SIM800_蓝牙调试笔记

sim800c1. 简介SIM800C是一款功能强大的GSM/GPRS模块，适用于各种无线通信应用。

它支持全球四个频段，可用于数据传输、语音通信和短信服务。

本文将介绍SIM800C的特性、使用方法和常见问题解决方案。

2. 特性•支持四个频段：850/900/1800/1900 MHz•支持GSM、GPRS、TCP/UDP等协议•支持数据、语音和短信传输•支持SIM卡热插拔•内置SIM卡接口和天线接口•支持电源电压范围：3.4V - 4.4V•尺寸小巧便于集成3. 使用方法要使用SIM800C模块，您需要完成以下步骤：3.1. 连接硬件首先，将SIM800C模块与您的主控设备进行连接。

将模块的VCC引脚连接到主控的电源正极，将GND引脚连接到主控的电源地。

然后，将模块的TXD引脚连接到主控的串口发送引脚，将RXD引脚连接到主控的串口接收引脚，确保电平匹配。

3.2. 配置串口在主控设备上，配置串口参数以与SIM800C进行通信。

设置波特率为通信速率，并确保其中一个数据位停止位的选择正常。

3.3. 初始化模块初始化SIM800C模块以准备进行通信。

通过向模块发送AT指令，检查是否收到OK响应。

如果响应正常，表示SIM800C模块已成功初始化。

3.4. 发送指令通过向SIM800C模块发送AT指令，您可以执行各种操作，如发送短信、拨打电话、建立网络连接等。

在每个指令后面加上回车符和换行符，以确保指令能够正确解析。

3.5. 处理响应SIM800C模块会对每个指令作出相应的响应。

您需要根据响应结果来判断操作是否成功。

响应以OK或ERROR等关键字开头，解析响应以获取操作的结果。

4. 常见问题解决方案4.1. 无法连接到网络如果您无法连接到网络，请检查以下几点：•确保SIM卡已插入SIM800C模块并且正常工作。

•确保SIM卡具有有效的套餐和足够的余额。

•检查SIM卡是否正确插入模块，并且天线是否连接良好。

•检查SIM800C模块的电源供应是否正常。

These profiles include settings to parametrize and to control the communication from start. Adherence to profiles saves the time for transmitting the parameters anew before the bi-directional link becomes effective. There are a wide range of Bluetooth profiles that describe many different types of applications or use cases for devices.Besides of all profiles, there have four basic ones, they are GAP/SDAP/SPP/GOEP Profile.1.3.Bluetooth Device AddressThe Bluetooth device address stores the network address of a Bluetooth–enabled device. It is used to identify a particular device during operations such as connecting to, pairing with, or activating the device.A Bluetooth–enabled device address is a unique, 48 bits address containing the following three fields:•LAP field: lower part of the address containing 24 bits.•UAP field: upper part of the address containing 8 bits.•NAP field: non–significant part of the address containing 16 bits.The LAP and the UAP represent the significant address part (SAP) of the Bluetooth device address.1.4.AT Interface for Bluetooth FunctionAs module solution, we provide series of AT interface to operate Bluetooth function, including pairing, bonding, pushing or receiving file.Also including interface for SPP service, which could communicate between Bluetooth device and others via serial port.When the module as a Bluetooth headset role, we provide a set of AT commands to control theremote smart phones, such as phone calls, turn on or hang up calls and so on.By default, the module operates in power-saving mode, which means that the module can besimultaneously connected to a Bluetooth device. When the module to establish a connection with adevice, other devices can not be scanned into the module, the module can not get Profile, will notbe able to establish new connections and modules. If the customer's application scenario, themodule needs to be multiple Bluetooth devices (currently up to three) connection, you need to usethe AT + BTSPPCFG = 1 command to turn off the power saving mode. It should be noted that thepower saving mode does not affect the module initiative to connect to other Bluetooth devices.2.

sim800cAT指令功能：GSM短信收发，GPRS数据传输，TCP/IP协议数据传输，LBS信息的定位，http的java接⼝调⽤，FTP的⽆线升级，模块BT的串⼝协议传输。

1、短信接收发功能“AT+CMGF=1\r” //配置短信形式“AT+CMGL=\”ALL\”\r” //读取所有短信“AT+CSCS=\”GSM\”\r” //进⾏CSCS设置“AT+CMGS=” //后⾯添加信息中⼼短信号码“AT+CMGD=” //进⾏短信删除C语⾔书写解释：@1、每⼀个AT指令后⾯都要以\r或者是\r\n结束。

这是AT标准AT指令集⾥⾯规定的，没有什么疑问。

@2、AT指令后⾯如果是要跟字符串的东西，例如AT+CSCS=”GSM”,这句指令，因为我们发过去给simcom模块的是字符串，最后传⼊的形式是：“AT+CSCS=”GSM””，因为⾥⾯有多个字符串标识（“”）,导致模块识别不了，然⽽⾥⾯的字符串不是真的字符串结束标识符，⽽是我们实际要传⼊的值，所以我们要把这个标识符转义成字符就可以，让其不代表其他意思，加上\转义字符就可以了例如上⾯：”AT+CSCS=\”GSM\”\r”。

@3、AT+CMGF=mode：mode:0 PDU模式1 TXT⽂本模式（经常⽤的）@4、AT+CMGL=”ALL”标识列出所有的信息，包括已读和未读的。

或者是AT+CMGL=“REC UNREAD”会列举出所有未读的消息AT+CMGL=“REC READ”会列举出已读的消息。

后⾯列举的形式：包括短信状态（已读未读），短信Num，消息发送⽅号码，消息发送时间，最后⾯就是紧跟着信息的内容了。

@5、AT+CSCS=”GSM”设置信息服务发送模块，其实这个可以不设置也可以发送，默认的就是这个模式。

@6、AT+CMGS= 号码这个命令执⾏完之后，就像其他传输⼀样会出现⼀个‘>’符号，后⾯就是你要写⼊的信息内容。

注意这个结束有点奇怪。

2、AT+BTHOST? //查询模块名称和地址返回:AT+BTHOST?+BTHOST: Niren,27:a7:2c:90:62:60OK也可以通过该指令修改蓝牙设备名称3、AT+BTSCAN=1,10 //收索蓝牙附件设备，收索时间10S返回:AT+BTSCAN=1,10OK+BTSCAN: 0,1,"MEIZU MX3",22:22:4e:73:13:84,-45 //收索到的设备，设备ID:1+BTSCAN: 1 //收索结束注意：这里需要等待返回+BTSCAN: 1才代表收索结束。

4、AT+BTPAIR=0,1 //主动请求匹配设置ID：1蓝牙设置AT+BTPAIR=0,1OK+BTPAIRING: "MEIZU MX3",22:22:4e:73:13:84,573342注意:这时手机就会收到模块提交的配对请求，手机确认配对即可5、AT+BTPAIR=1,1 //响应连接请求AT+BTPAIR=1,1OK+BTPAIR: 1,"MEIZU MX3",22:22:4e:73:13:846、AT+BTGETPROF=1 //获取配对的蓝牙设备提供的服务返回：AT+BTGETPROF=1AT+BTGETPROF=1+BTGETPROF: 10,"PBAP"+BTGETPROF: 1,"A2DP(Source)"+BTGETPROF: 2,"HFP(AG)"+BTGETPROF: 8,"AVRCP(Target)"OK注意：这里费服务列表中没有我们需要的SPP服务，这需要，先打开手机的蓝牙串口助手，打开蓝牙助手后再重新获取一次服务。

使用Sim800L模块发送短信需要遵循一定的步骤。

首先，需要准备一些必要的工具和材料，包括Sim800L模块、一张有效的电话卡、一个卡套、一个电源适配器以及一些连接线。

在开始使用之前，确保你已经了解了这些工具和材料的基本使用方法。

接下来，需要将电话卡插入Sim800L模块中。

为了确保模块能够正确识别电话卡，需要使用卡套将电话卡固定在模块中。

这个步骤需要小心谨慎，以免损坏模块或电话卡。

在连接电源适配器之后，可以为Sim800L模块提供稳定的电源。

确保电源适配器能够提供适当的电压和电流，以避免对模块造成损坏。

在配置模块参数之前，需要使用串口助手或其他工具通过串口与Sim800L模块进行通信。

这个步骤需要一定的技术知识，因此建议在熟悉相关操作之后再进行。

在配置参数时，需要输入正确的短信中心号码和APN等信息，以确保模块能够正常发送短信。

最后，通过串口发送AT指令来控制Sim800L模块发送短信。

在发送短信之前，需要确保模块已经正确配置并且已经连接到网络中。

在发送短信时，需要注意短信的内容和接收人的号码等信息，以确保短信能够正确发送并被接收人收到。

需要注意的是，使用Sim800L模块发送短信需要遵守相关的法律法规和运营商的规定。

在使用过程中，不得用于违法或违规用途，否则可能会面临法律责任。

同时，在使用过程中，也需要对模块进行定期的维护和保养，以确保其正常工作和延长使用寿命。
