A new release

       The release with the number is a significant update of the previous version - with more than 2500 new lines of code.
        In this new version, the main improvements regard the Nordic Thingy: 52 SensorTag.
       Now, from the SensorTag, we can acquire and display the quaternions, gravity vector, rotation matrix, and heading angle. All this information are presented by the blessTags application in a new panel, see the following figure. This panel is active only in the full version of the blessTags app.

        The quaternions and gravity vector can also be displayed in graphical format too – with all the options that already exist in all graphical data display (auto scale, filtering, traces show, color, and weight).

       Also, to be able to correlate the information between {acceleration, gyroscopic movement, magnetic position}, and {quaternions, heading angle, gravity vector and heading angle} a “send to clipboard” function was implemented in “More movement data” panel.

        Several robustness improvements were made in the acquisition process from Nordic Thingy: 52 SensorTag. Therefore, all the code was: (a) reorganized in several different threads, and (b) several time delaying operations were removed and optimized. One of the results: a new configuration option was introduced.
       Because one of the most time-consuming operations is data displaying on the user interface, when the acquisition frequency is very high (like in the situation of Nordic Semiconductor Thingy:52 SensorTag) the blessTags application will be unable to take in time the entire steam of data events, due to the time spent in data displaying operations. To solve this problem, in an all-day acquisition the data from sensors will be posted to the user every 250 ms (four times in a second) – this approach is also the default one for the Lite version of the blessTags. To circumvent this approach, please check the box “Display text information in real time” from the configuration panel – see the following figure. Now, the data will be posted at the acquisition frequency set by the user. 

This option (“Display text information in real time”) is used only for the Nordic Semiconductor Thingy:52 SensorTag and affects only the display operations. The data acquisition frequency is the one selected by the application’s user, and this option does not influence it.
     Based on all these improvements, the acquisition of the movement process (especially at higher speed) is more stable and reliable.
     The saving function (presented only in the full version) was updated too. First, the blessTags data, acquired now from quaternions and gravity vector (starting with the version, can be saved along with all the other information obtained from the SensorTags. Second, all the saving processes are implemented in a different thread – as a result, the saving function has almost no impact on Bluetooth data acquisition process.
     The temperature, starting with this version, can be displayed in Kelvin and Rankine for all SensorTags.
       Several issues were corrected:
  1. Two errors related to buffers overflow, when interrogating an unknown Bluetooth Low Energy device – these errors appeared only in the development mode;
  2. Several displaying errors (a data overlapping and a spelling error);
  3. One error in saving function – the error was related with data buffer size allocation;
  4. Two problems in the help menu, also the help was improved; 
  5. A deficient conditioning in the CC2650 configuration panel;
  6. A reading method error - from data transfer function between the blessTags and the Texas Instruments SensorTags (CC2650STK and CC2541DK). Now the reading method, of data transfer, is working flawlessly.

What is it the blessTags application main advantage comparing with other similar application?

     The main advantage and, in the same time, the main “feature” of the blessTags is given by the fact the blessTags application is a software package in continuous development – it is not a dead project. The blessTags was improved, and it is, and it will be improved continuously based on the user's feedback, the wishes to implement new useful features and to increase the speed and the reliability of the application and, not in the last, to correct the potential errors. As a good example, in a few days, a new version with substantial improvements will be released.
      The Gadget gives another significant advantage to the blessTags comparing with other application on the market. The Gadgets are several practical and independent applications able to use one or more sensors from a specific SensorTag, in order to achieve a fully functional, and useful application.

     Not in the last, the ability to work with six different SensorTag it is another significant advantage. The blessTags application can manage the following SensorTags: CC2541DK, CC2650STK (both produced by Texas Instruments) Thunderboard React, Thunderboard Sense (Silicon Labs), Thingy:52 (Nordic Semiconductors) and  WICED Sense2 (Cypress).

BlessTags' discovering problem, for a paired SensorTag

The problem:

     Potential issue: the blessTags application is unable to connect to a specific SensorTag. The SensorTag paired with success (so, the Windows side is OK), but nothing appears in the “3. Select the specific device” field.

     For example, in the previous figure a Nordic Thingy:52 SensorTag is paired with the Windows 10 operating system, but even if we select this type of SensorTag, the blessTags application is unable to discover such kind of device.
     Each type of device (e.g., Nordic Thingy:52 or CC2650STK) has a specific variety of features or characteristics. The blessTags application must manage correctly (configure, get data, etc.) each of them. But to do this, the blessTags app must know with each SensorTag is connected, to use the correct set of services and characteristics specific for the corresponding Bluetooth LE device.
     The SensorTag identification is made, by the blessTags application, through the Generic Access service (UUID = 00001800-0000-1000-8000-00805f9b34fb or UUID = 0x1800) – to be more specific using the Device Name characteristic (UUID = 0x2A00), see the following figure (Generic Access service for Nordic Thingy:52).

     If Device Name characteristic string is not one of the known strings (see the following figure with the predefined IDs for each known SensorTag), by the blessTags application, the specific SensorTag is not recognized by the Windows application and is not listed in the “3. Select the specific device” field.

     The reasons for a such situation: (a) the user changes the SensorTag name (it is possible on ThunderBoard React, ThunderBoard Sense, and Nordic Thingy:52), (b) a firmware modification of the SensorTag and (c) the SensorTag has an older version of the firmware, on which the device has another name – like in CC2650STK case.



  1. First, we must find the new name for the Sensortag (the Device Name characteristic string). To do this:
  • Push “1. Refresh SensorTag List” button;
  • In the field “2. Select type of SensorTag” choose “Unknown BLE device(s)” option, in the “3. Select the specific device” field an unknown Bluetooth LE device appears (“BLE device 0 [unknown]”);
  • Check the box “Enter in Developer Mode” from the main user interface;
  • A new window will open (the Developer panel) from here pushing the “Get Generic Access data” button. As a result, the following information will be presented:
  • From here we see that the Device Name (the string from the characteristic 0x2A00) is Thngy (an “i” is missing) not the Thingy – the default name that comes from the producer. So, at this moment we must change the SensorTag Device Name or change the name on which blessTags application recognize the SensorTag – we will choose here the second option.
  1. Second, update the blessTags application database with the new device name from the SensorTag. You have two option to get to the panel that allows you to do that.
  • From the “Developer panel” push the “blessTags configuration” button. From the new window that opens, check the “Removing part of the restrictions from the blessTags application” box;
  • From the main user interface, please push the “?” button => push the graphical icon with the BLE mark => from the new window that opens, check the “Removing part of the restrictions from the blessTags application” box.
  1.  From the last box (right down) labeled “Nordic Thingy:52” change the text from “Thingy” to “Thngy” and push the “OK” button.
  2. Now the blessTags application can quickly discover the Nordic Thingy:52 SensorTag without any problems.

A new release of the blessTags application

      In this version, the software is able to manage a wonderful new SensorTag: Nordic Thingy:52 – produced by Nordic Semiconductor. The following SensorTag’s characteristics are supported:  accelerometer, gyroscope, magnetometer, orientation, temperature, humidity, barometer, color, key, output lines, LED, and the sensor configuration. The integration with gadgets was done at the level of compass, wireless presenters for PowerPoint and remote control for PC applications.
      The blessTags applications fully support events (able to trigger a visual or/and an audible warning or/and a data recording process) and activities (several different actions will be executed when a specific event will take place) for the Nordic Thingy:52 SensorTag.
     Two new options (only in the full version) were introduced in the configuration panel. These options allow to: (a) set the priority for the blessTags application and (b) remove several of the blessTags restrictions. 
    Regarding the first option, from the configuration menu, based on it a priority level for the application can be selected. Five different priorities are allowed:   Realtime - highest priority, High, Above normal, Normal (the program priority by default) and Below normal. This option can be used mainly to improve the speed of the data acquisition, especially when we use a faster SensorTag like Nordic Thingy:52 (with a movement data acquisition up to 200 Hz) or a modified software version for the CC2650STK.
     The second configuration option removes several software restrictions, such as (a) the lower limit used to acquire the acceleration for the CC2650STK or (b) the Device Name (0x2A00 characteristic) – right now a custom name can be used for each SensorTag.

2 Instances of the blessTags app. – a practical application

    Starting with the blessTags version a new configuration option was introduced. This option (the first option from the figure presented below) allows executing one instance or many instances (the number of instances it is not limited) of the blessTags application. The blessTags Lite application allows only one instance of the application to run at one-time moment. 

    In this mode, an instance of the blessTags application can manage one type of SensorTag (e.g. CC2650STK) and another instance of the blessTags application can manage another SensorTags (e.g. ThunderBoard Sense).  Using this approach, you can supervise several parameters from a plant, simultaneously in two different places, and generate warnings or sends emails when a specific state is recognized.

Media Player Classic control

    Another practical application is presented in the following.  In the Gadgets tools set, using the Remote Control application several different Windows programs (3 different types of media players, PowerPoint or Adobe) can be controlled using the buttons from a SensorTag. Other specific remote control commands can be easily defined by a user.
    In the following movie, it is presented a practical application to control the Media Player Classic using two different SensorTags. The first SensorTag is used to play/pause a movie or to get to the next video. To do this a specific predefined list sets of commands is used. The second SensorTag is used to control the volume of the Media Player Classic – one button for volume up and the second button for volume down. The association between the buttons and the Media Player Classic’s volume commands is done using the user-defined list of remote commands.

    Please watch the movie, do it all the steps presented and enjoy a custom application of two instances of the blessTags app.
