Vector 3 pedals won't pair

I just installed my Vector 3 pedals and they will not pair with any device.  Nothing recognizes them as available to pair.  For instance the Garmin Connect app after I type their ID number and rotate the crank in just sits on "Searching...We are having some trouble locating your device".

The right pedal is flashing a bright green LED 3 times.

The left pedals is flashing a dim red LED repeatedly at alternating speeds.
