Will not connect after recharging

I have owned the BP unit for more than a year and have had this problem from the beginning. Everytime I recharge the battery it will not start a BP measurement even though it says it is connected through Bluetooth. I have to fiddle with it for at least an hour before the unit starts to take a measurement. It is extremely frustrating to the point Im surprised I still have.
