Wireless sensors not detected on Windows computer with PS-3500 Adapter

None of my Wireless Sensors (AirLink, Smart Cart) are detected by PASCO software on my Windows computer.

When SPARKvue or PASCO Capstone is installed on a Windows computer, the drivers for the BLE (Bluetooth Low Energy) adapter PS-3500 are installed on the computer. If the PS-3500 is placed into a USB port in the Windows computer prior to the installation of SPARKvue or PASCO Capstone, Windows will install the incorrect driver.

The fastest way to resolve this issue is go into the Windows updates and to select the Optional updates.  Please apply updates from "BlueGiga"

If the above does not work, or is not available please try the following.

The following  steps will direct Windows to the correct drivers. Make sure that the PS-3500 is connected to a USB port when following these directions.

  1. Click the Windows/Start button
  2. Select Control Panel
  3. Select Device Manager
  4. Click Ports (COM &LPT) to expand this menu item
  5. Look for the the Bluegiga Bluetooth Low Energy (COM##). If you cannot find the adapter listed, it can be listed as a
  6. Low Energy Device under COM/ PORT section or show up as a USB device.
  7. Right click on it to select "Update Driver Software"
  8. Select "Browse my computer for driver software"
  9. Navigate to "C:\Program Files (x86)\PASCO scientific\Common Files\BLEDUsbDriver" and click OK
  10. Click Next.

Additional Bluetooth Driver Troubleshooting

If the instructions contained above do not get the PS-3500 drivers installed properly, please try the following:

  1. Navigate to C:\Program Files (x86)\PASCO scientific\Common Files\BLEDUsbDriver
  2. Right click on the usbserial.inf file and select Install
  3. Right click on the dfu.inf file and select install

If you are successful in installing the drivers, but are still not able to get the Wireless Sensors to connect to SPARKvue or Capstone, try connecting the PS-3500 in a different USB port.
