* When NullRDC is in use, the radio will be always on. As a result, the algorithm discussed above will always choose PM0 and will never attempt to drop to PM1/2. * When NullRDC is in use, the radio will be always on. As a result, the algorithm discussed above will always choose PM0 and will never attempt to drop to PM1/2.
* The LPP driver is also supported but in order to use it, one needs to set `LPM_CONF_MAX_PM` to 0. Setting a higher value will result in "Sleep Forever" situations. This is inefficient and as a result LPP is not recommended for situations requiring low energy consumption. The main reason for this behaviour is a [bug in LPP][lpp-rf-off-bug]. Once this has been resolved, simple modifications to the LPM module will be implemented to support all three PMs under LPP.
