FAQ

Bluetooth connection and devices

Check if the device is in advertising mode (Bluetooth symbol blinking), if your master has a compatible Bluetooth module (revision 4.0 or later) and operating system (at least Windows 7, OS X 10.9, iOS 6.0, Android 4.4).

Some older systems (e.g. Windows 7) sometimes need to update the drivers of their Bluetooth modules to ensure compatibility with Bluetooth Low Energy HID devices. Look for an updated driver package for your wireless module.

Check the keyboard layout used by your master device. Sylvac instruments are designed to work with English (US) keyboards. Other keyboard layouts might work too, but some keyboard layouts (e.g. French) do not produce correct values

Make sure to use an English (US) keyboard layout for best compatibility. In tolerance mode the device transmits the tolerance judgement using additional characters.

Check the enabled keyboard layout. Some systems (e.g. Windows) can handle a different keyboard layout for each program or application; others (e.g. Android) use a keyboard layout per input device.

Several factors can influence the achievable range of a Bluetooth connection, e.g. large metallic parts, walls or other wireless devices. If you use a Bluetooth low energy dongle, do not place it next to any USB 3.0 device, this might cause interferences and considerably shorten the range of your connection.

The values from Sylvac Bluetooth devices in HID mode are transmitted like keystrokes from an external keyboard. They are received and interpreted by the currently active application. If keystrokes are received by an application that is not designed to display text, behavior is unpredictable. Make sure to put the text input cursor in the application that should receive the value before sending it.

In HID mode, Sylvac measuring devices behave like a Bluetooth keyboard. Therefore most platforms disable the on-screen keyboard. On some of them (e.g. Android) this behaviour can be changed, whereas on others (e.g. iOS) the on-screen keyboard cannot be used together with an external keyboard.

Remove the pairing established in former connection from the master device(s) (smartphone, tablet or PC) and the measuring device (menu BT – Reset) if this error is displayed when trying to connect.

Error code on instrument

See below for error codes, possible reasons and trouble-shooting

Err.bt 0: Current consuming connection parameters. Battery life might be reduced. Press any key to acknowledge this error.
Err.bt 1: General Bluetooth error. Disconnect and reconnect the device. Remove the pairing established in former connection from the master device(s) (smartphone, tablet or PC) and the measuring device (menu BT – Reset) if this error is displayed when trying to connect.
Err.bt 2: Bluetooth initialization error. Restart the device.
Err.bt 4: Bluetooth memory error. Disconnect and reconnect the device.
No.data: Value could not be sent via Bluetooth® Technology. Check the Bluetooth® connection on instrument and master device (on/off). Check if you are within the max. transmission range 5-15m.
No.bt: Bluetooth module is not connected. Connect to a compatible master device.
—–: Initialization in progress. Message disappears automatically. Press a button if no value is displayed after five seconds.

The Bluetooth module is starting up

Solution:

This message should disappear automatically:

This message should disappear automatically. Press any button if the message is still displayed after 20 seconds.

Softwares and applications

Make sur your measuring device uses Simple or Paired profile (not HID). Check for updates on www.sylvac.ch. Vmux v1.43 and Sylcom v1.3.1 or later are compatible with all Sylvac Bluetooth devices.

Simply click on “Developer resources” in the footer of the website. All resources are then available on the GitHub platform.

Recent Sylvac instruments use different Bluetooth profiles (Simple, Pair, HID). An instrument in HID profile cannot be connected by a program or application. Check or change the active configuration in the BT.CFG menu. Select the Single or Pair profile for connection with Sylcom or Sylvac Anywhere. Remove any existing pairing for HID mode from the central device (master) (PC, smartphone). 

In HID mode, Bluetooth devices store pairing information to reconnect. When the profile is changed, the user must remove the coupling of the earlier HID connection from the central device (master) (PC, smartphone).
