What is Whisper Mode Pairing?

Whisper Mode Pairing is a feature of the BL600 firmware, since version 1.5.66.0. It is a completely unique approach that further enhances security and ease during the pairing process. In Whisper Mode, transmission power is automatically decreased when pairing is detected to be in progress; thus a proximity based enhanced security is achieved. This behavior ensures that pairing is not completed unless devices are within a relatively close proximity to each other. With Whisper Mode, end users who are implementing Laird’s BL600 into their products can be certain they are connecting to the correct, intended remote device by simply bringing them into close proximity.
