Install an N102 on STM32F103 and experience NB-IoT development at home [Copy link]

Install a 000 intelligent N102 module for STM32F103, and you can experience NB-IoT development at home

With the increasingly perfect deployment of NB networks, many friends are eager to experience NB-IoT development.

Friends who have applied for/purchased the gokit3 development version, today I will teach you a trick to experience NB development at home or school in minutes. Please note that please make sure that NB-IoT is covered during the experiment and that N102 has an authorization code.

First you need to prepare the following materials:

• STM32F103 (GoKit3 baseboard)
• GoKit3 functional version
• Zero Zero Intelligent N102 module
• NB card, DuPont line, USB data cable,
• Computer, Gizwits Cloud development platform account, etc.

232)]After the materials are prepared, just follow the steps below.

1. Overview

This article mainly introduces how to use the Gokit development board and the NB-DTU N102 module to quickly access Gizwits Cloud

[backcolor=rgb(232, 232, 2. Data interaction process between NB module and Gizwits Cloud

The basic data flow of data interaction between device and Gizwits Cloud is shown in the figure below.

APP receives device reported data: device reported data → operator IOT platform → Gizwits Cloud platform → APP end

232)]APP sends device control data: APP → Gizwits Cloud Platform → Operator IOT Platform → Device receives data

3. Create device products on the Gizwits official website, define data points, and add devices.

Here we take the example of "smart light" to introduce the entire process of connecting a device to Gizwits.

1. Create a new product

2. 定义数据点

3. 添加设备

四、下载自动生成mcu代码，烧写程序到Gokit的mcu中

5. Modify the MCU program so that the MCU can control the LED light

Program modification steps, omitted, there is a reference code at the end of this article

Six, connect N102 to MCU, power on the device to go online

VII. Device online, Gizwits IOE DEMO APP binds device

After the module is powered on normally for more than ten seconds, it will automatically connect to the Gizwits Cloud platform. At this time, we can use the Gizwits Cloud APP to scan the QR code to bind GN511, and use the Gizwits Serial Port Assistant tool to generate the device binding QR code (Serial Port Assistant download address https://download.gizwits.com/zh-cn/p/98/119)

After generating the device binding QR code, we can download the Gizwits IOE DEMO APP scan code to bind device
