6.4.4 Procedure

  1. Modifications for each board.
    1. For CC3100Boosterpack: Remove jumper J6
    2. For CC3200LaunchPad: Remove resistor R62 and connect ammeter across jumper J12
  2. Configure multimeter to measure DC current and set higher current range.
  3. Check for the current direction, wrong current direction will lead to negative currents.
  4. Release RESET and execute the code.
  5. Once device enters into the configured low power mode, reduce current range and note down the current numbers.
  6. Before you exit from low power mode/RESET the device increase the current range on multimeter to higher value.
