Find My Network TCKM002 Test Case Error

When TCKM002 is tested in the Key Management Test case, the iPhone will send a reset command to the accessory after selecting "Set+Verify key Rotations" in the FMCA app, resulting in the BLE disconnection. Sometimes iPhone will not send a Connection Indication Packet after disconnection. FMCA APP displays an error like attachment. May I ask why?
