Determining at a bluetooth node the IP address of a peer bluetooth node

摘要

A method of determining at a Bluetooth node, the IP address of a peer Bluetooth node. The method comprises the steps of constructing an echo request message at the Layer 2 Control and Adaptation Protocol (L2CAP) layer of the first mentioned node, the message including in a payload field thereof an IP address query indicator. The echo request message is sent from the first mentioned node to the peer node. At the L2CAP layer of the peer node, an L2CAP echo response message is constructed, the echo response message including in a payload field thereof the IP address of the peer node. The echo response message is sent from the peer node to the first mentioned node and is decapsulated at the L2CAP layer of the first mentioned node to determine the IP address of the peer node.
