Using a setting of 3 the radio sleeps 2 out of 3 slots, etc.
When the radio is asleep, it hears nothing from the Master.
This table shows the changes at different Low Power Mode settings.
l The actual current draw depends on many factors.
l The table gives only a qualitative indication of supply current savings.
l A low number reduces latency and a high number reduces current
consumption.
Setting Description
0 Low power, disabled.
1 l LEDs dimmed, radio remains awake.
l Radio is listening to the Master’s
transmissions on every slot.
