What is BT 4.1 and 4.2~ That is a frequent question for our customers.

Here, we quoted some information from SIG to help readers have easy understanding between different Bluetooth version.

BT 4.1

This updated specification aims to improve consumer usability with increased co-existence support for LTE,  efficient data exchange rates, and aid developer innovation by allowing devices to support multiple roles simultaneously. 

• Improving Usability—extends the brand promise to consumers with an “it just works” experience. This spec is engineered with several new features to make it work seamlessly with popular cell technologies like LTE, maintain connections with less frequent manual reconnection, and deliver a more efficient data exchange.
• Empowering Developer Innovation—provides developers with greater flexibility to create innovative Bluetooth products and solutions through dual-mode topology and link-layer topology software features.
• Enabling the Internet of Things—lays the groundwork for IP-based connections by allowing devices to setup a dedicated communication channel in the future thereby extending the central position for Bluetooth technology in the Internet of Things.

BT 4.2

Key updates in 4.2 improve privacy and increase speed, and a soon-to-be ratified profile will enable IP connectivity.

• Privacy and Security

Bluetooth 4.2 introduces industry-leading privacy settings that lowers power consumption and builds upon the government-grade security features of the Bluetooth specification. The new privacy features put control back into the hands of the consumer by making it difficult for eavesdroppers to track a device through its Bluetooth connection without permission. For example, when shopping in a retail store with beacons, unless you’ve enabled permission for the beacon to engage with your device, you can’t be tracked.

• Speed

Bluetooth 4.2 increases the speed and reliability of data transfers between Bluetooth Smart devices. By increasing the capacity of Bluetooth Smart packets, devices transfer data up to 2.5 times faster than with previous versions. Increased data transfer speeds and packet capacity reduces the opportunity for transmission errors to occur and reduces battery consumption, resulting in a more efficient connection. 

• Internet Connectivity

Building on the capabilities released earlier with Bluetooth 4.1 and the new features released in 4.2, the Internet Protocol Support Profile (IPSP) will allow Bluetooth Smart sensors to access the Internet directly via IPv6/6LoWPAN. IP connectivity makes it possible to use existing IP infrastructure to manage Bluetooth Smart “edge” devices. This is ideal for connected home scenarios that need both personal and wide area control. This profile will be ratified by the end of the year.

Now both ‪#‎nRF51‬ & ‪#‎nRF52‬ Support IPv6 Over Bluetooth Smart.‪#‎nRF5SDK‬

Quoted from Nordic: http://www.nordicsemi.com/eng/Products/Bluetooth-Smart-Bluetooth-low-energy/nRF5-SDK-for-IoT

This SDK is a IPv6 capable Bluetooth® Smart software stack that provides drivers, libraries, examples, and APIs for nRF52 Series devices. It includes an IPv6 over Bluetooth Smart adaptation layer (6LoWPAN) and a complete Internet Protocol Suite including IPv6, ICMP, UDP, TCP, DTLS, TLS, CoAP and MQTT. It brings native IPv6 support to Bluetooth Smart applications, letting them talk directly to cloud services and other connected ‘things’ over IP-based networks.

The SDK includes examples that configure the nRF52 device as a Bluetooth Smart 6LoWPAN node and that interface with the IP layers at transport level (UDP amd TCP) and with security (DTLS and TLS), to the application level CoAP and MQTT and LWM2M. Examples of how to connect to cloud services is also included in the documentation. The SDK also includes an implementation to for over the air upgrade for Bluetooth Smart IPv6 nodes over IP using the trivial file transport protocol (TFTP).

As a router for development an off-the-shelf router running OpenWRT or a Raspberry Pi can be used. A solution for commissioning of Bluetooth Smart IPv6 nodes to a router with a mobile phone as a trusted third party is also included. Source code for the commissioning app and the needed OpenWRT daemon is also available. All this is described in the documentation.

The nRF5 IoT SDK documentation are available at our infocenter.

The nRF5 IoT SDK zip and pack version are available for download developer.nordicsemi.com.
