8.4 Data Transmission

GPD transmits the data packet to the sink device via proxy, if the proxy device is present in the network. In such cases, the proxy device sends the GP notification on behalf of the GPD device. The following figure illustrates the data transmission from the GPD via proxy.
Figure 8-4. Data Transmission from GPD via Proxy
If the proxy device is not present in the network, the GPD sends the data to the sink device. The following figure illustrates the GPD data TX without proxy.
