Abstract
(EN)
An example method of operating a device includes using a switching circuitry to a first subset of antennas from an antenna cluster, using the first subset of antennas to receive a first Bluetooth signal, generating a first directional value of the first Bluetooth signal, using a processing element to evaluate at least one antenna of the antenna cluster based at least partly on the first directional value, selecting a second subset of antennas based on evaluation, using the second subset of antennas to receive a second Bluetooth signal, and generating a second directional value of the second Bluetooth signal. Other embodiments of the device and operations thereof are also disclosed.

Procédé de fonctionnement, cité à titre d’exemple, d’un dispositif comprenant : l’utilisation d’un circuit commutateur pour un premier sous-ensemble d’antennes d’un groupe d’antennes, l’utilisation du premier sous-ensemble d’antennes pour recevoir un premier signal Bluetooth, la génération d’une première valeur directionnelle du premier signal Bluetooth, l’utilisation d’un élément de traitement pour évaluer au moins une antenne du groupe d’antennes sur la base au moins en partie de la première valeur directionnelle, la sélection d’un deuxième sous-ensemble d’antennes sur la base de l’évaluation, l’utilisation du deuxième sous-ensemble d’antennes pour recevoir un deuxième signal Bluetooth, et la génération d’une deuxième valeur directionnelle du deuxième signal Bluetooth. L’invention concerne également d’autres modes de réalisation et d’autres fonctionnements du dispositif.
