Frames
7.1.4. Error frame
In some cases the node could send a frame if some internal components or processes fail.
Byte Name Description
0 Basic data Detailed description in section “Frame”
1 Frame counter Detailed description in section “Frame”
2 Error data Detailed description below
3 Temperature
Temperature (Celsius degrees) from the node's internal sensor. The
value of temperature is a signed integer.
4 X axis measurement MSB
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.
5 X axis measurement LSB
6 Y axis measurement MSB
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.
7 Y axis measurement LSB
8 Z axis measurement MSB
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.
9 Z axis measurement LSB
10 Battery level
Battery voltage in millivolts. To convert to millivolts use the next
formula:

Bit Name Description
7-6 Reserved Reserved bits. Do not consider.
5 Error Sigfox
Set to '1' when an error related with the Sigfox radio is detected. Clear when no
issues detected.
4 Error LoRaWAN
Set to '1' when an error related with the LoRaWAN radio is detected. Clear when
no issues detected.
3 Error RTC
Set to '1' when an error related with the RTC (internal clock) is detected. Clear
when no issues detected.
2 Error X axis
Set to '1' when an error appears in the X axis of the sensor. Clear when no issues
detected.
1 Error Y axis
Set to '1' when an error appears in the Y axis of the sensor. Clear when no issues
detected.
0 Error Z axis
Set to '1' when an error appears in the Z axis of the sensor. Clear when no issues
detected.
