XRange2000 is a long range Bluetooth transmitter that can be used for Bluetooth communications or Bluetooth advertising. It covers a very long range when compared to normal cheap Bluetooth dongles currently available in the market. Unfortunately, the cheap dongles are claimed to cover a 100-meter radius, but they actually do not cover a fraction of that. The XRange2000 can cover a very long range and it's compatible with BlueMagnet if you're looking to use it for Bluetooth advertising.
