Unfortuately, in our experience, older Edan monitors seem to have reliability issues with their network connections.
It's frustratingly unpredictable and inconsistent. We at Xchart have seen it happen often enough that we've come to dread this problem because there's so little we can do about it.
Edans made within the last 5 or so years, don't seem to have this issue anymore. But the older ones do. We have not yet been able to identify whether it's a hardware or software issue, all we know is that we've seen it a lot with older model edans. If your monitor is 5 or so years old, it's potentially succeptible to this issue.
It'll often connect just fine, but then intermittently, after a while you'll get a message like this:
To make matters worse, it will often struggle to re-connect after this has occured.
The best thing we know of to fix this problem is to turn the entire monitor off and back on again.
The way our integration with Edan works is as follows:
The sofware establishes a connection with the Edan monitor.
The Edan monitor immediately sends the current vitals readings back over that connection.
The Edan monitor closes the connection.
(this cycle repeats)
What we've seen happen is it will just get stuck at #1. We'll connect, but instead of sending vitals it will just hang and not respond.
Whether you're connecting via the Allink box or Xchart directly, the underlying mechanism is exactly the same.
What should I do if it keeps happening?
You could reach out to Edan's customer support and see if there's a software update available for your monitor.
You could consider getting a different monitor.
