Please refer to document [2] for details about AT+CEDRXScommand.
3.4.4. Sleep Mode
BG96 is able to reduce its current consumption to a lower value during the sleep mode. The following
sub-chapters describe the power saving procedure of BG96 module.
3.4.4.1. UART Application
If the host communicates with module via UART interface, the following preconditions can let the module
enter into sleep mode.
 Execute AT+QSCLK=1command to enable sleep mode.
 Drive DTR to high level.
The following figure shows the connection between the module and the host.
Figure 3: Sleep Mode Application via UART
Driving the host DTR to low level will wake up the module.
 When BG96 has URC to report, RI signal will wake up the host. Please refer to Chapter 3.14 for
details about RI behavior.
 AP_READY will detect the sleep state of the host (can be configured to high level or low level
detection). Please refer to AT+QCFG=“apready” command in document [2] for details.
