Bluetooth advertising can also be received via laptop or PDA. Bluetooth advertising is permission based advertising, which means that when a mobile device has received a Bluetooth message, the recipient has the choice to either accept or decline the message. The recipient needs to positively indicate that they wish to receive marketing messages.
