description | A method for establishing wireless communications connections between a plurality of sensors of a motion tracking system and a computing apparatus of the motion tracking system, comprising: processing radiofrequency signals received by the computing apparatus and transmitted by each sensor of the plurality of sensors, each radiofrequency signal including an advertisement package of the respective sensor; providing a plurality of RSSI per each sensor of the plurality of sensors based on the processed radiofrequency signals; computing and storing mean RSSI values, RSSImean, based on the pluralities of RSSI so that a plurality of RSSImean values is computed per sensor; computing velocities of change of RSSImean, vRSSI, based on the pluralities of RSSImean values so that a plurality of vRSSI values is computed per sensor; establishing the wireless communications connections between the computing apparatus and a set of sensors of the plurality of sensors for which at least the following is fulfilled: the computing apparatus determines that at least some vRSSI values within a first time period of the plurality of vRSSI values of each sensor of the set of sensors has a modulus greater than a predetermined minimum velocity; wherein the predetermined minimum velocity is equal to or greater than zero. |
