I am not getting the lowest current in Standby Doze or Deep Sleep on my BL600 / BT900, why?

Answer

In order to realize the lowest possible Standby Doze or Deep Sleep current in the BL600 or BT900, you must have all your SIO pins in their default state. You can find the default state of each pin in the Pin Definitions table in the Hardware Integration Guide / Datasheet for each module.
