Medtronic has announced an issue which affects people using the
Guardian Connect continuous glucose monitoring (CGM) system.
Medtronic has advised that there is a potential connectivity
issue, which requires everyone using the Guardian Connect system to
update to version 3.2.2 of the Guardian Connect app as soon as
The identified issue relates to Apple iOS 11.3 & 11.4 that
can sometimes prevent people using the Guardian Connect system from
receiving a 'Lost Communication' alert when the app is closed by
the iPhone's operating system in certain situations.
This means that in certain situations the operating system may
close the Guardian Connect app without alerting the user that the
app is no longer running or communicating with the Guardian Connect
Transmitter. If the app is closed, people using the Guardian
Connect system will not receive alerts that could be associated
with hypoglycaemic or hyperglycaemic events.
Medtronic also advise that people using the Guardian Connect
system periodically check that the app is still running and be
especially mindful when running several applications at once.
If you are using the Guardian Connect system you will have
received an email from Medtronic advising you of what you will need
to do next. If you have not received this email, please contact
Medtronic by calling 1800 777 808.
