Abstract
A method of communication in a Bluetooth Low Energy (BLE) network comprising a master device and a plurality of slave devices. The method has the steps of: generating a unique identifier parameter comprising a data string having a plurality of bits; assigning to each slave device a unique bit of the unique identifier parameter and a value of the bit representative of active communication; sending from the master device to each slave device a communication which includes the unique identifier parameter; at each slave device, determining the value of the bit assigned to the respective slave device; at each slave device, if the determined value of the bit is representative of active communication, processing the communication, otherwise ignoring the communication.

A method of communication in a Bluetooth Low Energy (BLE) network comprising a master device and a plurality of slave devices, the method comprising the steps of:
- generating a unique identifier parameter comprising a data string having a plurality of bits;
- assigning to each slave device a unique bit of the unique identifier parameter and a value of the bit representative of active communication;
- sending from the master device to each slave device a communication which includes the unique identifier parameter;
- at each slave device, determining the value of the bit assigned to the respective slave device;
- at each slave device, if the determined value of the bit is representative of active communication, processing the communication, otherwise ignoring the communication.
A Bluetooth Low Energy (BLE) network comprising a master device and a plurality of slave devices, wherein:
- the master device is adapted to:
- generate a unique identifier parameter comprising a data string having a plurality of bits;
- assign to each slave device a unique bit of the unique identifier parameter and a value of the bit representative of active communication;
- send to each slave device a communication which includes the unique identifier parameter,
- and wherein each slave device is adapted to:
- determine the value of the bit assigned to the respective slave device;
- and
- if the value of the bit is representative of active communication, process the communication, otherwise ignore the communication.
A method of communication in a Bluetooth Low Energy (BLE) network comprising a master device and a plurality of slave devices, the method comprising the steps of:
- assigning to each slave device a common connection interval having common anchor points;
- assigning a portion of each connection interval as a slave interval for slave to slave communication, wherein a different slave interval is assigned to each of the plurality of slave devices;
- and
- during the respective slave interval, sending a communication directly from one slave device to one or more other slave devices.
