海外 vSIM EVB 项目推广 example，硬件选型：EC200UEU + Sense HAT(B)
1+
# 快速上手
2+
3+
## 硬件准备
4+
5+
Windows电脑一台，建议 `Win10` 系统。
6+
7+
一套[EC200U-EU Quecpython 标准开发板](https://python.quectel.com/doc/Getting_started/zh/evb/ec200x-evb.html)（含天线，Type-C数据线）
8+
9+
一张能够正常使用的SIM卡
10+
11+
## 环境搭建
12+
13+
- 下载并安装EC200EU系列模组驱动：[QuecPython_USB_Driver_Win10_ASR](https://images.quectel.com/python/2023/04/Quectel_Windows_USB_DriverA_Customer_V1.1.13.zip)。
14+
15+
16+
- 下载并安装 [VSCode](https://code.visualstudio.com/)。
17+
- 下载并解压 [QPYCom](https://images.quectel.com/python/2022/12/QPYcom_V3.6.0.zip) 工具到电脑的合适位置。
18+
- 下载[固件包](../../solutions/SimpliKit/EC200UEUAAR05A01M08_TEST0222.zip )。
19+
- 下载[实验源码](https://gitee.com/dustin-wei/solution-sensorhub)
20+
21+
## 硬件连接
22+
23+
按照下图硬件连接：
24+
25+
<img src="./media/EVB_link1.png" style="zoom: 25%;" /><img src="./media/EVB_link2.png" style="zoom: 20%;" />
26+
27+
28+
29+
1. 将天线连接至标识有 `LTE` 字样的天线连接座上。
30+
31+
2. 使用 Type-C 数据线连接开发板和电脑。
32+
33+
3. 在图示位置SIM1卡槽插入可用的 Nano SIM 卡
34+
35+
36+
37+
## 设备开发
38+
39+
- ### 开机
40+
41+
完成硬件连接工作后，当PWR，SCK1亮起或电脑设备管理器的端口列表出现包含Quectel USB字样的COM口，表示开机成功
42+
43+
<img src="./media/USB.png" />
44+
45+
46+
47+
- ### 烧录固件包
48+
49+
参考[此章节](https://python.quectel.com/doc/Application_guide/zh/dev-tools/QPYcom/qpycom-dw.html#下载固件)，烧录[固件包](../../solutions/SimpliKit/EC200UEUAAR05A01M08_TEST0222.zip )至开发板。
50+
51+
- ### 脚本导入与运行
52+
53+
1.参考[此章节](https://python.quectel.com/doc/Getting_started/zh/first_python.html#PC与模组间的文件传输)，将源码目录下的code文件夹中的所有文件按原目录结构导入到模组文件系统中，如下图所示
54+
55+
<img src="./media/Qpycom.png" />
56+
57+
2.参考[此章节](https://python.quectel.com/doc/Getting_started/zh/first_python.html#执行脚本文件)，执行主程序文件_main.py
58+
59+
3.参考[此章节](https://python.quectel.com/doc/Getting_started/zh/first_python.html#停止程序运行)，停止程序运行。
60+
61+
## 业务调试
62+
63+
### 程序启动
64+
65+
执行_main.py脚本后，程序开始运行，会打印拨号信息，包括拨号状态、IP地址、DNS服务器地址，设备号等
66+
67+
<img src="./media/drivers_data.png" />
68+
69+
### 🚩 **Warning**
70+
71+
未插入SIM卡时，SCK1灯不会亮起，并且无法打印设备信息，插入SIM卡并重启设备后即可正常运行。
72+
73+
<img src="./media/sim_erro.png" />
74+
75+
### 数据检测
76+
77+
开始运行后每1s会打印一次检测到的温度1，湿度，气压，温度2，颜色的三原色的数据,
78+
79+
<img src="./media/data.png" />
80+
81+
### 数据更新
82+
83+
当检测以上4种的任一数据产生大于1或者原色产生大于150的变化时就会尝试上传云端更新数据，当上传成功时返回“send ret：True”，并且会提示是哪些数据发生了变化，APP读取云端最新数据进行数据更新。
84+
85+
<img src="./media/data_up.png" />
86+
87+
<img src="./media/yun.png" />
88+
89+
如果数据没有大于1的变化就会只在pqcom中打印当前检测的数据，不会发起上传云端。
90+
91+
<img src="./media/data1.png" />
92+
93+
位置定位更新，当模组位移超过50米时，云端会刷新定位信息，app读取最新定位信息。
94+
95+
<img src="./media/gnss.png" />
96+
97+
主动刷新APP数据，通过点击APP右上角刷新按键，APP会向服务器发起主动读取数据的指令，用于主动更新面板数据
98+
99+
<img src="./media/APP.png" style="zoom: 67%;" />
100+
101+
温度，湿度，气压，颜色，Lbs数据被获取成功
102+
103+
