While trying to understand how BT devices work I came across another related term "BT Beacon". Is it same as BT communication or if a device is termed as BT beacon then it would have some specific feature added or reduced in it from the vanilla BT devices?

Edit:

Some references about BT and Beacons:

  1. BT Wiki

  2. Beacon Wiki

  3. BLE Made Simple

  • \$\begingroup\$ where did you come across that term? Context helps! Might be just some Bluetooth LE advertisement, might be something else. \$\endgroup\$ – Marcus Müller Apr 27 at 21:28

    \$\begingroup\$ As explained at your previous question on this topic, bluetooth isn't really a great fit for your needs. It's going to be a challenge to find a solution that fits your form factor that does not require mounting chip-scale packages yourself. You were also already pointed to something that comes within a millimeter of meeting your goal. \$\endgroup\$ – Chris Stratton Apr 27 at 21:46

BLE beacons only send advertising messages, however they can not be paired to. An advertising message can contain a small amount of data. So, a beacon broadcasts this data for any receiver. (For example, a beacon may be broadcasting its own location in the advertising message. If I receive that advertising message, then I know that I'm near that location.)

BLE beacons have the identical communications hardware and software stack, compared to other BLE devices. They are configured to only send advertisement packages.

  • \$\begingroup\$ Let us say I have 2 Arduino boards which are communicating with each other over UART port. Now if I want to replace the UART Rx, Tx wires with BT modules then what should I use BT, BLE or Beacons? \$\endgroup\$ – ajeebx Apr 28 at 6:20
  • \$\begingroup\$ BT, BLE or Beacons it looks like all 3 can be used.. only price difference. \$\endgroup\$ – ajeebx Apr 29 at 7:58

    \$\begingroup\$ Do yourself a service: find some Bluetooth documentation with some depth, and read it. \$\endgroup\$ – Nick Alexeev Apr 29 at 15:13
