3.5. Power Saving
3.5.1. Sleep Mode
DRX on EG06 is able to reduce the current consumption to a minimum value during the sleep mode, and
DRX cycle index values are broadcasted by the wireless network. The figure below shows the relationship
between the DRX run time and the current consumption in sleep mode. The longer the DRX runs, the
lower the current consumption will be.

3.5.1.1. UART Application
If the host communicates with the module via UART interface, the following preconditions can let the
module enter into sleep mode.
Execute
AT+QSCLK=1
command to enable sleep mode.
Drive DTR to high level.
The following figure shows the connection between the module and the host.
