# sudo bluetoothctl

[bluetoothctl]# power on

[bluetooth]# discoverable on

As of Bluetooth v2.1, SPP offers three methods of pairing devices, which are applicable on the Edge Gateway:

● Just Works

● Numeric Comparison

● Passkey Entry

NOTE: For more information about Bluetooth pairing, see blog.bluetooth.com/bluetooth-pairing-part-4.
