Some configurations do not have by default the drivers to recognize the device, download and install them if necessary, the drivers are available for download on the page https://www.ftdichip.com/Drivers/VCP.htm depending on the computer’s operating system.

 

If you have the latest version of the driver installed, it may be necessary to change the USB cable if it is not the original one because some cables are not compatible with the data transfer necessary to recover the memory of the device.

 

On Mac, there may be a conflict with the internal driver already present and it is necessary to follow the following procedure:
1) Download the drivers at http://www.ftdichip.com/Drivers/VCP.htm and install them. The installation will succeed, BUT because of the FTDI drivers built into Apple, they won’t work.
2) Restart the computer and enter recovery mode by turning off and holding CMD + R on reboot.
3) In recovery mode, open the terminal from the utilities at the top of the screen and type the following to temporarily disable system integrity protection:
csrutil disable
The computer will ask you to restart for the changes to take effect.
4) On reboot, we now need to disable Apple’s FTDI drivers (NOTE: this can be undone at any time, don’t worry).
Open the Terminal and write the following.
cd /system/library/extensions
sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled
sudo touch /Système/Bibliothèque / Extensions

It is possible to benefit from a recharge of 30, 100 or 500 SMS. 20 SMS are offered with the first year of the Capturs/Sigfox subscription when you purchase a Capturs device.
30 SMS: 4.99€
100 SMS : 14,99€
500 SMS : 69,99€.

Sigfox allows low consumption, long range (about 15 Km) and low data rate data communication. It is not necessary to have a SIM card to transmit data. There are 7 standards on the network, with frequency modulation, depending on the geographical area.
The GSM network is the one used by our phones for communication, with a lower range and higher consumption. It is necessary to have a SIM card compatible with the country of use.

When the device is in an area not covered by the Sigfox network, the data sent by the device cannot be received and therefore visible on the web or mobile interface. However, the device continues to record the positions in its internal memory (the “logger”), and it is therefore possible to recover the trip afterwards thanks to the Capturs software.

The device sends positions in real time every 10 minutes under Sigfox network coverage, with a trace accuracy of 3 minutes.
It is possible to increase this frequency in the PC/Mac Capturs software by connecting your device to your computer.

It is possible to benefit from a subscription for 1 year, 2 years or 3 years. The first year of subscription is offered with the purchase of a Capturs device.
1 year : 23,88€.
2 years : 39,00€.
3 years : 49,00€.

The Sigfox network is a low-power, long-range wireless network. It is dedicated to the Internet of Things (or Connected Objects) also called IoT.

1) Make sure that the “location” is activated,

 

2) Verify that you have authorized the application to access the position

 

3) On Android, go to the power saving settings (watch the picture on the left).

If after logging into your account you notice that your device no longer appears on your account, this is most often due to an error in the choice of connection mode.
So you need to log out with the top right button and choose the connection mode of the account on which the device has been saved: with Google, Facebook or with an email address.

The device can only transmit a position every 10 minutes with an accuracy of about 3 minutes if the “flight” or 3D mode is deactivated. On the interface, straight lines appear between these positions, which can pass over buildings, fields, etc.
As the device has a GPS module, depending on the number of satellites it can fix to find its position, the accuracy of the positions may vary, and may cause a shift off course.
Using your smartphone as a tracker with the mobile application allows you to benefit from a more accurate trajectory. Indeed, the smartphone uses GSM data, so the data is closer together.

The device can only be registered for one user account. If you try to add it to a second account, this message will appear. You must delete it from the old account before you can save it to a new one.

Some configurations do not have by default the drivers to recognize the device, download and install them if necessary, the drivers are available for download on the page https://www.ftdichip.com/Drivers/VCP.htm depending on the computer’s operating system.

If the device does transmit on Sigfox but there are no positions sent at the same time, this may be due to several phenomena specific to devices using satellite positioning systems.
The main position losses come from the stalling of the signals between the device and the satellites, thus preventing the triangulation of the position:
– From GPS fix just after departure, cold, where the device could no longer see the constellation of the satellites, and therefore needs about 3 minutes before starting to move to find their position and thus start to fix its position correctly.
– From the outside environment: trees, buildings and even clouds can prevent the proper reception of data from a satellite and can cause triangulation to be prevented or accuracy to be lost.
