At the time, no. A structure to enable a degree of customization of the firmware is in the works.
If the system runs out of memory during a log, the log will be automatically terminated and the file will be available for download up to the point of interruption. If the system runs out of battery during a log, when the system is recharged, it will attempt to recover the last file: if the recovery is successful, the file will be available for download up to the point of interruption.
The Bluetooth range greatly depends on the obstacles between the system and the host (usually a PC or a smartphone), but can reach a maximum of 30 meters. Metal objects or peoples in between the system and the host can lead to a reduction in this figure.
You can recharge the system battery by connecting it via a standard USB-C cable. A full system charge will take around 2 hours.
The system, if not connected via Bluetooth, will automatically enter standby after 30 seconds of inactivity. You can force the standby mode by pressing the button for a duration between 2 and 5 seconds. The system can be removed from the standby mode with the same button press
A Windows application is provided with the system in order to control it. A C# (for Windows) and C++ (for both Unix and Windows) SDK are available to ease the integration of the system in other pre-existing applications.
The system can be configured and controlled via Bluetooth commands; we provide a software to seamlessly interface with the system, implementing all the functionalities in a more intuitive way. To avoid using the software on the field, a pre-configured log mode can be started with a press of the button; Bluetooth commands or the use of the software is still needed to configure this mode the first time.
No, log and stream are two different modes of the device, which is capable of handling them one at a time.
Yes. Please note that environmental data is sampled at a fixed 25 Hz rate, meaning that if, for example, a 1600 Hz log is selected, the file will contain a lot of repeated environmental data values due to their up-sampling.
That depends on how big the file is, and how it is downloaded. We suggest using USB for better performances; the entire memory can be downloaded in roughly 15 minutes if using USB, or around 4 hours if using BLE.
The internal memory dedicated to data is 1Gbit. The duration depends on the frequency of data sampling and the number of sensors sampled; a rough estimate of the memory duration can be computed using the following equation:
Where D is the memory duration in hours, Fs is the selected sampling frequency and Ns is the number of sensors logged. Keep in mind that for very low sampling frequencies, it is likely that the battery will run out before the memory
