An Overview Of Bluetooth Beacons Part 2 Novel Bits Bluetooth beacons are small wireless, usually battery powered devices that transmit data at regular intervals using bluetooth low energy (ble). this mini radio transmission device can be ‘discovered’ and seen by all ble scanners within a certain radius. the bluetooth beacon, however, cannot ‘see’ anyone back. An overview of bluetooth beacons – part 2 #bluetooth #internetofthings #iot @novelbits mohammad afaneh on novelbits continues a series of posts on bluetooth beacons, focusing on use of beacons. bluetooth beacons are small and wireless battery powered radio transmitters that use ble as their transmission protocol.
An Overview Of Bluetooth Beacons Part 2 Novel Bits Step #2: define the advertising data. for this, we’ll define a data structure to define the advertising data and then we’ll instantiate two variables, one for holding the uid data and the other for the tlm data. both types will include the following fields: flags. length field (1 byte) = 0x02. These parameters are: advertising interval: this value ranges from 20 ms – 10.24 seconds (in 0.625 ms increment values (meaning that the valid values are 20 ms, 20.625 ms, 21.25 ms, etc.). advertising channels used: a device can only advertise on a subset of the three primary advertising channels. Cost: the technology enables 60 80% cheaper cost of operation than competing standards. power consumption: 50 99% less power used means the average beacon can last up to 2 years (or even 5 years with our beacons) application: bluetooth le technology is perfect for beacons since applications only require minimal periodic transfers of data. as. Bluetooth ® beacons, of course, are hardly standing still. the recent release of bluetooth 5 will have many very real (and very big) results for beacon users. bluetooth 5 brings three big changes and each of these will have very specific results for beacons. bluetooth 5 means: 4x the range. 800% more broadcast messaging capacity. 2x the speed.
