Raw temperature from the parking internal sensor. The value stored in
these two bytes is a 16-bit value in 2's complement form. To convert to
Celsius degrees use the next formula:
Raw value from the sensor associated to the X axis. The value stored in
these two bytes is a 16-bit value in 2's complement form.
Raw value from the sensor associated to the Y axis. The value stored in
these two bytes is a 16-bit value in 2's complement form.
Raw value from the sensor associated to the Z axis. The value stored in
these two bytes is a 16-bit value in 2's complement form.
Battery voltage in millivolts. To convert to millivolts use the next formula:
Description
Reserved bits. Do not consider.
Set to '1' when an error related with the Sigfox radio is detected. Clear
when no issues detected.
Set to '1' when an error related with the LoRaWAN radio is detected. Clear
when no issues detected.
Set to '1' when an error related with the RTC (internal clock) is detected.
Clear when no issues detected.
Set to '1' when an error appears in the X axis of the sensor. Clear when no
issues detected.
Set to '1' when an error appears in the Y axis of the sensor. Clear when no
issues detected.
Set to '1' when an error appears in the Z axis of the sensor. Clear when no
issues detected.
