Is flash enable required on the GPS? Reset?

  1. The FLASH_EN is only needed to Flash the GPS.
  2. Reset is needed is you want to exit Flash mode without powering off the GPS. Otherwise not needed in normal operation
  3. The ISM480 powers up in an off state. The On/Off pin needs to be toggled to turn ON the GPS.
    Once the On/Off pin has been toggled you monitor Wake-up pin to change from low to high.
    This indicates the GPS is running and data should start streaming out of the serial port.
