With the development of Internet of Things, numerous IoT devices have been brought into our daily lives. Bluetooth Low Energy (BLE), due to the low energy consumption and generic service stack, has become one of the most popular wireless communication technologies for IoT. However, because of the short communication range and exclusive connection pattern, a BLE-equipped device can only be used by a single user near the device. To fully explore the benefits of BLE and make BLE-equipped devices truly accessible over the Internet as IoT devices, in this paper, we propose a cloud-based software framework that can enable multiple users to interact with various BLE IoT devices over the Internet. This framework includes an agent program, a suite of services hosting in cloud, and a set of RESTful APIs exposed to Internet users. Given the availability of this framework, the access to BLE devices can be extended from local to the Internet scale without any software or hardware changes to BLE devices, and more importantly, shared usage of remote BLE devices over the Internet is also made available.
