7.5. Start frames

When the node starts to work in the parking slot, it will send 2 frames. The first one is dedicated to the sensor and the battery.
The second one is used to send some parameters about the chosen configuration.

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:
Reference 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.
Reference 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.
Reference 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. The value stored in these two bytes is an
unsigned 16-bit value.
