$S (SRP Salt)

Note You should only use this command if you have already configured a password on the XBee device and the salt corresponds to the password.

The SRP (Secure Remote Password) Salt is a 32-bit number used to create an encrypted password for the XBee device. The $S command is used in conjunction with the $V, $W, $X, and $Y verifiers. Together, the command and the verifiers authenticate the client for the BLE API Service without storing the XBee password on the XBee device.

The salt is configured in the $S command. In the $V, $W, $X, and $Y verifiers, you specify the 128-byte verifier value, where each command represents 32 bytes of the total 128-byte verifier value.

Note XBee device does not allow for 0 to be valid salt. If the value is 0, SRP is disabled and you will not be able to authenticate using Bluetooth.
