A custom made Bluetooth Low Energy (BLE) wireless sensor network library (MATLAB Simulink) allows to build the models for simulating the communication between multiple BLE devices using a fixed-step (1 us) discrete solver. The library includes configurable blocks of:

  • BLE master and slave devices;
  • sensors;
  • 802.11b interferer;
  • transmission channel (noise, path loss, interference);
  • diagnostics (battery status, BER, PER, PRR, scope of the various signals in the devices).

For generating the initial BLE models, a special MATLAB function can be used, which allows specifying the locations of the devices to take into account the distances between them.
