1 Introduction
This document gives details of the AT Command Set supported by Quectel NB-IoT BC95 module.
The following string will be output after booting the module:
<CR><LF>Neul<CR><LF>OK<CR><LF>
After this string has been received, the AT command processor is ready to accept AT commands.
1.1. Definitions
- <CR>: Carriage return character;
- <LF>: Line feed character;
- <..>: Parameter name. Angle brackets do not appear on command line;
- [..]: Option parameter. Square brackets do not appear on the command line.
1.2. AT Command Syntax
Table 1: AT Commands Syntax
Multiple commands can be placed on a single line using a semi-colon (“;”) between commands. Only the
first command should have AT prefix. Commands can be in upper or lower case.

When entering AT commands spaces are ignored except in the following cases:
- Within quoted strings, where they are preserved;
- Within an unquoted string or numeric parameter;
- Within an IP address;
- Within the AT command name up to and including a „=‟, „?‟ or „=?‟.
They can be used to make the input more human-readable. On input, at least a carriage return is required.
A newline character is ignored so it is permissible to use carriage return/line feed pairs on the input. For
B600, the AT command processor uses carriage return/line feed pairs (\r\n, 0x0D0A) to end lines on its
output.
If no command is entered after the AT token, OK will be returned. If an invalid command is entered,
ERROR will be returned.
Optional parameters, unless explicitly stated, need to be provided up to the last parameter being entered.
1.3. AT Command Responses
When the AT Command processor has finished processing a line, it will output either OK or ERROR
indicating that it is ready to accept a new command. Solicited informational responses are sent before the
final OK or ERROR. Unsolicited information responses will never occur between a solicited informational
response and the final OK or ERROR.
Responses will be of the format:
<CR><LF>+CMD1:<parameters><CR><LF>
<CR><LF>OK<CR><LF>
Or
<CR><LF><parameters><CR><LF>
<CR><LF>OK<CR><LF>
1.4. 3GPP Compliance
3GPP commands are complied with the 3GPP TS 27.007 v13.5.0 (2016-06). For clarification on 3GPP
commands, please refer to this document.

3.6. AT+CSCON Signalling Connection Status
This command gives details of the terminal‟s perceived radio connection status (i.e. to the base station). It
returns an indication of the current state. Please note that this state is only updated when radio events,
such as sending and receiving, take place. This means that the current state may be out of date. The
terminal may think it is "Connected" yet cannot currently use a base station due to a change in the link
quality.
The set command controls the presentation of an unsolicited result code +CSCON. If <n>=1, +CSCON:
<mode> is sent from the MT when the connection mode of the MT is changed. If <n>=2 and there is a
state within the current mode, +CSCON: <mode>[,<state>] is sent from the MT. If <n>=3, +CSCON:
<mode>[,<state>[,<access>]] is sent from the MT. If setting fails, an MT error, +CME ERROR: <err> is
returned. Refer to Chapter 6 for possible <err> values.
When the MT is in UTRAN or E-UTRAN, the mode of the MT refers to idle when no PS signalling
connection and to connected mode when a PS signalling connection between UE and network is setup.
When the UE is in GERAN, the mode refers to idle when the MT is in either the IDLE state or the
STANDBY state and to connected mode when the MT is in READY state.
The <state> value indicates the state of the MT when the MT is in GERAN, UTRAN connected mode or
E-UTRAN.
The read command returns the status of result code presentation and an integer <mode> which shows
whether the MT is currently in idle mode or connected mode. State information <state> is returned only
when <n>=2. Radio access type information <access> is returned only when <n>=3.
Test command returns supported values as a compound value.

3.10. AT+COPS PLMN Selection
Set command forces an attempt to select and register the GSM/UMTS/EPS network operator using the
SIM/USIM card installed in the currently selected card slot. <mode> is used to select whether the
selection is done automatically by the MT or is forced by this command to operator <oper> (it shall be
given in format <format>) to a certain access technology, indicated in <AcT>. If the selected operator is
not available, no other operator shall be selected (except <mode>=4). If the selected access technology
is not available, then the same operator shall be selected in other access technology. The selected
operator name format shall also apply to further read commands (+COPS?). <mode>=2 forces an attempt
to deregister from the network. The selected mode affects all further network registration (e.g. after
<mode>=2, MT shall be unregistered until <mode>=0 or 1 is selected). This command should be
abortable when registration/deregistration attempt is made. Refer to Chapter 6 for possible <err> values.
Read command returns the current mode, the currently selected operator and the current access
technology. If no operator is selected, <format>, <oper> and <AcT> are omitted.
Test command returns a set of five parameters, each representing an operator present in the network. A
set consists of an integer indicating the availability of the operator <stat>, long and short alphanumeric
format of the operator‟s name, numeric format representation of the operator and access technology. Any
of the formats may be unavailable and should then be an empty field. The list of operators shall be in
order: home network, networks referenced in SIM or active application in the UICC (GSM or USIM) in the
following order: HPLMN selector, user controlled PLMN selector, operator controlled PLMN selector and
PLMN selector (in the SIM or GSM application), and other networks.
It is recommended (although optional) that after the operator list TA returns lists of supported <mode>s
and <format>s. These lists shall be delimited from the operator list by two commas.
The <AcT> access technology selected parameters should only be used in terminals capable to register
to more than one access technology. Selection of <AcT> does not limit the capability to cell reselections,
even though an attempt is made to select an access technology, the phone may still re-select a cell in
another access technology.

3.13. AT+CGDCONT Define PDP Context
The set command specifies PDP context parameter values for a PDP context identified by <cid>, the
(local) context identification parameter, and also allows the TE to specify whether security protected
transmission of ESM information is requested, because the PCO can include information that requires
ciphering. There can be other reasons for the UE to use security protected transmission of ESM
information, e.g. if the UE needs to transfer an APN. The number of PDP contexts that may be in a
defined state at the same time is given by the range returned by the test command. Refer to Chapter 6 for
possible <err> values.
For EPS, the PDN connection and its associated EPS default bearer is identified herewith.
A special form of the set command, +CGDCONT=<cid> causes the values for context number <cid> to
become undefined.
If the initial PDP context is supported, the context with <cid>=0 is automatically defined at startup, please
refer to 3GPP TS 27.007 V13.5.0, subclause 10.1.0. As all other contexts, the parameters for <cid>=0 can
be modified with +CGDCONT. If the initial PDP context is supported, +CGDCONT=0 resets context
number 0 to its particular default settings.
The read command returns the current settings for each defined context.
The test command returns values supported as compound values. If the MT supports several PDP types,
the parameter value ranges for each <PDP_type> are returned on a separate line.
