5.4.6 Key Establishment Process
To complete security authentication, use AT+CBKESTART and AT+CBKEPARTNER command.
 Use AT+CBKESTART for Trust Center(coordinator)↔end-device Key Establishment.
 Use AT+CBKEPARTNER for Partner Key Exchange between nodes other than Trust Center.
Example) Initiate Key Establishment from ProBeeSEID(end-device) to ProBeeSESI(coordinator)
#Screen of ProBeeSEID(end-device)
AT+DEST=0000,01 # Set destination node to coordinator(0x0000),
# End-point is 0x01
DESTINATION ADDRESS: 0x0000, END POINT: 0x01
OK
AT+CBKESTART
CBKE DEST: 0x0000, EP: 0x01, RESULT: 0x00
OK
+0000|SE_INIT_CBKE_RESPONSE
+0000|SE_EPHEMERAL_DATA_RESPONSE
+0000|SE_CONFIRM_KEY_DATA_RESPONSE
Then ProBeeSESI(coordinator) node receives following messages:
#Screen of ProBeeSESI(coordinator)
+CEDF|SE_INIT_CBKE_REQUEST # +CEDF is short address of end-device,
+CEDF|SE_EPHEMERAL_DATA_REQUEST # it can be shown differently
+CEDF|SE_CONFIRM_KEY_DATA_REQUEST # in your screen
+CEDF|SE_GLOBAL_COMMAND|0800|0B
Key Table of ProBeeSESI is changed as follows:
#Screen of ProBeeSESI(coordinator)
AT+KEYTABLE
NETWORK KEY: FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
