LoopFollow Features

Most features and the settings that control them are self-explanatory and documented within the app. Some documentation is provided below.

Alarms

When you select the Alarms Feature, the initial screen will be blank. By tapping on the plus sign upper right, you can add as many alarms as desired. There is quick access to the overall Alarm Settings by tapping the gear icon on this screen.

The graphic below shows a few typical alarms that might be chosen.

When you tap on a given alarm, you can customize the settings in a number of ways. An example for the Low BG Alert is shown below. Once you customize and alarm, you can enable or disable it quickly while maintaining your custom settings.

There are separate pages for the 3 different remote control options. (No page is provided if None is selected). Quick access is provided using these links once you have configured LoopFollow for Remote Control:

Statistics

The Statistics screen displays a variety of plots and values. This requires an associated Nightscout Site. If the Nightscout site is limited in the days of data, it will be noticeable in the Data Availability metric on the first row.

Background Refresh

LoopFollow has traditionally provided an option to play a silent audio as a trick to allow it to wake up when in the background or when the phone is locked. This has several drawbacks including battery drain and limited reliability.

With LoopFollow version 2.2.9 or newer, an additional method is provided using an external device to provide a heartbeat. This can be a radiolink device, if you have one available, or a used Dexcom Transmitter (G5/ G6/ ONE/ Anubis) or Sensor (G7/ ONE+). The batteries on Dexcom devices continue to provide power to the Bluetooth system, giving a heartbeat at about 5 minute intervals. The radiolink devices provide a heartbeat every minute.

Bluetooth Heartbeat

Why was this added?

LoopFollow can use a background silent audio to keep iOS from killing the app, but this trick puts an extra load on the phone battery and it is known to stop working in some cases, such as when using a Timer on your phone

  • If the silent tune is working well for you, there’s no need to change
  • If you’ve been experiencing significant battery drain you may want to use a Bluetooth Heartbeat

How does it work?

  • You can choose to use a radiolink device or an expired Dexcom device as a heartbeat
  • This can save significantly on the battery used by LoopFollow and provides more reliable ability to wake up LoopFollow out of background mode to check for alarm status.

What devices are supported?

These devices can provide a constant Bluetooth connection for your LoopFollow phone:

  • Radiolink: RileyLink, OrangeLink, Emalink
  • Dexcom Device (the battery can last for months after it is no longer in service with a sensor)
    • Dexcom G5/G6/ONE/Anubis transmitter
    • Dexcom G7/ONE+ sensor

If you use LoopFollow on your Looping phone for the features offered, you can connect to your own Dexcom device. You don’t need to use an expired device in addition.

How do I configure Bluetooth Heartbeat?

These graphics walk you through how to select the Background Refresh Type. The example shows the steps if you choose to use a Dexcom Device (G5/G6/ONE/G7/ONE+). A similar process is used for a radiolink device.

If the person using LoopFollow is also wearing a Dexcom or radiolink, they should choose their own device. The RSSI is a measure of the strength of the signal. It is normal for the Dexcom device to disconnect. It will reconnect regularly.
