Connecting BLE devices to the cloud

The internet protocol (IP) is the basis of the internet as we know it; it contains addressing and routing across network boundaries, and you can run application protocols such as MQTT or CoAP right on top of it. For a device to work with IP directly, it uses a radio such as cellular, Wi-Fi or Thread. However, IP also comes with some downsides. Its memory overhead doesn’t always make it the best choice for constrained devices. Also, because addressing is part of the protocol, packet sizes are relatively big, which means the radio takes more time to transmit. This has a negative effect on power consumption. Thus, not all small IoT devices support IP but instead support protocols such as Bluetooth Low Energy (BLE) and LoRaWAN, which are cheap and energy-efficient but do not allow direct access to the internet.
