public final class ContinuousGlucoseMeasurementResponse
extends ContinuousGlucoseMeasurementDataCallback implements CRCSecuredResponse, Parcelable

    Response class that could be used as a result of a synchronous request. The data received are available through getters, instead of a callback.

    Usage example: 

    try {
    ContinuousGlucoseMeasurementResponse response = waitForNotification(characteristic)
          .awaitValid(ContinuousGlucoseMeasurementResponse.class);
    float glucoseConcentration = response.getGlucoseConcentration();
    ...
} catch (RequestFailedException e) {
    Log.w(TAG, "Request failed with status " + e.getStatus(), e);
} catch (InvalidDataException e) {
    Log.w(TAG, "Invalid data received: " + e.getResponse().getRawData());
}

      • onContinuousGlucoseMeasurementReceived

         void onContinuousGlucoseMeasurementReceived(@NonNull() BluetoothDevice device, float glucoseConcentration, @Nullable() Float cgmTrend, @Nullable() Float cgmQuality, @Nullable() CGMTypes.CGMStatus status, int timeOffset, boolean secured)

        Callback called when a Continuous Glucose Measurement packet has been received.

        If the E2E CRC field was present in the CGM packet, the data has been verified against it.If CRC check has failed, the onContinuousGlucoseMeasurementReceivedWithCrcError will be called instead.

        The Glucose concentration is reported in mg/dL. To convert it to mmol/L use:

        value [mg/dL] = 18.02 * value [mmol/L]
        or simply call toMgPerDecilitre.

        Note that the conversion factor is compliant to the Continua blood glucose meter specification.

        Parameters:
        device - the target device.
        glucoseConcentration - the glucose concentration in mg/dL.
        cgmTrend - an optional CGM Trend information, in (mg/dL)/min.
        cgmQuality - an optional CGM Quality information in percent.
        status - the status of the measurement.
        timeOffset - the time offset in minutes since Session Start Time.
        secured - true if the packet was sent with E2E-CRC value that was verifiedto match the packet, false if the packet didn't contain CRC field.

      • isSecured

         boolean isSecured()

        Returns true if the packet was secured with E2E CRC.See isCrcValid to check if the CRC was valid.

      • isCrcValid

         boolean isCrcValid()

        Returns true if the packet was secured with E2E CRC value and the CRC was valid.In all other cases it returns false.
