10 Troubleshooting
10.1 Bluetooth
Most internal Bluetooth adapters are compatible with PLUX devices. However, if you’re
experiencing a great number of connection loss events, reconnection problems, missing
samples or similar problems, your internal Bluetooth module might not have enough
performance to deal with the data throughput of the device you are using. In this case,
reducing the sampling frequency or the sample resolution might solve this issue, if a
change of these parameters is possible.
For this reason, PLUX has identified Bluetooth dongles that have been tested and are
known to work with our devices. We recommend that you use one of these PLUX-tested
Bluetooth dongles, which are either already shipped with your device (e.g. in the case of
biosignalsplux kits) or can be purchased separately from our store. These dongles are
compatible to work with data rates up to 24 Mbps.
The solution is to exchange the internal Bluetooth Adapter for an external Bluetooth USB
dongle that uses the Windows native Bluetooth stack. For this, you’ll need to install the
Bluetooth dongle properly, as described in the following steps, which are explained in
more detail throughout the next pages for the supported operating systems:
Step 1: Removing already paired devices from your operating system
Step 2: Installing PLUX-proven Bluetooth dongle
Step 3: Changing Bluetooth Stack to Microsoft’s native Bluetooth stack
NOTE
If you’re already using PLUX devices with the old Bluetooth stack, please remove your
device(s) from your computer before changing the Bluetooth drivers/changing to
Microsoft Bluetooth Stack.
NOTE
We recommend going through all the following steps to set up your Bluetooth dongle
correctly, even if Windows may automatically install and set up your dongle.
NOTE
Installing the Bluetooth dongle and changing the Bluetooth stack is only required for
Windows computers only. Computers with a Mac OS X operating system do not need to
go through these steps and use the internal Bluetooth adapter instead.
