"中移物联的M5310是一款基于NBIOT技术的通信模块，其AT指令集主要用于设备配置和管理。该文档详细介绍了加载有V100R100C10B657和V150R100C10B120固件的Hi2110芯片支持的AT命令。在启动时，模块会输出‘M5310<CR><LF>OK<CR><LF>’字符串，表明已准备好接收AT命令。如果因非正常开机序列导致应用核心重启，会有额外的信息输出。在固件更新过程中，模块会发送不同的状态信息，如下载中、下载失败、下载完成、更新中、更新成功、更新失败和更新结束等。在FOTA（ Firmware Over The Air，空中固件升级）过程中，直到收到‘FIRMWARE UPDATED’报告，设备才应恢复操作。此文档还包含了M5310 AT命令集的历史版本更新记录，由林子伟在不同日期进行了多次修订，增加了对B656和B657 SP1固件的支持以及修改了+NSOSTF示例等内容。" 本文档主要涵盖了以下知识点： 1. **M5310模块**：中移物联的M5310是一款专为NBIOT网络设计的通信模块，能够通过AT命令进行控制和配置。 2. **AT指令集**：M5310支持一系列AT命令，如请求制造商识别(+CGMI)，请求制造商模型(+CGMM)，请求制造商修订(+CGMR)和请求产品序列号(+CGSN)等，这些命令遵循3GPP标准。 3. **启动过程**：模块启动时，会输出特定的字符串，表示AT命令处理器准备就绪。 4. **固件更新过程**：在固件更新期间，模块会向外部MCU发送状态信息，包括下载中、失败、完成、更新中、成功、失败和更新结束的状态提示。 5. **FOTA流程**：在空中固件升级过程中，设备需等待“FIRMWARE UPDATED”报告发出后才能继续操作，确保固件更新的完整性和稳定性。 6. **历史版本信息**：文档记录了AT命令集的多个版本，显示了对固件的持续优化和改进，例如增加了对不同版本固件的支持。 7. **作者与更新**：由林子伟在2017年多次更新文档，进行了功能增强和错误修复，确保了M5310模块的兼容性和性能。 8. **3GPP一致性**：M5310的AT命令响应遵循3GPP规定，保证了与3GPP标准的兼容性。这些知识点是理解和使用M5310模块进行NBIOT通信的基础，对于开发人员和维护人员来说，掌握这些内容可以有效地进行模块配置和故障排查。

<revision>: the total number of characters, including line terminators, in the information text

shall not exceed 2048 characters.Text shall not contain the sequence 0<CR> or OK<CR>

M5310 Implementation



<revision> will change format over time. It should be treated as an opaque identifier.

2.4 Request Product Serial Number (+CGSN)

Command

Response

Example

+CGSN[=<snt>]

when <snt>=0 (or omitted) and command

successful:

<sn>

when <snt>=1 and command successful:

+CGSN: <imei>

when <snt>=2 and command successful:

+CGSN: <imeisv>

when <snt>=3 and command successful:

+CGSN: <svn>

+CME ERROR: <err>

AT+CGSN=0

123456789012334

+CGSN:49015420323751

+CGMR=?

when TE supports <snt> and command successful:

+CGSN: (list of supported <snt>s)

AT+CGSN=?

+CGSN:(0,1,2,3)

Description

Execution command returns the IMEI (International Mobile station Equipment Identity number) and related

information

For a TA which does not support <snt>, only OK is returned. Refer to Chapter 6: Error Values for possible <err>

values.

M5310 AT COMMAND SET

Defined values

<snt> integer type indicating the serial number type that has been requested.

returns <sn>

returns the IMEI (International Mobile station Equipment Identity)

returns the IMEISV (International Mobile station Equipment Identity and Software

Version number)

<sn> The 128-bit UUID of the UE. The total number of characters, including line terminators, in

the information text shall not exceed 2048 characters. Text shall not contain the sequence

0<CR> or OK<CR>

<imei> string type in decimal format indicating the IMEI

<imeisv> string type in decimal format indicating the IMEISV

<svn> string type in decimal format indicating the current SVN which is a part of IMEISV;

release.

2.5 EPS network registration status (+CEREG)

Description

The set command controls the presentation of an unsolicited result code +CEREG: <stat> when <n>=1 and

there is a change in the MT's EPS network registration status in E-UTRAN, or unsolicited result code. +CEREG:

<stat>[,[<tac>],[<ci>],[<AcT>]] when <n>=2 and there is a change of the network cell in E-UTRAN.

The parameters <AcT>, <tac> and <ci> are provided only if available. The value <n>=3 further extends the

unsolicited result code with [,<cause_type>,<reject_cause>], when available, when the value of <stat>

changes. Refer to Chapter 6: Error Values for possible <err> values.

M5310 AT COMMAND SET

If the UE wants to apply PSM for reducing its power consumption the set command controls the presentation of an

unsolicited result code:

+CEREG:<stat>[,[<tac>],[<ci>],[<AcT>][,[<cause_type>],[<reject_cause>][,[<Active-Time>],[<Periodic-TAU>]]]].

When <n>=4 the unsolicited result code will provide the UE with additional information for the Active Time value

and the extended periodic TAU value if there is a change of the network cell in E-UTRAN. The value <n>=5 further

enhances the unsolicited result code with <cause_type> and <reject_cause> when the value of <stat> changes. The

parameters <AcT>, <tac>, <ci>, <cause_type>, <reject_cause>, <Active-Time> and <Periodic-TAU> are provided only

if available.



NOTE 1: If the EPS MT in GERAN/UTRAN/E-UTRAN also supports circuit mode services and/or GPRS

services, the +CREG command and +CREG: result codes and/or the +CGREG command and +CGREG:

result codes apply to the registration status and location information for those services.

The read command returns the status of result code presentation and an integer <stat> which shows whether the

network has currently indicated the registration of the MT. Location information elements <tac>, <ci> and <AcT>, if

available, are returned only when <n>=2 and MT is registered in the network. The parameters

[,<cause_type>,<reject_cause>], if available, are returned when <n>=3.

Test command returns supported parameter values.

Defined values

<n>: integer type

disable network registration unsolicited result code

enable network registration unsolicited result code +CEREG: <stat>

enable network registration and location information unsolicited result code

+CEREG: <stat>[,[<tac>],[<ci>],[<AcT>]]

enable network registration, location information and EMM cause value information

unsolicited result code

+CEREG: <stat>[,[<tac>],[<ci>],[<AcT>][,<cause_type>,<reject_ca

use>]]

For a UE that wants to apply PSM, enable network registration and location information

unsolicited result code

+CEREG: <stat>[,[<tac>],[<ci>],[<AcT>][,,[,[<Active-Time>],

[<Periodic-TAU>]]]]
