GAP and GATT adaptation protocol over internet protocol
In a second group of embodiments, an electronic device that provides a virtual Bluetooth gateway is described. During operation, the electronic device may receive a first packet associated with a second electronic device and that has an Internet Protocol (IP)-compatible format (such as a JavaScript Object Notation or JSON format). Then, the electronic device may de-encapsulate a second packet from the first packet, where the second packet is compatible with a Bluetooth communication protocol. Next, the electronic may provide the second packet. Note that the electronic device may not include a physical Bluetooth radio, such as dedicated hardware for a physical Bluetooth radio. Instead, the electronic device may include a virtual Bluetooth device that communicates with the second electronic device via the virtual Bluetooth gateway. This virtual Bluetooth device may have the capabilities of a physical Bluetooth radio (without the dedicated hardware).
