Dana Heartbeat
+ +Dana(RS-v3 / -i) heartbeat modes¶
+Please read the full page and only activate this if truly needed
+Enabling this feature will put a big load on your iPhone's battery or your pump's battery. +Therefore, only use it if your sensor doesn't provide a heartbeat, i.e. the NightScout remote CGM, Dexcom Share, etc
+Danakit provides two ways to enable a heartbeat:
+-
+
- Background sound +
- Continuous Bluetooth mode +
Which mode to choose?¶
+You should choose Background sound when:
+-
+
- You prefer a higher phone battery drain over a higher pump battery drain +
- You are able to change the permission of the Loop app in Xcode or change the Github action build step +
You should choose Continuous Bluetooth mode when:
+-
+
- You prefer a higher pump battery drain over a higher phone battery drain +
- You are aware that the pump's UI will be blocked 24/7 unless you: disconnect in the Loop app, kill the Loop app, or disable bluetooth on your phone +
Background sound¶
+An extra feature available for the Dana pumps is the background sound. +This feature was developed in order to keep the Loop app running in the background.
+Normally, your CGM will have an active Bluetooth connection, which prevent the Loop app from being put into a suspended state. +But when you are planning on using a CGM, like NightScout remote CGM, Dexcom Share, etc, you rely on a active internet connection, and not on an active Bluetooth connection.
+In order to activate, follow these steps:
+-
+
-
+
Activate the UIBackgroundMode - audio:
+-
+
-
+
When building with Mac, go to the LoopWorkspace Xcode project and select the Loop project. +Go to "Targets" -> "Loop" -> "Signing & Capabilities" and scroll down to "Background modes". +Enable the checkbox for "Audio, AirPlay, and Picture in Picture". +Then rebuild the app and go to step 2. +
+
+ -
+
When building with Browser, you will need to make a change to the GitHub Actions workflow. +Go to your LoopWorkspace fork on GitHub and press
+.on your keyboard. +You will be redirected to agithub.devpage with the code of your LoopWorkspace. +Now go to ".github" -> "workflows" -> "build_loop.yml". +Scroll down till you see the- name: Fastlane Build & Archivecommand. +Just before this command, add the following to this script (example):
+
+- name: Update entitlement background sound + run: sed -i -e 's/<string>bluetooth-central<\/string>/<string>bluetooth-central<\/string><string>audio<\/string>/g' Loop/Loop/Info.plist +-
+
- To save your changes to the "build_loop.yml", go to the Source Control tab on the left (should show up with a blue 1, see image below).
+Enter a message and press the green "Commit & Push"-button.
+By pressing this button, GitHub will automatically make a new browser build for you and push it to TestFlight
+

+
After you have done the onboarding of the pump (see steps above), go to the pump settings. + Scroll down the "Pump name" and long-press this row. + A modal should pop-up with the question, whether you want to toggle Silent tones.
+In order to activate this feature, the modal should say something like:
+Yes, Enable silent tones. +When it says:Yes, Disable silent tones, it will disable the background sounds. +
+ -
+
Done! + Every time you put the Loop app in the background, it will play a toneless sound, which prevents it from suspending the Loop app
+
+
Continuous bluetooth mode¶
+This mode replicates how a CGM works: it keeps the bluetooth connection open even though no command's are being executed. +Like stated before, this will drain your pump's battery more than usual.
+How to unblock the pump's UI¶
+If you want to replace the reservoir or want to interact with the pump's UI, you have three options to temporary disable Continuous bluetooth mode:
+-
+
- Disable bluetooth on your phone (not recommended) +
- Kill the Loop app (not recommended) +
- Using the disconnect feature (recommended) +
To use the disconnect feature, go to the Dana pump settings and use the Disconnect from pump button. +You will get prompt to set a notification reminder. +This reminder will be sent to you if you haven't reconnected the pump within the given time. +This feature is fully optional, but is recommended.
+
How to enable Continuous bluetooth mode¶
+Now that you know what the risks are of this feature and how to unblock the pump's UI, can we talk about enabling the feature.
+Go to the Dana settings and long press the Firmware version row.
+You will be prompted to enable or disable the feature, choose Yes, Switch to continuous mode and the feature has been enabled!
