  <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>
  </InformativeText>
  <Value>
    <Field name="Time Offset">
      <InformativeText>The Time Offset Field specifies the actual
      relative time difference to the session start
      time.</InformativeText>
      <Requirement>Mandatory</Requirement>
      <Format>uint16</Format>
      <Unit>org.bluetooth.unit.time.minute</Unit>

    </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
      "Sensor Status Annunciation Field". It always consists of
      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>
