- Libre 3 or Dexcom G7 as heartbeat
- Libre 3 as heartbeat: avoids the need for audioPlayer that keeps the app alive in the background. When Libre 3 sends data, xDrip4iOS will wake up and fetch a reading from LibreView
- Dexcom G7 as heartbeat: only useful in combination with Loop. Loop must read the Dexcom G7 readings and upload to NightScout. xDrip4iOS will wake up when G7 sends data and will fetch the latest reading from NightScout. This occurs with a delay (Thread.sleep) of 1 second, to give time to loop to upload the reading to NightScout. Sometimes xDrip4iOS is still to early to fetch the reading. In that case, it may help to delete the heartbeat and recreate it.
- OmniPod as heartbeat: for OmniPod users, this is a useful additional heartbeat. OmniPod has the interesting 'feature' to disconnect and reconnect every few minutes. Which allows to call the heartbeat function.
- M5Stack as heartbeat: this is implemented as part of the M5Stack transmitter, it does not appear in the list of heartbeat devices. M5Stack will wake up xDrip4iOS if it didn't receive a reading from xDrip4iOS for more than 5 minutes. This allows xDrip4iOS to download the latest reading and send it to the M5Stack. Needs the latest release of M5stack or M5Stick-C software : https://github.com/JohanDegraeve/M5_NightscoutMon or https://github.com/JohanDegraeve/M5_StickC_xdrip_iOS
- the change required also to re-enable alarms, notifications, badge counter, ... when user has chosen followerBackgroundKeepAliveType disabled
- To use Libre 3 has heartbeat:
- First connect to Libre 3 with official Libre 3 app
- when connected, go to the iOS settings and read and note the name of the Libre (it's not something with ABBOTT in it, it's more like a random string)
- force close the Libre 3 app
- in xDrip4iOS, go to the bluetooth section
- add a new transmitter of type HeartBeat
- select Libre 3
- as transmitter id, fill in the name you read in the iOS settings, just 4 or 5 characters is enough. It's case insensitive.
- click the scan button. (you will not be asked to do NFC scan)
- wait till connected
- now reopen the official Libre 3 app
- To use Dexcom G7 as heartbeat:
- make sure you connected at least once to the Dexcom G7 with the official Dexcom app and/or Loop.
- Not necessary to force close other apps (like Official Dexcom G7 app and Loop)
- go to the iOS settings and read and note the name of the Dexcom G7. It's case insensitive.
- in xDrip4iOS, go to the bluetooth section
- add a new transmitter of type HeartBeat
- select Dexcom G7
- as transmitter id, fill in the name you read in the iOS settings.
- click the scan button. (you will not be asked to do NFC scan)
- wait till connected
- To use OmniPod as heartbeat:
- Force close any other app that connects to the OmniPod (that should only be Loop)
- - in xDrip4iOS, go to the bluetooth section
- add a new transmitter of type HeartBeat
- select OmniPod
- click the scan button
- wait till connected
- you can now reopen Loop
- add 5 seconds to last Readings timestamp, because due to the way timestamp for libre readings is calculated, it may happen that the same reading shifts 1 or 2 seconds in next reading cycle
- add tracing, can be deleted later on
Following instructions are copied from Spike :
On your Apple Watch or the Watch app in your iOS device select the
"Modular" watch face and make sure you also select the "Calendar Complication" to be present in the middle of the watch face
Your glucose values should now start syncing to your watch when you receive your next reading from your CGM transmitter.
If by any chance you're not getting readings in your Apple Watch, go to the Watch app and under "General", "Reset"
click the "Reset Sync Data" and wait a few minutes.
When enabled, all logging can be viewed on a Mac:
- install Apple Configurator 2 on a Mac (it's not necessary to run the application)
- Open a Terminal session (on Mac click Search button top right, type 'Terminal', double click on the Terminal app)
- change directory to Downloads folder , type :
cd Downloads
- copy paste this :
/Applications/Apple\ Configurator\ 2.app/Contents/MacOS/cfgutil syslog | grep xDrip-NSLog | awk -F "xDrip-NSLog " '{print $2}' > xdriplog.txt
and press enter
Now use the app, all logging information can be found in the file xdriplog.txt
You can also leave out the redirection to file.
