BLE Pairing and Bonding¶. Edited by: Laura Nao. Key concepts¶. Pairing: process where devices exchange the information necessary to establish an encrypted connection.It involves authenticating the identity of the two devices to be paired, encrypting the link, and distributing keys to allow security to be restarted on a reconnection.

 
I am trying to implement the following scenario: using a PSoC 4 BLE peripheral I updated the privacy example and I am trying to use it in my project. I start the peripheral using a public address; then I connect with an android smartphone to the device, pair it using a fixed passkey, bond the device and afterwards the phone disconnects.
Is there any way to establish a BLE connection initialized by a previously bonded Peripheral without using some application? Or tell the Android to reconnect automatically just with Android tools.
Sep 17, 2020 · In the BLESA process, two previously paired Bluetooth devices reconnect and involves both devices checking each other’s cryptographic keys to reconnect. As per the research now, the standard in the software means the checking part isn’t compulsory.

To read Bluetooth low energy characteristics after scanning, we first need to connect to a BLE device using connectToDevice method as shown above. Then further a connection needs to be established with a Gatt profile using device.connectGatt method, returning connection callbacks to the BluetoothGattCallback class also as shown in the example above.
