decocare issue when retrieving CGM data from MDT CGM

[Bender1061]

Issue that I see happen all the time, this error happens almost every loop hence we have to have pump-loop try again when it fails.
but even when we try again, it fails a lot. This is one of the reason it takes so long to update the Nightscout site, with most data being 10 or more mins old.
Now I'm not sure if this is all MDT cgms or just my 723 with 2.4A 1.1

I'm not familiar enough with python to figure out where to go from the decocare lib.py line 235

But here is the error that happens.

Starting supermicrobolus pump-loop at Sun Oct 15 12:41:01 EDT 2017 with 15 second wait_for_silence:
MDT CGM configured; not waiting
Radio ok. Listening: .No pump comms detected from other rigs
Preflight OK.
