1Introduction
This document gives details of theAT 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, theAT 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.
Test Command
AT+<cmd>=?
Check possible sub-parameter values
Read

When enteringAT 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 theAT 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.
