5.4 Power consumption and power down modes
To reduce power consumption of the BlueMod+C11/G2 power down modes can be
activated automatically by the BlueMod+C11/G2 (controlled by parameter settings).
If no Bluetooth connection is established, the following states are implemented, the
activation of these states can be controlled by the parameters bpsm and pwd.
For more details please refer to the BlueMod+C11/G2 software manual.
