Chapter 4 Troubleshooting and FAQs Troubleshooting 67

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.

Mobile broadband with GNSS issues

I can’t connect to a mobile broadband network

• Mobile broadband is only available if you purchased your C5m/F5m with the optional

Mobile Broadband with GNSS module.

• A mobile broadband network requires you to have a data plan from a cellular network

provider.

• You’ll need a SIM card from your network provider. See Using the SIM card slot on

page 52. The SIM card contains your account information.

• Ensure that Mobile Broadband with GNSS is enabled in Motion Dashboard. Open

Motion Dashboard, select Wireless, click Enable Mobile Broadband with GPS.

I changed my SIM card and now I can’t connect to my mobile broadband network

• The tablet should be shut down when changing or inserting the SIM card. Restart the

tablet to enable the SIM card.

The GPS doesn’t work

• The GPS receiver is only available if you purchased your C5m/F5m with the optional

Mobile Broadband with GPS module.

• The GPS navigation or mapping application you are using must be able to handle

standard NMEA GPS information.
