I am working on a lost and found application that will keep track of a person's belongings using Bluetooth. The application is supposed to work like Tile App and other similar apps.
Bluetooth enabled tags will be attached to items. When an item needs to be searched, Bluetooth from the smartphone will be used to search for the Bluetooth enabled tag.
When the smartphone goes out of the object's range, the tag will notify the person through sound and light alert.
Could you suggest which Bluetooth modules would work best for such an application? Thank you.
