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).

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.

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.
