Examples of Applications/Examples of Utilization Technologies
Applications using the Bluetooth® low energy technology have started to be used widely in healthcare devices, and the use of the Bluetooth low energy technology is still expanding in a wide variety of applications for sports and fitness devices, smart home devices, industrial devices, beacon applications, etc.
Beacons are applications which continue to transmit ID/URL/vendor information for advertisement notification to smartphones and location detection through smartphones. As beacons must always continue to transmit radio waves, the most important thing is to operate them with low power consumption. Renesas offers stack exclusively for beacons, specialized in lower power consumption.
