涂鸦的Link SDK如何连接到涂鸦IOT平台教程

一 概述

Link SDK

涂鸦Link SDK，即tuya-connect-kit。使用 C 语言实现，适用于开发者自主开发硬件设备逻辑业务接入涂鸦 IoT。Tuya Connect Kit 提供设备激活、DP 上下行和 OTA 等基础业务接口封装，Kit 不依赖具体设备平台及操作系统环境，也可以运行在单任务环境，仅需要支持 TCP/IP 协议栈及提供 SDK 必要的系统依赖接口即可完成接入。

该 Kit 的 C 代码文件通过以下目录结构提供：

certs：设备私钥，设备证书，服务端 CA 根证书

docs：参考文档

libraries：外部依赖库，包含 MQTT client、HTTP client、mbedTLS 等

interface：平台必要移植接口，SDK 功能接口

include：SDK 有文件，包含了 SDK API

src：SDK 源代码

platform：平台移植接口适配

utils：通用工具模块

examples：例程

SDK详细介绍可以参考涂鸦connect-kit官网，这里不作赘述。移植过程中对sdk进行了少量修改，可以使用文件比对工具（例如：beyond compare）比较目录中的文件夹和压缩包中的源码，查看修改了哪里。

二 涂鸦 IoT 平台

1 注册账号

打开涂鸦 IoT 平台官网：https://www.tuya.com/cn/

点击右上角的注册，注册一个账号。注册完毕后，登录。

2 创建产品

1 点击左侧的产品

2 点击创建产品

3 当前组件使用的是 tuya-connect-kit 来连接涂鸦 IoT 平台，涂鸦会根据不同的方案产生不同的激活码，所以这里不能够使用涂鸦已经有的产品进行开发，需要选择其它。（如果希望使用涂鸦的软硬件快速开发，或者0代码开发，直接投产，可以选择下图中已经存在的产品）

4 同样选择自定义品类

5 这里选择产品开发（生态产品接入，会提供mqtt三要素，没有app使用）

6 使用自定义方案

7 完善产品信息，之后点击创建产品

8 选择自己需要的功能，可以选择已经存在的，也可以自定义

9 这里选择公共面板

10 选择Link SDK，选择硬件（这里选择这款硬件，不影响使用自己的硬件）

11 选择指南的任务

12 选择暂不测试

13 免费领取两个激活码，注意选择，授权码清单，之后下载授权码，界面意外关闭，可以按照第三张图找到，之后下载申请的激活码

3 生成二维码

1 二维码规则参考

三 涂鸦组件的使用

1 Gitee链接地址

组件位于amaziot_bloom_os_sdkplatformstuyatuya-connect-kit

Gitee源码地址：https://gitee.com/ning./hongdou

Github源码地址：https://github.com/ayumid/hongdou

当前组件使用涂鸦提供的Link SDK中的tuya-connect-kit实现（Link SDK中还有tuya-open-sdk-for-device）。因为涂鸦平台对不同开发方式进行了识别，所以必须按照本文所描述步骤进行，否则可能无法连接涂鸦平台。

2 服务层组件功能介绍

提供涂鸦Link SDK(tuya-connect-kit)连接实例，实现设备通过app控制等。

该组件为平台组件，可以单独运行，不依赖于其它组件。

3 代码讲解

1 wait_network_ready

等待模组驻网成功，驻网超时后，会软复位模组。

static void wait_network_ready(void) { int count = 0; int ready = 0; while (!ready) { if (getCeregReady(isMasterSim0() ? IND_REQ_HANDLE : IND_REQ_HANDLE_1)) { ready = 1; } sample_mqtt_tls_tuya_catstudio_printf("wait_network_ready: %d s", count++); if (count > 300) PM812_SW_RESET(); OSATaskSleep(200); } }

2 tuya_connectkit_task

调用tuya-connect-kit SDK中的demo，这里可以替换为其它demo。

static void tuya_connectkit_task(void *ptr) { int ret = 0; wait_network_ready(); sample_mqtt_tls_tuya_catstudio_printf("nnnSuccess in the net 2nnn"); // cellular_demo(); switch_demo_non_qrcode(); }

3 tuya_get_csq

获取当前设备的csq值，用于上报信息中的参数。

int tuya_get_csq(void) { char atresbuf[16] = {0}; int err = 0; char *p = NULL; int csqValue = 99; memset(atresbuf, 0, sizeof(atresbuf)); err = SendATCMDWaitResp(TEL_AT_CMD_ATP_10, "AT+CSQrn", 2, "+CSQ", 1, NULL, atresbuf, sizeof(atresbuf)); if(strlen(atresbuf) >= 10 ) { p = strchr(atresbuf,':'); csqValue = atoi(p + 1); } return csqValue; }

4 tuya_get_imei

获取当前设备的imei值，用于上报信息中的参数。

void tuya_get_imei(char *buffer) { char imei[24] = {0}; int err = 0; char *p = NULL; int errorCnt = 0;// wait_reg: memset(imei, 0, sizeof(imei)); err = SendATCMDWaitResp(TEL_AT_CMD_ATP_10, "AT+CGSNrn", 2, NULL, 1, NULL, imei, sizeof(imei)); if(strlen(imei) >= 15 ) { snprintf(buffer, 16, imei); return; } }

5 tuya_get_imei

获取当前设备的iccid值，用于上报信息中的参数。

void tuya_get_iccid(char *buffer) { char iccid[36] = {0}; int err = 0; char *p = NULL; int errorCnt = 0;// wait_reg: memset(iccid, 0, sizeof(iccid)); err = SendATCMDWaitResp(TEL_AT_CMD_ATP_10, "AT+ICCIDrn", 2, "+ICCID", 1, NULL, iccid, sizeof(iccid)); if(strstr(iccid, "+ICCID") != NULL ) { p = strchr(iccid,':'); snprintf(buffer, 21, p + 2); return; } }

6 tuya_send_task

主任务，上电后，代码会一直在while中循环上报csq，用户可以根据自己的业务来修改代码，实现自己的业务逻辑

static void tuya_send_task(void *ptr) { int csq = 0; char imei[16] = {0}; char iccid[21] = {0}; char dp_muti_buf[128] = {0}; char dp_buf[16] = {0}; //"{"103":"866663060145165","104":"898604A41921C0467222"}" tuya_get_imei(imei); tuya_get_iccid(iccid); snprintf(dp_muti_buf, 128, "{"103":"%s","104":"%s"}", imei, iccid); tuya_send_multiple_value_data(dp_muti_buf); while(1) { csq = tuya_get_csq(); snprintf(dp_buf, 16, "{"102":%d}", csq); tuya_send_csq_data(dp_buf); printf("send csq:%d", csq); tuya_sleep(3); } }

4 Demo实战

4.1 创建一个Demo

复制20.4_trans_xtu示例工程，到同一个文件夹下，修改文件名为5.8.3-mqtt_tls_tuya_connect_kit，如图：

4.2 修改makefile

增加mbedTLS，这里不适用tuya-connect-kit中的mbedTLS，使用sdk本身的版本，增加tuya-connect-kit头文件和源文件路径，如图：

4.3 增加头文件

使用代码编辑器，将新建的工程文件加入代码编辑器中，打开main.c，修改main.c，加入am.h等头文件，如图：

main.c

4.4 修改代码

本例对switch_demo_non_qrcode进行了适当的修改，具体查看代码。

4.5 编译

在SDK根目录打开命令行，输入命令.build.bat -l .amaziot_bloom_os_sdksamplelibraries5.8.3-mqtt_tls_tuya_connect_kit

4.6 生成固件

参考入门中开发工具，生成工具。

4.7 扫描二维码，添加设备

app添加设备后，设备上电，demo运行后，会上报一次iccid、imei，之后循环上报设备csq值

5 总结

根据实验现象，按照本文所述流程，可以实现红豆平台连接涂鸦 IoT 平台。

欢迎同学们走进AmazIOT知识库的世界！

这里是为物联网人构建的技术应用百科，以便帮助你更快更简单的开发物联网产品。

Cellular IoT Wiki初心：

在我们长期投身于蜂窝物联网 ODM/OEM 解决方案的实践过程中，一直被物联网技术碎片化与产业资源碎片化的问题所困扰。从产品定义、芯片选型，到软硬件研发和测试，物联网技术的碎片化以及产业资源的碎片化，始终对团队的产品开发交付质量和效率形成制约。为了减少因物联网碎片化而带来的重复开发工作，我们着手对物联网开发中高频应用的技术知识进行沉淀管理，并基于 Bloom OS 搭建了不同平台的 RTOS 应用生态。后来我们发现，很多物联网产品开发团队都面临着相似的困扰，于是，我们决定向全体物联网行业开发者开放奇迹物联内部沉淀的应用技术知识库 Wiki，期望能为更多物联网产品开发者减轻一些重复造轮子的负担。

Cellular IoT Wiki沉淀的技术内容方向如下：

奇迹物联的业务服务范围：基于自研的NB-IoT、Cat1、Cat4等物联网模组，为客户物联网ODM/OEM解决方案服务。我们的研发技术中心在石家庄，PCBA生产基地分布在深圳、石家庄、北京三个工厂，满足不同区域&不同量产规模&不同产品开发阶段的生产制造任务。跟传统PCBA工厂最大的区别是我们只服务物联网行业客户。

连接我们，和10000+物联网开发者一起降低技术和成本门槛

让蜂窝物联网应用更简单~~
