<InformativeText>

<Summary>The CGM Status allows the Collector to actively

request the current status from the CGM Sensor, particularly

when the CGM measurement is not running and the status cannot

be given in the measurement result in the Status

Annunciation.</Summary>

<Value>

<Field name="Time Offset">

<InformativeText>The Time Offset Field specifies the actual

relative time difference to the session start

time.</InformativeText>

<Format>uint16</Format>

<Unit>org.bluetooth.unit.time.minute</Unit>

<DecimalExponent>0</DecimalExponent>

</Field>

<Field name="CGM Status">

<InformativeText>The structure of the CGM Status Field shall

be identical to the structure of the Status Annunciation

Field, as defined in the CGM Measurement Characteristic

three octets regardless the value.</InformativeText>

<Requirement>Mandatory</Requirement>

<Format>24bit</Format>

</Field>

<Field name="E2E-CRC">

<InformativeText>If the device supports E2E-safety (E2E-CRC

Supported bit is set in CGM Feature), the status is secured

by a CRC calculated over all fields.</InformativeText>

<Requirement>C1</Requirement>

<Format>uint16</Format>

</Field>

</Value>

<Note>

<p>C1: Mandatory if device supports E2E-CRC (Bit 12 is set in

CGM Feature) otherwise excluded.</p>

<p>The fields in the above table are in the order of LSO to

MSO. Where LSO = Least Significant Octet and MSO = Most

Significant Octet</p>
