MAC Address Rotation Test Cases

This section covers test cases for verifying BLE MAC address rotation behavior on Sidewalk Endpoints. MAC address rotation is a privacy mechanism that ensures the BLE beacon MAC address changes on specific events and at regular intervals.

Test Case BLE/EP/BCN/MAC/BV/01: Verify MAC address rotation after registration

Field	Value
Case ID	C103619309
Executable by Customer	Yes

Preconditions

BT sniffer is ready to capture BLE beacons

Test Steps

Step	Description	Expected Result
1	Initialize BLE stack and collect MAC address in beacon: `sid init 1` `sid start`	`CMD: ERR: 0` BT sniffer captures BLE beacon with MAC address: `<mac_addr_1>`
2	Wait for EN to register and collect MAC address again	`EVENT SID STATUS: State: 0, Reg: 0, Time: 0, Link_Mask: 1` BT sniffer captures BLE beacon with MAC address: `<mac_addr_2>`
3	Check MAC address rotation	`mac_addr_1 != mac_addr_2`

Key check: MAC address rotated after registration (Reg: 0 confirms registered state)

Preconditions

BT sniffer is ready to capture BLE beacons

Test Steps

Step	Description	Expected Result
1	Initialize BLE stack and collect MAC address before time sync: `sid init 1` `sid start`	`CMD: ERR: 0` `EVENT SID STATUS: State: 0, Reg: 0, Time: 1, Link_Mask: 1` BT sniffer captures BLE beacon with MAC address: `<mac_addr_1>` Key check: EN registered (Reg: 0), time not yet synced (Time: 1)

Field	Value
Case ID	C103619311
Executable by Customer	Yes

Preconditions

BT sniffer is ready to capture BLE beacons

Test Steps

Step	Description	Expected Result
1	Initialize BLE stack, wait for time sync, wait another 30s to confirm BLE disconnected: `sid init 1` `sid start`	`CMD: ERR: 0` `EVENT SID STATUS: State: 0, Reg: 0, Time: 0, Link_Mask: 0` `EVENT SID STATUS LINK MODE: LORA: 0, FSK: 0, BLE: 0` Key check: Time synced (Time: 0), BLE disconnected
2	Monitor 2 MAC address rotations (check every 30s, expect rotation ~15 min)	Round 1: MAC rotated after ~900s (`<mac_addr_1>` -> `<mac_addr_2>`) Round 2: MAC rotated after ~900s (`<mac_addr_2>` -> `<mac_addr_3>`)
3	Check MAC address rotation interval	All 3 MAC addresses are unique

Key check: Each rotation interval is between 840s~960s (14~16 min). MAC rotates every ~15 minutes.
