CarelinkFollower socket timeouts

[kukuchta]

For quite some time there seems to be an issue with retrieving the data from servers in timely manner using the CareLink Follower source.

As a result, the new datapoints and notifications are not downloaded for about 10-15 minutes, I can see the missed reading effects (BG display in red and so on), and then it goes back to normal, when 2 or 3 missed readings are downloaded. It happens randomly, sometimes 2-3 times per hour. There is also an exception logged:

I have changed the timeouts to:

After some longer tests i can confirm that it solved my issue and I havent seen those Exceptions since applying this fix.

Im using one of the latest official nightly builds:

I am a new user, but recently the Medtronic servers and the application had some connection problems.
I managed to get the Medtronic app working with a workaround few days ago, and the Carelink follower collector works without any problems.
The values in xDrip are updated 15s after the MiniMed app - grace period set at 15s.
Can you confirm the latency problem is still there?
