I didn’t have to do anything specific. I did have to tap on the Bluetooth icon in Shuggar and follow the instructions and be particularly patient waiting for it to connect with my phone, but I got there in the end. I then went into the phone Bluetooth settings and checked that the sensor was there and connected, which it was. At first I got notifications every minute which was a bit annoying but you can select how many minutes between each notification within the Shuggar settings. Shuggar seems brilliant apart from that you cannot enter your insulin injections or your carbohydrate consumption. The big issue is that a new sensor must be activated by the LibreLink app that you can’t now use until they fix it, or a reader, which I don’t have.
