MySentry Disable for Medtronic 754/723/554/523:
Medtronic x54 and x23 pumps have a feature called MySentry which initiates broadcasts from the Pump at predetermined intervals.  This requires the OrangeLink or any RileyLink Compatible device to “listen” continuously for these messages.  This “listening” for messages prevents the OrangeLink from powering-off the Radio chips on the board to conserve power.  With the power to the radio chips on all the time the OrangeLink will only last a few days on a pair of batteries.   It is highly recommended if you’re using a Medtronic 754/723/554/523 pump to disable MySentry in your Apps Code.
