You will get the accept callback which at than you can get access to bt_gatt_client, for disconnection the idea is that you register a callback directly to bt_att but perhaps we need some other mechanism. Anyway we first need to move to bt_hog instead. > Or how do I get current db and client handles that I can use for all operations? That sound strange, you just have done this for device_info and you don't know it? From the accept callback you get the device and with that you can access the db that should contain all the details, anyway we should probably change bt_hog to use bt_gatt_client and gatt_db internally so we can share with android code. -- Luiz Augusto von Dentz -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
