You are helping a user pair a new Bluetooth headset with an Android smartphone for the first time. Which of the following must be true for the smartphone to discover the headset during the initial pairing process?
Both the phone and the headset are simultaneously set to discoverable mode.
Bluetooth is temporarily disabled on the smartphone to free radio channels for the headset.
The smartphone already has the headset's MAC address saved before scanning begins.
The headset is in discoverable (pairing) mode while the phone scans for devices.
During initial discovery, only the device that is being found (the headset) must be placed in discoverable or "pairing" mode. The phone simply scans for nearby discoverable devices. Making both devices discoverable is unnecessary, disabling Bluetooth on the phone would prevent discovery altogether, and knowing the headset's MAC address in advance is not required for standard pairing.
