Secure Session commands

These are the AT commands that enable Secure Session.

*S (Secure Session Salt)

The Secure Remote Password (SRP) Salt is a 32-bit number used to create an encrypted password for
the XBee 3 Zigbee RF Module. The *S command contains the salt value in the salt/verifier pair used for
secure session authentication.
Parameter range

0

*V, *W, *X, *Y (Secure Session Verifier)

The secure session verifier is a 128-byte value used together with
session authentication. The *V, *W, *X, and *Y commands each contain 32 bytes of the secure session
verifier: *V contains bytes 0 - 31, *W bytes 32 - 63, *X bytes 54 - 95, and *Y bytes 96 - 127.
Parameter range
Each command can be any 32-byte value: 0-FFFFFFFF

access functionality defined by the feature set(s) on the local device.
A password must be set using the Secure Session Salt and Verifier before access is secured.
Parameter range
0 - 0x1F (up to 0xFFFF)
