Hoffmann Group Connected Tools - Bluetooth®-enabled tools and HCT app

We offer you state-of-the-art, Bluetooth-enabled tools and an innovative app for quick documentation and data transmission.

The innovative products of the Hoffmann Group Connected Tools (HCT) ensure highest precision and support your quality inspection in an unprecedented way. Measurement data can be precisely determined and saved. These measurement data can then be transmitted via Bluetooth to a computer, tablet or smartphone.

Save valuable time for checks, documentation and transmission and benefit from the ease of use of this system.

Specifically, for you this means:

  • More freedom of movement: No annoying data transmission cables.
  • Maximum reliability: No reading errors, no transmission errors.
  • Time saving due to easy documentation: At the push of a button the measurement result is directly transmitted to your PC application (e.g. Excel or Word) or to your smartphone or tablet.

Hoffmann Group Connected Tools App

Quickly and easily organise different tool groups: The new HCT app makes documentation of measurement data easier than ever.

With the help of our HCT app you can enhance your Bluetooth-enabled Hoffmann Connected Tools with additional functions, processes will be integrated into your production process even more efficiently and corporate quality will thus be further increased.

Save time and costs: It only takes a few steps to carry out measurements, save them and send them via Bluetooth to a device of your choice. Whether as an e-mail, an excel file or as a different file format – the measurement data are quickly and securely digitised and thus ensure the quality of your data.

Features of the HCT App

  • Clarity: One app for several tool groups
  • Ease of use: Tools can be operated and set using the app
  • Time saving: Automatic documentation of the measured values
  • Organisation: In future, list and operate your tools by app

Other functions:

  • Live measured values can be read off directly
  • All HCT-enabled devices are immediately visible in a list
  • Every measured value can be sent to the HCT app via the data button Measurement results can be saved and/or sent directly to a PC, tablet or smartphone. This significantly facilitates the creation of measurement protocols.
  • Output option into different file formats (Excel, Word, etc.)

Application example HCT app and GARANT digital caliper

  • The HCT app will enable you to get a live view of the measurement data of your HCT caliper, to operate the caliper by remote-function (such as setting of the pre-set value or the current zero point) or to e-mail the consolidated measured values via data export to a computer of your choice.Changing HID keyboard layout for the French market. Changing the decimal separator from comma to period for English-speaking users.
    (Permitted for digital calipers of the GARANT family with firmware from r.4.00.)

    Functions of the GARANT digital caliper in combination with the HCT app:
  • Display of the live measured value-
  • Remote operation of the caliper: Setting a pre-set value, assigning the zero point-
  • Setting of tolerances from a defined nominal dimension
  • Renaming of the caliper
  • Changing the unit of measurement
  • Changing the Bluetooth connection profile
  • Changing the decimal separator from comma to period
  • Sending the measured value as an amount

GARANT digital caliper with bluetooth

In this video we present our new digital caliper with Bluetooth.

With a simple click you can transfer the measured values of the caliper to your data carrier via Bluetooth. This works not only for the PC, but also for smartphones and tablets.

Technology, FAQ & further information

What type of technology is used?

Bluetooth is a wireless secure connection used for the exchange of data between various devices. The devices used can be from various manufacturers. Bluetooth technology is primarily developed and licensed by the Bluetooth Special Interest Group (SIG).

The prerequisite for a digital device being considered as „Bluetooth-enabled“ is the presence of appropriate software to control the transfer of data, and of a special Bluetooth chip that has a transmitter and receiver unit and is built into the hardware. Some of the well-known manufacturers of such chips are Atheros, Nordic Semiconductor and Toshiba. Bluetooth functionality can also be added to a device by connecting a Bluetooth adapter to the USB interface of the device.

Transferring information via Bluetooth works best across relatively short ranges. The energy-saving exchange via Bluetooth is the ideal solution for the selective, ad hoc transfer of information.

Bluetooth operates at frequencies in the ISM bands between 2.402 GHz and 2.480 GHz. The ISM bands (Industrial, Scientific and Medical bands) are frequency bands that can be used by high frequency equipment in industry, science, medicine and in domestic environments without a licence and (in most cases) without a permit.

Benefits for our customers, derived from using the application:

  • Increased efficiency due to measured values being saved directly in SPC software or from history file
  • Quick and precise change of various tool settings via app control
  • Allocation of individual names for tools
  • Use of standard protocols: These provide the required security when transmitting measured values.

FAQ / Troubleshooting

  • 1. The HCT caliper will not connect to the app.

    Check that the tool is in search mode. This is indicated by the flashing Bluetooth icon in the display.

    Please select the defined and required Bluetooth connection type to establish a connection with the HCT app. Please select the "simple mode" to establish a connection with the HCT app.

    General Bluetooth connection:
    Please check in the Bluetooth settings of the mobile device whether the caliper is still listed under "MY DEVICES". The connection via HID connects the calliper directly to the mobile device. If it is still listed there, delete the device from the "MY DEVICES" list by clicking on the small "i" in the blue circle, "Ignore this device" (IOS) or via Remove device (ANDROID). Try again.

    General Bluetooth setting:
    Please allow "use my location". Location data will not be collected by the use of the app. However, if you do not agree, it may lead to malfunctions in the Bluetooth connection.

  • 2. The HCT device will not connect to the PC.

    Check the correct setting (HID Bluetooth profile).
    If the device was already connected to the PC, delete the device from the device list and add it again.
