General Description
Overview
- BG95 Mini PCIe is a series of LTE category M1/NB2 module adopting standard PCI Express Mini Card form factor (Mini PCIe). It is optimized specially for M2M and IoT applications and delivers 588 Kbps downlink and 1119 Kbps uplink data rates. It provides data connectivity on LTE-FDD/GPRS/EGPRS networks, and supports half-duplex operation in LTE networks.

Operating Models
The following table briefly outlines the operating modes of the BG95.
| Mode | Detail |
|---|---|
| Normal Operation | Idle |
network, and it is ready to send and receive
data

| Normal Operation | Idle |
network, and it is ready to send and receive
data
Airplane Mode
When the module enters airplane mode, the RF function will be disabled, and
all AT commands related to it will be inaccessible.
W_DISABLE#
W_DISABLE# enables/disables the RF function (excluding GNSS). It is pulled up
by default, and driving it low makes the module enter airplane mode. The pin
function is disabled by default, and AT+QCFG=”airplanecontrol”,1 can be used
to enable this function.
Airplane Mode Control (Hardware Method)
| W_DISABLE# | RF Function Status | Module Operation Mode |
|---|---|---|
| High level (default) | RF enabled | Normal mode |
| Low level | RF disabled | Airplane mode |
The RF function can also be enabled/disabled with AT+CFUN=
| AT+CFUN= |
RF Function Status | Module Operation Mode |
|---|---|---|
| RF and (U)SIM disabled | Minimum functionality mode | |
| RF enabled | Full functionality (normal mode) | |
| RF disabled | Airplane mode |
PERST#
PERST# forces a hardware reset on the module. The module can be reset by
driving PERST# low for 2–3.8 s and then releasing it.
LED_WWAN#
LED_WWAN# indicates the network status of the module. LED_WWAN# supports two
indication modes which can be switched through AT+QCFG=”ledmode”:
- AT+QCFG=”ledmode”,0 (Default setting)
- AT+QCFG=”ledmode”,1
The following tables show the detailed network status indications of LED_WWAN#.
Indications of Network Status (AT+QCFG=”ledmode”,0, Default Setting) Pin Status| Description
---|---
Flicker slowly (200 ms low/1800 ms high)| Network searching
Flicker slowly (1800 ms low/200 ms high)| Idle
Flicker quickly (125 ms low/125 ms high)| Data transfer is ongoing
Always low| Voice calling
Pin Status| Description
---|---
Low Level (Light on)| Registered on network successfully
High-impedance (Light off)| -No network coverage or not registered
-W_DISABLE# is at low level (airplane mode)
-AT+CFUN=0 or AT+CFUN=4
WAKE#
- WAKE# is an open collector signal which is similar to RI, but a host pull-up resistor and
- AT+QCFG=”risignaltype”,”physical” command are required. When a URC returns, a 120ms low level pulse will be outputted. The state of WAKE# is shown as below.
