Connect LibreLink Time Delay about nightscout-connect HOT 11 OPEN

That 22 minutes probably includes server reboot time to switch between libre linkup systems... so the delay may actually be more like 20 minutes. I did check the system clock on my server and the time is accurate and is GMT. To be clear, I had to wait about 20 minutes for that sample just to the right of 1 to show up on the graph... and the Glucose reading in the upper right was just --.. it never updated.

I do have the same issue. I have setup nightscout for the first time and have no other tooling using the linkup interface. I also uninstalled the LibreLinkUp app from my mobile which I used to setup the account. It's running now for 12h and I get my data in avarage 20 minutes delayed. Any ideas what is going wrong?

I believe this is intentional [by Libre]. Libre does 20 minutes, Dexcom delays Apple HomeKit by a whole 3 hours. This is most likely their way to prevent other apps from making real time decisions on this data. I opened a PR to fix the delay with LinkUp.

And this PR addresses the interval.

That was quick!!! Thank-you for doing this! I'm unfamiliar with the nightscout-connect update process... Is there a way I can tell which version of nightscout will incorporate the changes? Thanks again for your quick response. It's very much appreciated.

I do not know their process, I believe PRs would have to be approved, merged, then released as part of a future NS release. If you're feeling adventurous, here's is a HACKY way to do it, you can go into your NS instance where you installed it, browse into:

<your_installation_folder>/node_modules/nightscout-connect/lib/sources /librelinkup.js

make a backup copy, then replace it with this file from my fork. Or, better, implement the changes from the PRs into your file yourself. Restart the service afterwards and test that it still works. This is a risky way to do it, if your version is not the same as the one I modified, you may ruin your install. I recommend making the same changes yourself, based off of the PRs.

If using pm2 to run it as per NS instructions, if changing the my.env file to add the 1min interval, you may need to delete the pm2 item and readd it. If that's how you run it, per NS instructions, this should do it:

go to your NS folder, where you installed it, then:

lists the active services:
pm2 l

delete the item you want, ID is a zero based integer, left column, replace X with the proper ID:
pm2 delete X

reinstall the pm2 service:
env $(cat my.env) pm2 start lib/server/server.js

then save:
pm2 save

POC: No delay, data extends to 10:45am, and has one entry per minute 😋

I can confirm that your fixes work! I chose to modify my existing librelinkup.js file directly. Thank you for the guidance!!!

Well then, it's off to the races! Glad I could help.

Thanks for the heads up, I've updated README.md as well to notify about the new CONNECT_LINK_UP_INTERVAL parameter.
