Step 2

Remove byte stuffing.

To remove byte stuffing, check for instances of “7D 5D” or “7D 5E” and replace as follows:

7D 5D

=> 7D

7D 5E

=> 7E

Step 3

Confirm FCS.

Calculate the checksum for the HDLC payload.

Confirm that the FCS matches the FCS sent with the packet. Because the packet encodes FCS least significant byte
first, in this example the calculated FCS should match “E8 40”.

Step 4

(Application layer) parse HDLC payload content.

The resulting packet payload is as follows.

As described in section 7.4.3.6, an 0x8A command with parameter type 0x07 has the following message content

structure.

Therefore, this is a mote information response with no errors (and a payload length of 32 bytes). The mote
information is as follows (actual values will vary, see section 7.4.4.7).
