How Does Bluetooth Calling Work on a Smartwatch?
Bluetooth calling on a smartwatch involves pairing the device with a smartphone via Bluetooth, allowing the watch to receive call notifications. The smartphone handles the actual call using its cellular connection, while the watch provides a control interface. Calls can be answered or initiated through the watch, using its built-in speakers and microphone or a connected Bluetooth headset. The process relies on Bluetooth profiles like HFP or HSP for voice and control signals.
