3.5. Power Saving
3.5.1. Sleep Mode
UG96 is able to reduce its current consumption to a minimum value during the sleep mode. The following
sub-chapters describe power saving procedures of UG96.
3.5.1.1. UART Application
If the host communicates with module via UART interface, the following preconditions must be met to let
the module enter into sleep mode.
⚫
Execute AT+QCFG="uart/power",0,0 to set UART into auto on/off mode.
⚫
Execute AT+QSCLK=1 to enable the sleep mode.
⚫
Drive DTR to high level.
The following figure shows the connection between the module and the host.

data transfer rate.
The module has registered on the HSPA network and is ready to
send and receive data.
HSPA data transfer is ongoing. In this mode, the power
consumption is decided by network setting (e.g. TPC pattern) and
data transfer rate.
