Technical specifications:

  • Bluetooth v2.1 + EDR. Class 2.

  • TX power: 3 dBm

  • Antenna: 5 dBi

  • Up to 250 unique devices in each inquiry

  • Received Strength Signal Indicator (RSSI) for each scanned device

  • Class of Device (CoD) for each scanned device

  • 7 power levels [-27 dBm, +3 dBm]

  • Scan devices with maximum inquiry time

  • Scan devices with maximum number of nodes

  • Scan devices looking for a certain user by MAC address

  • Classification between pedestrians and vehicles

Bluetooth uses 79 channels with a bandwidth of 1 MHz per channel. In addition, Adaptive Frequency Hopping (AFH) is used to enhance the transmissions.

Bluetooth module for device discovery:

The Bluetooth radio module has been specifically designed in order to scan up to 250 devices in a single inquiry (smart phones, tablets, computers, etc). The main purpose is to be able to detect as many Bluetooth users as possible in the surrounding area.

Related API libraries: WaspBT_Pro.h, WaspBT_Pro.cpp

All information on their programming can be found in document: .

All the documentation is located in the in the Libelium website.

If you want to detect iPhone and Android devices using the WiFi interface as well as the Bluetooth radio go to the "Smartphones Detection" section in the Meshlium website:
