-:example:`bluetooth/bluedroid/classic_bt/bt_spp_acceptor` demonstrates how to use Bluetooth capabilities to create a Serial Port Protocol (SPP) acceptor that acts as a server and integrate Secure Simple Pairing (SSP). This example also includes a demo for communicating with an SPP initiator that acts as a client.
