This reverts commit 500f8307c1472cde20db6fccc04994f7af95a79b.
Changed timing

Added  more time in-between temp takes and sending out messages to
extend battery life.
Bad battery timestamp

Finally have bad battery timestamp working on all 3 batteries.  Also
aded very short delay so you can see activity led of incoming data.
Otherwise it blinks too quickly.
