THE CAREGIVER RECEIVES ALARMS ALTHOUGH HE/SHE ACKNOWLEDGES THEM BY SLIDING ON HIS/HER PHONE

To stop an alarm, it must be acknowledged at the local user’s phone, and at that moment you can select how long that alarm will be deactivated (maximum one hour). If the alarm is only acknowledged in the caregiver’s phone, the system will continue to send alarms to the caregiver until it is acknowledged at the local user’s phone

CAN THE CAREGIVER SELECT THE RANGE OF GLYCEMIA THAT CAUSES AN ALARM?

No, only the local user can set which high and low glucose level generates an alarm.

CAN I MUTE THE ALARMS?

Yes, but not through muting the phone or putting it in do not disturb mode, but silencing the multimedia volume.

For Android: Open the phone sound settings menu and mute “media”.

mute_android

For Iphone: On the control panel (sliding down from any screen), mute the volume.

GNSENTRY LOSES THE BLUETOOTH CONNECTION AND DOES NOT RECONNECT

This problem is common to certain models of Android phones, there is nothing we can do about it since it is due to the management of the Bluetooth connection made from the phone itself, and is solved by restarting the phone periodically. Our recommendation if this is your case, is to restart the phone once a day.

In addition, you should check that the power saving is disabled for the GlucoNightWatch BLU app. Depending on the phone model, the way to access that setup may be slightly different, but the most common is:

Setup -> Additional setups -> Battery and performance -> Manage battery usage by apps -> Power saving modes

You must disable any power saving mode for the GlucoNightWatch BLU app, otherwise the phone, when in stand-by, will sometimes cut the Bluetooth module to save power.

MY ANDROID MOBILE GIVES ERROR 133 WHEN ATTEMPTING TO CONNECT THE GNSENTRY

This problem is common to certain models of Android phones, there is nothing we can do about it since it is due to the management of the Bluetooth connection made from the phone itself, and is solved by restarting the phone periodically. Our recommendation if this is your case, is to restart the phone once a day.

THE READINGS OF GLYCAEMIA ARE DIFFERENT FROM THE ONES FROM ABBOTT READER OR LIBRELINK

The FreeStyle Free sensor is excellent. The raw data that is delivered is extremely accurate considering that the calibration is done at source. But the data it delivers have a “biological age” of approximately 20 minutes on actual blood glucose levels. This is unavoidable, and is well known in all CGM meters as they are based on interstitial fluid measurements.

Therefore, the FreeStyle Libre reader does not limit itself to presenting the data of the sensor, but, based on certain algorithms, tries to estimate the actual value of blood glucose. Abbott has undoubtedly invested a huge amount of resources in the medical studies that have led him to develop these algorithms but, as in any mathematical model, the prediction may not coincide exactly with the real data. Therefore, although most of the time the information offered is very close to the blood glucose measurement, sometimes it differs significantly.

It is inevitable that sometimes they can fail, given that, for example, if we are rising, but at the time of reading we administer insulin, we are “changing the future”, and similarly if we are going down and we eat something.

Therefore, when developing GlucoNightWatch, we chose to present the last raw reading of the sensor, without pretending to make estimates of how the glycaemia has evolved in the last 20 minutes. We think it is an honest and prudent approach, but it implies that we must have an extra degree of foresight, since in 20 minutes variations of more than 50 mg / dl may occur, and it is the responsibility of each user to adjust the levels of alarm taking into account this delay.

MY GNSENTRY DOES NOT RESPOND OR TURN ON ANY LED

Connect the charger for a couple of minutes. Unplug it and reconnect it. The LED should flash rapidly in green and then blink red slowly. Leave it charging until the slow blinking is green, and your GNSentry is again ready for use. If after the second connection to the charger the LED does not light up, please contact us at info@gluconightwatch.com.

IS GNSENTRY COMPATIBLE WITH FREESTYLE LIBRE GENERATION 2?

At the moment it is not compatible with the FreeStyle Libre Generation 2, since it uses a data encoding different from the original FreeStyle Libre.

THE ALARMS CONTINUE SOUNDING EVEN IF I CLOSE THE APP AND REMOVE THE GNSENTRY

For greater security and avoid the accidental loss of alarms, even if the app is closed, it keeps running in the background. If you want to stop using the GNSentry, simply disconnect it from the app’s configuration screen, and reconnect it when you want to use it again.

AFTER CANCELING THE ALARMS DURING THE MAXIMUM PERIOD OF AN HOUR, THE ALARMS CONTINUE TO SOUND

If the maximum period of one hour is insufficient so that after having made some corrective action the blood glucose value returns to the “safe” range, we recommend that you temporarily extend the limits of that range until the blood glucose returns to stable values.

THE GLYCAEMIA READINGS ARE ABNORMALLY LOW AND DO NOT CORRESPOND WITH THE CAPILLARY MEASUREMENT

The FreeStyle Libre sensor is sensitive to prolonged pressure, since that pressure can affect the circulation of the interstitial fluid in which it takes measurements. If you have laid crushing the GNSentry over the sensor, the measurements should return to normal 10-15 minutes after the pressure disappears. Otherwise, it is possible that the sensor has partially detached or moved and it is disabled.

CAN I RECOVER LOST READINGS?

GNSentry only reads the last value of blood sugar, so in periods of voluntary or involuntary disconnection over five minutes it is inevitable that some measures will be lost. We recommend that you continue to use the Abbot reader or your LibreLink app every 8 hours if you want to have a continuous historical record and / or want to generate medical reports. It is not necessary to remove the GNSentry for it, you can read the sensor through it.

HOW DOES GNSENTRY WORK?

GNSentry is an intelligent bracelet that can make periodic readings of the FreeStyle Libre sensor and send them to your iPhone or Android phone. Our App is responsible for evaluating the readings and generating alarms if necessary. GNSentry can be used 24/7 and does not need to be replaced. It is designed to be worn while you play sports, sleep or perform any other activity. It is comfortable and discreet even with tight clothing.

IN ADDITION TO THE BRACELET WHAT ELSE DO I NEED?

1.- GNSentry works with the Free FreeStyle Sensor from Abbott. The FreeStyle Libre is a device that performs readings of glucose levels. For more information about this device, please go to the official Abbott website.

GNSentry is only indicated for users of Abbott’s FreeStyle Libre. If you are not a FreeStyle Libre user, please consult your doctor first before purchasing GNSentry and keep in mind that FreeStyle Libre is not available in all countries.

2.- You will also need an Android phone or an iPhone compatible with Bluetooth Low Energy (BLE) technology.

DO YOU SELL FREESTYLE LIBRE SENSORS?

No. GlucoNightWatch is not related in any way to the company that manufactures these devices nor do we sell them, so their price is not included in any of our packages. If you do not have it, you must acquire one separately.

 

WHAT PHONES ARE COMPATIBLE WITH THE APP?

GNW is compatible with Android phones and iPhones with Bluetooth Low Energy (BLE) technology. However, given the variety of manufacturers of Android phones and versions of the Android operating system, it is possible that your phone has problems to recover the Bluetooth connection with GNSentry, in which case we recommend restarting the phone once a day.

HOW DOES OUR APP WORK?

The application is very easy to use and generates alarms in case of exceeding the upper or lower levels of glycaemia set by the user. The levels that trigger the alarms can be configured in a personalized way. Alarms can be local (on the same phone) or remote (addressed to another device). In addition to the alarms, you have the possibility to see a record of your values during the last days to make sure you are on the right path.

DOES GNSENTRY WORK WITH ANY SENSOR?

GNSentry is compatible with any FreeStyle Free sensor from Abbott. There are slight differences between the different countries but they do not affect in any way the operation of our bracelet.

At the moment it is not compatible with the FreeStyle Libre Generation 2, since it uses a data encoding different from the original FreeStyle Libre.

CAN CHILDREN ALSO USE THE BRACELET?

GNSentry can be used by both children and adults. The bracelet is resistant and can be adjusted to any arm.

GNSentry is only indicated for users of Abbott’s FreeStyle Libre. If you are not a FreeStyle Libre user, please consult your doctor first before purchasing GNSentry and keep in mind that FreeStyle Libre is not available in all countries.

CAN I CUSTOMIZE THE APP’S ALARMS?

Not for the moment. It is a functionality that we have yet to develop.

CAN I REGISTER SEVERAL CARERS?

Yes. You can receive alarms on your phone and also add up to four carers through our ‘cloud system’.

DO I NEED TO WEAR THE MOBILE ATTACHED TO THE ARM?

You do not have to wear your phone in your arm. Just put our bracelet on the sensor and adjust it to the arm with the strap. The readings are sent to your phone via bluetooth.

IS THE BRACELET WATER RESISTANT?

Yes, it is certified as IP67, which means that it can be submerged in fresh water at a maximum depth of one meter for 30 minutes.

HOW OFTEN SHOULD I RECHARGE GNSENTRY BATTERY?

You can use your bracelet for about 15 days without having to recharge it again.

CAN I CONTINUE USING ABBOTT’S ORIGINAL DEVICE FOR READINGS?

Yes, you can continue using the Abbott reader at all times. It is not necessary to remove the GNSentry, the reader of Abbott is able to read the FreeStyle Libre through it.

DOES GNSENTRY WORK ALSO WITH AN SMART WATCH?

No, you can not use your GNSentry with your Smart Watch. You can only use it with your Android Smartphone or your iPhone.

DOES GNSENTRY CARRY SOME SIM CARD?

No, it does not carry any SIM card. Everything works via bluetooth.

DO I NEED THE ABBOTT FREE READER TO INITIALIZE THE SENSOR?

Yes, the first time you have to operate the sensor, you have to use the Abbott Reader to initialize it.

Once this is done, you will not need it again.
