SA (Secure Access)

The Secure Access Options bit-field defines the feature set(s) intended to be secure against unauthorized access. The XBee 3 802.15.4 RF Module should establish a secure session in order to 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)

Bit field

Unused bits must be set to 0. These bits may be logically OR'ed together:

Bit	Description
0	Reserved
1	Remote AT Commands When set to 1 and if a password has been set, the device will not respond to insecure Remote AT Command requests (API Frame 0x17) but still can send insecure Remote AT Commands.
2	Serial Data When set to 1, the device will not emit any serial data that was sent insecurely. This functionality applies to devices that are configured for Transparent mode, but in this instance, only the SRP server would be AP = 0, the client would still have to send the Secure Session Control - 0x2E via API mode. The server will also not emit any 0x90 or 0x91 frames when this bit is set. Note On 802.15.4 insecure 0x80 frames will also not be emitted.

Default

0
