Microbit unresponsive after computer wakes from sleep

[ericrosenbaum]

Expected Behavior

When you wake a computer from sleep that had a bluetooth device connected before sleep, it should still be connected (or if necessary, it should become explicitly disconnected).

Actual Behavior

When I have a microbit connected and then the computer goes to sleep (for, say, an hour), on waking, the status indicator still shows connected, but the blocks no longer work for sending or receiving.

Steps to Reproduce

• Connect a microbit to Scratch
• Put the computer to sleep for a long time (an hour?)
• Wake the computer

Operating System and Browser

Mac OS 10.13.2 Chrome 67.0

I wonder if this is related to scratchfoundation/scratch-link#82
@ericrosenbaum @cwillisf,

or, at least, if it can be solved by reconnecting, now

This might already be somewhat fixed by the 5 second 'alive' check in the microbit
