Bluetooth Version 4.1

- Apr 10, 2017-

Bluetooth Technology Alliance in December 2013 formally announced the use of Bluetooth core specifications 4.1 version. This specification is a software update to the Bluetooth 4.2 version, not a hardware update. This update includes the Bluetooth Core specification appendix (CSA1, 2, 3, and 4) and adds new functionality to increase consumer usability. These features include enhanced support for the coexistence of LTE and bulk data interchange rates, as well as enabling developers to innovate by allowing devices to support multiple roles simultaneously.
