Dispositivo Comunicacao Bluetooth BLE BEACON

Smart Beacon Two, a new generation of the Smart Beacon with double the battery life. Better yet, since we have much larger battery capacity in the Smart Beacon Two, we’ll soon be adding the capacity to broadcast Eddystone and iBeacon formats at the same time, which is a feature that we know a lot of you have been asking for.

A beacon is a small Bluetooth radio transmitter.

It’s kind of like a lighthouse: it repeatedly transmits a single signal that other devices can see. Instead of emitting visible light, though, it broadcasts a radio signal that is made up of a combination of letters and numbers transmitted on a regular interval of approximately 1/10th of a second. A Bluetooth-equipped device like a smartphone can see” a beacon once it’s in range, much like sailors looking for a lighthouse to know where they are.

But what is a beacon like on the inside?

What do they look like? Beacons are very small, simple devices. If you crack one open, you won’t find thirty motherboards and oodles of wires. You’ll find a CPU, radio, and batteries. Beacons often use small lithium chip batteries (smaller and more powerful than AA batteries) or run via connected power like USB plugs. They come in different shapes and colors, may include accelerometers, temperature sensors, or unique add-ons but all of them have one thing in common—they transmit a signal.
What is a beacon actually transmitting?

It’s not throwing just any old message into the air. It’s transmitting a unique ID number that tells a listening device which beacon it’s next to.
Really, it’s just a code name.


How can I interact with beacons?

For example, when a shopping mall installs beacons in their shop, all of the beacons will have certain IDs, registered in their dedicated app. This means a smartphone app can immediately recognize that the incoming ID is important and that it’s from that particular mall. The ID, however, has little meaning on its own; it’s entirely up to an app or other program to recognize what it means.

What happens next? That depends on what the owner has programmed it to do. One code could trigger the app to send a coupon. Another could offer navigation services. The possibilities are nearly endless. All the beacon has to do is connect your exact location to the app, and the rest is up to the program.
