LPWA Module Series
BG95 Hardware Design
BG95_Hardware_Design 35 / 88
EPC not supporting e-I-DRX, the UE shall apply its regular discontinuous reception.
If e-I-DRX is supported by the network, then it can be enabled by AT+CEDRXS=1 command.
Please refer to document [2] for details about AT+CEDRXS command.
3.4.4. Sleep Mode
BG95 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 BG95.
3.4.4.1. UART Application
If the host communicates with the module via UART interface, the following preconditions can let the
module enter sleep mode.
 Execute AT+QSCLK=1 command to enable sleep mode.
 Drive MAIN_DTR pin high.
The following figure shows the connection between the module and the host.
Figure 3: Sleep Mode Application via UART
 When BG95 has URC to report, MAIN_RI signal will wake up the host. Please refer to Chapter 3.15
for details about MAIN_RI behavior.
 Driving the host MAIN_DTR low will wake up the module.
 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.
