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 asmartphone), 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.
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.
You can recharge the system battery by connecting it via a standard USB cable. A full system charge will take less than 2 hours
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 around.
:No, log and stream are two different modes of the device, which is capable of handling them one at a time
The internal memory dedicated to data is 1Gbit. The duration depends on the frequency of data sampling and the number of sensors sampled; a very rough estimate of the memory duration can be computed using the following equation:
Where D is the memory duration in hours and Fs is the selected log frequency. Keep in mind that for very low sampling frequencies, it is likely that the battery will run out before the memory
