1. 安装依赖

sudo apt-get update
sudo apt-get install hostapd dnsmasq

sudo pip install flask

2. 热点功能

教程：香橙派ubuntu22开启热点并设置成开机自启

（1）开启热点（并断开当前连接的Wi-Fi）

sudo nmcli radio wifi off && \
sudo nmcli radio wifi on && \
sudo systemctl stop dnsmasq && \
sudo systemctl restart NetworkManager && \
nohup sudo create_ap wlan0 eth0 Takway-Toys --no-virt > create_ap.log 2>&1 &

（2）运行Web后端

sudo chmod 777 app.py
sudo python3 app.py

app.py

# coding: utf-8
import subprocess
import os
import time
from flask import Flask, render_template, request, redirect, url_forapp = Flask(__name__)# 检测 Wi-Fi 连接状态
def check_wifi_connection():try:# 使用nmcli命令检查Wi-Fi连接状态output = subprocess.check_output(['nmcli', 'device', 'status']).decode('utf-8')# 分析输出以查找Wi-Fi连接状态for line in output.split('\n'):if 'wifi' in line and 'connected' in line:return Trueexcept subprocess.CalledProcessError as e:print(f"Error checking Wi-Fi status: {e}")return False# 设置热点
def set_hotspot():try:subprocess.run(['sudo', 'create_ap', 'wlan0', 'eth0', 'Takway-Toy', '--no-virt'], check=True)except subprocess.CalledProcessError as e:print(f"Error setting up hotspot: {e}")# 扫描 Wi-Fi
def scan_wifi():try:subprocess.run(['nmcli', 'device', 'wifi', 'rescan'], check=True)except subprocess.CalledProcessError as e:print(f"Error scanning for Wi-Fi networks: {e}")# 连接 Wi-Fi
def connect_wifi(ssid, password):scan_wifi()time.sleep(1)try:subprocess.run(['sudo', 'create_ap', '--stop', 'wlan0'], check=True)print("Stopping create_ap service")except subprocess.CalledProcessError as e:print(f"Error stopping hotspot: {e}")time.sleep(1)try:subprocess.run(['nmcli', 'dev', 'wifi', 'connect', ssid, 'password', password], check=True)except subprocess.CalledProcessError as e:print(f"Error connecting to Wi-Fi: {e}")time.sleep(5)# 检查是否成功连接Wi-Fiif check_wifi_connection():print("成功连接到Wi-Fi，程序即将退出。")os._exit(0)  # 成功连接后退出程序else:print("Wi-Fi连接失败。")# 主页
@app.route('/')
def index():return render_template('index.html')# 提交 Wi-Fi 信息
@app.route('/submit', methods=['POST'])
def submit():ssid = request.form['ssid']password = request.form['password']print(f"Connecting to Wi-Fi: {ssid} with password {password}")connect_wifi(ssid, password)return redirect(url_for('index'))if __name__ == '__main__':debug_mode = True  # 设置为 True 以跳过 Wi-Fi 连接状态检测if not debug_mode:if check_wifi_connection():print("已连接到 Wi-Fi 网络")else:print("未连接到 Wi-Fi 网络")set_hotspot()# 创建 index.html 文件index_html_path = 'index.html'if not os.path.exists(index_html_path):with open(index_html_path, 'w') as f:f.write("""<!DOCTYPE html>
<html>

<body><h1>输入 Wi-Fi 信息</h1><form method="post" action="{{ url_for('submit') }}"><label for="ssid">Wi-Fi 名称 (SSID):</label><input type="text" id="ssid" name="ssid" required><br><label for="password">密码:</label><input type="password" id="password" name="password" required><br><input type="submit" value="连接"></form>
</body>
</html>""")app.run(host='0.0.0.0', port=80, debug=True)

3. 开启自启动脚本

方式一：配置系统开机自启动service服务

香橙派——基本配置教程

sudo vim /etc/systemd/system/wifi_hotspot.service

[Unit]
Description=My Service
After=network.target
[Service]
Type=simple
WorkingDirectory=/home/orangepi
ExecStart=python3 /home/orangepi/app.py
User=root[Install]
WantedBy=multi-user.target

第二种

[Unit]
Description=WiFi Hotspot Wrapper
After=network.target
Wants=network.target[Service]
Type=oneshot
ExecStart=python3 /home/orangepi/wifi_hotpot/wifi_manager.py
WorkingDirectory=/home/orangepi/wifi_hotpot
User=root[Install]
WantedBy=default.target

sudo systemctl daemon-reload
sudo systemctl enable wifi_hotspot.service
# sudo systemctl disable wifi_hotspot.service

sudo systemctl start wifi_hotspot.service

sudo systemctl status wifi_hotspot.service

其他常用命令及脚本

扫描Wi-Fi：

nmcli dev wifi rescan

断开WiFi连接

sudo systemctl stop dnsmasq
sudo systemctl stop NetworkManager
sudo systemctl restart NetworkManager

连接Wi-Fi

nmcli dev wifi connect Innoxsz-Public password innox2023
nmcli dev wifi connect Takway-AI password takway123

开启热点：

# 有密码
sudo create_ap -m nat wlan0 eth0 orangepi orangepi --no-virt
# 无密码
sudo create_ap wlan0 eth0 Takway-AI --no-virt
# nohup
nohup sudo create_ap wlan0 eth0 Takway-Toys --no-virt > create_ap.log 2>&1 &
