Bluetooth wireless tips
Motion Computing and its Bluetooth partners have worked to ensure a positive experience
with this technology and to ensure Bluetooth interoperability. In doing so, we have found
the following issues:
• Interference—If you’re running Bluetooth and Wi-Fi at the same time, interference can
affect the Bluetooth performance. This is most noticeable if:
– You try to transfer large amounts of data, such as with file transfers
– Several Bluetooth devices are operating in an office simultaneously
• Speech Recognition—Bluetooth audio has not been fully developed for speech
recognition. Therefore, for speech recognition, we recommend that you not use a
Bluetooth wireless headset.
• Disconnection—Some Bluetooth devices will disconnect when they go into power-
saving mode. Most devices will automatically reconnect when they become active again.
• Incompatible drivers—If you attempt to install other wireless headset or other audio
drivers (such as Bluetooth or USB) over the Tablet PC audio drivers, a malfunction of the
Tablet PC audio system may occur because the drivers may not be compatible.
• Interoperability—If you’re having issues with interoperability of Bluetooth devices,
contact the manufacturer of your Bluetooth device and check its compatibility with the
Bluetooth software installed on your Tablet PC.
• Security—Bluetooth devices use a passkey to create a secure connection between the
Tablet PC and the Bluetooth device. Although the passkey exchange helps to secure
your data, Bluetooth wireless technology shouldn’t be considered completely secure.
