Blinky lights

Wisp1 LED uses and meanings

The Wisp1 has three LEDs, Green, Red and Blue.   Their blinking rate will convey status.

  • Green is the overall "system" LED.  
  • Red is for GPS status.  
  • Blue is for the Si5351 transmitter status.  

My intention is to have the LEDs active for the first 30 minutes after the tracker is powered on.  After that, they will be disabled to conserve power.
