DPA Peer-to-Peer (DP2P from now) allows communicating with bonded [Ns] at the existing network in non-network mode. Unlike DSM no reset or restart of the [N] is needed. DP2P is useful for inventorying the network (e.g. localization of the [Ns] after autonetwork), device maintenance, remote control, etc. Communication runs on the network A channel and the data is encrypted by an AES-128 algorithm using an access password as a key. DP2P must be enabled in the [N] configuration to work. All packets use the _DPAF flag and DPA reserves the right to use this flag exclusively only for DP2P purposes in case of non-networking packets.
The DP2P protocol consists of one DP2P Request packet (it contains DPA Request that is executed at the addressed [Ns]) and then DP2P Response Handshake packets exchanged between the addressed and reachable [Ns] and the device, that sent DP2P Request.
