ADP layer data exchange

To be able to execute an ADP command, the Node 1 and 2 working modes need to be set to

the ADP mode, as explained in Figure 18 on page 30.

To be able to send data at the ADP level, the macPANId and macShortAddress attributes

need to be configured for both nodes as in the MAC layer scenario (Section 10.4 on page

45).

The 6LoWPAN layer uses data encryption by default; so the MAC layer of the two nodes

needs to be configured with the same security keys.

In this scenario, the following key is used: [AF4D6DCCF14DE7C1C4235E6FEF6C151F],

as show in Figure 40. To configure it, go into the MAC / MLME_IB menu (1). In the list of

attributes for the set command, select the attribute macKeyTable (2). Then, enter the

security key in the Text area (3), leave the Index set to 0 and click on the MLME-

SET.Request button (4).

Figure 41. Configure Node 1 GMK

The same sequence needs to be repeated for the Node 2.

Once the security key has been configured for both nodes, data can be sent at the ADP

layer. The ADPD-DATA.Request command is available in the ADP root panel. No

destination PANId/macShortAddress needs to be entered at the ADP level, as the message

is an IPv6 packet that already contains the source and destination addresses. The IPv6

packet must be correctly formatted to perform the data exchange.

As a reference, the following is a working configuration for this test scenario, shown in

Figure 41:
