Last night we did another test on the full system and discovered a bug. Sequence of Events:

  1. Reset device
  2. Device is off
  3. Turn the device on
  4. Sensor is enabled and working, led is on
  5. Turn off the device
  6. Sensor is disabled, led is off
  7. Turn on the device
  8. Led is on, the sensor is not responding

Problem solved: We found out that we did not enable TIMER3 when the device was turned on for the second time, creating an infinite timeout.
