Table 2. UDP Packet

Parameter Description
Setup and scenario info Device wakes up from hibernate every 5 seconds, and transmits 1 packet on UDP socket.
The AP connection security is open.
Average current consumption (steady-state) 0.98 mA
Electric charge consumption of one active cycle 3.8 mC

Figure 11 and Figure 12 describe the use case profile.

Table 3. TCP Packet

Parameter Description
Setup and scenario info The AP connection security is open.
Device wakes up from hibernate every 5 seconds. Establishes a TCP and SSL connection, and then transmit 1 TCP secured packet. The SSL version is SSLv3, and the cipher is "RSA_WITH_RC4_128_SHA".
Average current consumption (steady-state) 2.4 mA
Electric charge consumption of one active cycle 13.3 mC
Remarks This examples requires a peer server.
For more information on how to setup a server with Python scripts, see the Appendix section.

Figure 13 and Figure 14 describe the use case profile.
