power consumption of the latter. Hence its name “Low Energy“.
What is Bluetooth Low Energy scanning?
BLE scanning. An Android device can target and scan for specific Bluetooth devices more efficiently when using BLE. BLE APIs let app developers create filters for finding devices with less involvement from the host controller.
How do I connect my BLE device to my Android?
As far as I know, to initiate a pairing procedure in BLE there are two ways: 1) From API 19 and up you can start the pairing by calling the mBluetoothDevice. createBond() . You don’t need to be connected with the remote BLE device to start the pairing process.
What is the benefit of Bluetooth Smart?
Bluetooth 4.0—or Bluetooth Smart—gives the standard a brain transplant. The new specification uses improved technology that helps everyday gadgets stay paired longer while using less power.
How does Bluetooth Smart Work?
Bluetooth Smart devices send data back to Bluetooth Smart Ready devices for the data to be fed into an app or program, which is then displayed to the user. Bluetooth 4.0 requires very little power consumption, compared to previous versions, which enables more devices to take advantage of Bluetooth technology.
What does a Bluetooth sniffer do?
A sniffer is an incredibly powerful and valuable tool debugging your own hardware, reverse engineering existing BLE peripherals, or just to learn the ins and outs of how Bluetooth Low Energy actually works on the a packet by packet level.
How do I debug a Bluetooth device?
Enabling Bluetooth Debug on Android In Android, enabling the Bluetooth logging is as simple as going to Settings -> Developer Options and enabling “Enable Bluetooth HCI snoop log”. This will save the data in /sdcard/btsnoop_hci. log which can be copied and opened in Wireshark.
What is BLE Android?
Android provides built-in platform support for Bluetooth Low Energy (BLE) in the central role and provides APIs that apps can use to discover devices, query for services, and transmit information. Common use cases include the following: Transferring small amounts of data between nearby devices.
What is Companion device Manager used for?
On devices running Android 8.0 (API level 26) and higher, companion device pairing performs a Bluetooth or Wi-Fi scan of nearby devices on behalf of your app without requiring the ACCESS_FINE_LOCATION permission. This helps maximize user privacy protections.
What is a BLE connection?
BLE devices are able to connect with a larger number of other devices, or ‘slaves’, compared to standard bluetooth. BLE devices can vary in how many connections they are able to make with other devices depending on the memory built into them and how they are being implemented.

What is GATT service on Android?
The GATT profile is a general specification for sending and receiving short pieces of data known as “attributes” over a BLE link. All current BLE application profiles are based on GATT. Review the Android BluetoothLeGatt sample on GitHub to learn more. Profiles.
Why do we need BLE?
One of the major BLE benefits is that it can be used for accurate positioning where GPS can’t – indoors. You can use BLE-equipped devices as beacons, i.e., to broadcast data to all devices in the vicinity, rather than to have one-to-one exchange.
How does Bluetooth work on Android devices?
