GATT service discovery procedure for two or more devices

A circuitry of an electronic device, configured to perform the steps of:

• wirelessly connecting to a first device;
• performing a service discovery to the first device to retrieve a plurality of attribute handles from the first device;
• storing the plurality of attribute handles of the first device into a database cache;
• wirelessly connecting to a second device;
• determining whether the second device and the first device have the same attribute handles;
• and
• in response to the second device having the same attribute handles as the first device, directly using the plurality of attribute handles of the first device stored in the database cache, without performing the service discovery to the second device, for using services of the second device;
• wherein the electronic device is a Bluetooth client, and both the first device and the second device are Bluetooth servers.

An electronic device, comprising:

• a wireless network module;
• and
• a storage device;
• wherein the wireless network module wirelessly connects to a first device, performs a service discovery to the first device to retrieve a plurality of attribute handles from the first device, and stores the plurality of attribute handles of the first device into the storage device;
• and the wireless network module wirelessly connects to a second device, and determines whether the second device and the first device have the same attribute handles;
• and in response to the second device having the same attribute handles as the first device, the wireless network module directly uses the plurality of attribute handles of the first device stored in the storage device, without performing the service discovery to the second device, for using services of the second device;
• wherein the electronic device is a Bluetooth client, and both the first device and the second device are Bluetooth servers.
