A method for operating a sensor system, the system comprising: a Bluetooth Low Energy, BLE, network, a Wireless Sensor Network, WSN, based on a WSN protocol, a central node which is BLE enabled, a plurality of end nodes (104, 134, 136, 138) comprising a transceiver and an antenna for communication with other nodes of the WSN and a BLE peripheral module and a BLE antenna for point-to-point communication BLE communication links with the central node; the method comprising: performing first operations by the Wireless Sensor Network, WSN, to (a) remotely configure operations of the end nodes (104, 134, 136, 138), and (b) remotely control BLE communication link activity within the BLE network; whereby the establishment of the BLE communication links is at least partially controlled by a WSN-linked control application of the WSN; whereby the WSN controls and/or changes the signal power of a BLE peripheral module and/or the antenna pattern of a BLE antenna based on information received from the BLE central node and/or a BLE peripheral module; and performing second operations by the BLE network to (a) find people or objects within a facility and (b) provide services to users of mobile communication devices which are BLE enabled and reside within the facility. a Bluetooth Low Energy, BLE, network, a Wireless Sensor Network, WSN, based on a WSN protocol, a central node which is BLE enabled, a plurality of end nodes (104, 134, 136, 138) comprising a transceiver and an antenna for communication with other nodes of the WSN and a BLE peripheral module and a BLE antenna for point-to-point communication BLE communication links with the central node; the method comprising: performing first operations by the Wireless Sensor Network, WSN, to (a) remotely configure operations of the end nodes (104, 134, 136, 138), and (b) remotely control BLE communication link activity within the BLE network; whereby the establishment of the BLE communication links is at least partially controlled by a WSN-linked control application of the WSN; whereby the WSN controls and/or changes the signal power of a BLE peripheral module and/or the antenna pattern of a BLE antenna based on information received from the BLE central node and/or a BLE peripheral module; and performing second operations by the BLE network to (a) find people or objects within a facility and (b) provide services to users of mobile communication devices which are BLE enabled and reside within the facility. performing first operations by the Wireless Sensor Network, WSN, to (a) remotely configure operations of the end nodes (104, 134, 136, 138), and (b) remotely control BLE communication link activity within the BLE network; whereby the establishment of the BLE communication links is at least partially controlled by a WSN-linked control application of the WSN; whereby the WSN controls and/or changes the signal power of a BLE peripheral module and/or the antenna pattern of a BLE antenna based on information received from the BLE central node and/or a BLE peripheral module; and performing second operations by the BLE network to (a) find people or objects within a facility and (b) provide services to users of mobile communication devices which are BLE enabled and reside within the facility.
