This week the Bluetooth Special Interest Group (SIG) announced that it adopted a new version of the Bluetooth core specification. The newest Bluetooth 4.2 update comes a year after 4.1 was adopted, which laid the groundwork for better Internet of Things (IoT) functionality, less LTE interference, improved data transfers and device reconnection. However, Bluetooth 4.2 adds more user-friendly features, such as increased speed, privacy and Internet connectivity.
