查看“︁Demo:wifi sta”︁的源代码


=== 基本介绍： ===
该系列demo存放在SDK 的路径为：bouffalo_sdk/examples/wifi/sta 。

该系列代码需要将开发板作为STA节点连接到WiFi或者路由器后进行一些基本的通讯数据功能性测试。

以下该系列demo的基本功能说明。

=== MQTT相关Demo说明： ===

==== wifi_mqtt_pub： ====
该demo将开发板作为mqtt中的publisher,向节点内发布主题信息。

要测试该节点需要以下前置：

1.建立一个mqtt服务器

2.使用mqttbox或者其他相关工具从服务器上订阅对应的主题。

3.可以向串口发送指令。

建议本地下载mosquito,在本地搭建一个mqtt服务器，或者使用emqX公用服务器。该案例的defult server是：`test.mosquitto.org:1883`

向串口发送指令连接WIFI并订阅：<syntaxhighlight lang="bash" line="1">
wifi_sta_connect your_wifi_id your_passwd

mqtts_pub $local_ip 8883   #mqtt_pub  如果不带参数会默认发送到上述的公有服务器

#会得到以下输出：

bouffalolab />mqtt_pub is ready to begin publishing the time.
Press ENTER to publish the current time.
Press CTRL-C to exit.
mqtt_pub published : "{"hello mqtt by bl616/8 !"}
Now time is 2023-06-16 00:00:00"
mqtt_pub published : "{"hello mqtt by bl616/8 !"}
Now time is 2023-06-16 00:00:03"
mqtt_pub stop publish to test.mosquitto.org
</syntaxhighlight>订阅方会受到当前时间的字符串。

==== wifi_mqtt_sub: ====
和上述一样，但是该案例是submiter ，也就是消息订阅方。

前置条件：同上。

同样向串口发送指令来验证：<syntaxhighlight lang="bash" line="1">
bouffalolab />wifi_sta_connect your_wifi_id your_pwd
bouffalolab />mqtt_sub your_server <port> 

#得到输出

bouffalolab />mqtt_sub listening for '<theme>' messages.
Press CTRL-C to exit.
Received publish('<theme>'):  {"hello mqtt"}
Received publish('<theme>'):  {"hello mqtt"}
mqtt_sub disconnecting from xxx.your_server
</syntaxhighlight>

==== MQTTS功能： ====
'''上述的两个Demo现已支持TLS加密功能'''，该加密使用'''TLS1.2'''加密套件，未验证 CN name。

开启MQTT的选项在对应文件夹中的CmakeList中：<syntaxhighlight lang="makefile" line="1">
cmake_minimum_required(VERSION 3.15)

include(proj.conf)

find_package(bouffalo_sdk REQUIRED HINTS $ENV{BL_SDK_BASE})

# User
sdk_add_compile_definitions(-DCONFIG_CLI_CMD_ENABLE)
# sdk_add_compile_options(-DMQTT_USE_CUSTOM_SOCKET_HANDLE)
# sdk_add_compile_definitions(-DMBEDTLS_PK_PARSE_C)


sdk_add_compile_options(-DMQTT_USE_MBEDTLS)     #注释该行则不启用TLS加密，否则加密。

target_sources(app PRIVATE
                   wifi_mqtt_pub.c)

sdk_add_include_directories(.)

sdk_set_main_file(main.c)

project(wifi_mqtt_publisher)

</syntaxhighlight>

</syntaxhighlight>上述函数被调用用来执行测试，更改该部分代码可以实现更改测试目标的目的。

=== TCP的Demo说明： ===

==== wifi_tcp: ====
该部分代码编写了一个server.c和一个client.c,分别用于测试TCP服务端测试和客户端测试。

前置条件：PC端和开发板共同在一个局域网内，可以向串口发送指令。

使用picocom工具在串口中执行指令。

server测试：<syntaxhighlight lang="bash" line="1">
bouffalolab />wifi_sta_connect your_wifi_id your_wifi_pwd
bouffalolab />wifi_tcp_echo_test 3365

#服务器建立成功

bouffalolab />tcp server task start ...
Server ip Address : 0.0.0.0:3365

# 执行 nc -v ipaddr port 连接板子的tcp服务器

=== UDP的demo说明： ===
该部分代码将使用开发板作为sta节点连接wifi并且架起一个udp服务器。

前置条件：PC端和开发板在同一个局域网内，可以向串口发送指令。

测试过程：<syntaxhighlight lang="bash" line="1">
#连接开发板终端并发送指令

bouffalolab />wifi_sta_connect your_wifi_id 12345678

=== OTA的demo说明： ===

==== wifi_ota： ====
该部分代码测试了基本tcp升级固件，使用pc端作为服务器，在同一局域网下，通过命令使得开发板连接ota服务器，接收固件包。

用于测试的固件包被放在了编译出的 build/build_out 目录下。

前置条件：PC端和开发板在同一个局域网内，可以向串口发送指令。

测试过程：<syntaxhighlight lang="bash" line="1">
#该程序需要分区表，所以在编译之后需要执行make whole来烧录whole bin
make whole
cd build/build_out
cat wifi_ota_bl616.bin.ota | nc -nvl 3365   #在pc端架服务器并发送固件

#向串口发送指令连接WiFi并连接服务器开始测试
bouffalolab />wifi_sta_connect your_ssid your_passwd
bouffalolab />wifi_ota_test PC_ip_addr 3365

#收到以下回复则表示测试成功
