My 101 is losing characteristics

After I upload my sketch, I can spent as long as I like with the first application that pairs. As long as I stay with the first Android tablet, my second can scan it. But after I put the first Android to sleep, I lose all advertisements from the 101.

When it's gone from Bluetoo Analyst from FAQware, I give up.

I'm powering the unit with a 9V battery that services all the 5V and 3.3 V devices, including the 101. I can't draw any current from the board and get transmissions ... I don't hear ever the beep, beep, 5 second beep that tells me your board has power.

I bought two boards, so the power to drive sensors is missing from both, but I haven't moved the wiring to the second 101 to reproduce the Smart Bluetooth amnesia.

Anyone with insight, or I'll go back to Uno and adapters: I've popped out GATT before.
