ELM327 Bluetooth Adapters are used to connect your vehicles computer (ECU) to a smartphone, tablet, laptop or desktop computer. The Bluetooth adapter transmits a signal from the ELM327 device to the receiving device over a wireless Bluetooth connect; meaning, the device you are receiving the data on needs to be Bluetooth enabled. Not all device are Bluetooth enabled by default but most smartphones and tablets will have the option to switch Bluetooth on and off. Laptops and computers are less likely to have Bluetooth and may require an external USB Bluetooth radio receiver to receive the signal.
Bluetooth Signal Reach
The ELM327 broadcasts a Bluetooth Signal that reaches 10 meters or approximately 32 feet. This signal can be reduced by walls or other interference. If you have a vehicle in a garage or outside and want to be able to diagnose it from in your house, workshop or place of business with a desktop computer, there is a possibility that the signal will be strong enough that you will be able to do this from at least a limited distance. Another option of increasing the range is to use an OBD-II extension cable.
