Passive determination of pairing and channel parameters for short-range wireless communications

Systems and methods can support identifying pairings and channel parameters in short-range wireless communications such as Bluetooth low energy interfaces. Radio frequency sensors may be positioned within an electromagnetic environment where a master wireless device and a slave wireless device share short-range wireless communications. Signals transmitted between the master wireless device and the slave wireless device can be received by the radio frequency sensors. Inter-arrival times for packets within the received signals may be identified. Statistics of the inter-arrival times can be analyzed to identify connection intervals between the master wireless device and the slave wireless device, as well as back-to-back intervals exchanged within the connection intervals. Packet header contents may be used to reconcile the estimated timing parameters and time slots. Pairings between the master wireless device and the slave wireless device may be identified and tracked along with communication channel parameters.
