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.

The nRF51824 is qualified to the automotive AEC-Q100 stress test qualification for integrated circuits and delivers the same flexible feature range and performance as Nordic’s highly successful nRF51822 SoC

Nordic Semiconductor today announces the immediate availability of the nRF51824 Bluetooth® low energy (formerly Bluetooth Smart) SoC for the latest connected car intelligent automotive applications and wireless in-car charging.

The nRF51824 is qualified to the automotive AEC-Q100 stress test qualification for integrated circuits, and delivers the same flexible feature range and performance as Nordic’s highly successful and field-proven nRF51822 Bluetooth low energy SoC (256kB Flash and 16kB RAM variant) upon which the nRF51824 is based.

“The world of automotive is evolving rapidly towards the emergence of the connected car, and connected in-car ecosystems” says John Leonard, Product Marketing Manager at Nordic Semiconductor. “This will expand from Bluetooth enabled smartphones and tablets being wirelessly linked to in-car user interfaces to having a vast array of other factory-fitted elements being made wirelessly controllable and configurable.

“This will lead to connected in-vehicle ecosystems that contain ‘swarms of wireless sensors’ for driving experience enhancement, safety, and diagnostics. Examples will include intelligent seats, intelligent steering wheels, remote keyless entry [RKE] systems, intelligent mirrors, infotainment systems, and intelligent accident or incident proximity reporting. It also brings exciting opportunities for after-market equipment suppliers to deliver innovative in-car systems that communicate with each other and with smart mobile devices. The nRF51824 is the world’s most powerful automotive qualified Bluetooth low energy SoC and as such is very well suited to these application demands”

Under-the-hood systems could also benefit from Bluetooth wireless functionality, because this would enable manufacturers to reduce the cost and weight of traditional cable looms to offer simpler factory assembly, maintenance, and replacement, plus increased fuel economy.
