Python 使用 BLED112 加密狗连接到 BLE 模块并读取/写入 GATT 服务特性的代码

Question

我有一个 BLED112 加密狗和一个 BLE 设备。我的 BLE 设备具有一种服务和两种特性。我需要开发一个 python 脚本，它使用 BLED112 扫描附近的 BLE 设备并连接到我的 BLE 设备。然后我需要找到服务特性并对它们进行读写。

我在 github 中找到了对 BGAPI 和 PYGATT 的支持，但它们看起来非常复杂。

请帮我举一个简单的例子来完成我的任务。

非常感谢。

我能够添加一个文本框和按钮来获取组件并扫描附近的设备以下是我的代码：-

import pygatt
import re 
import tkinter as tk
from functools import partial

def call_result(label_result, n1):
    num1 = str(n1.get())
    label_result.config(text="Comport is %s" % num1)
    adapter = pygatt.BGAPIBackend(serial_port=str(num1))
    adapter.start()
    listOfDevices = adapter.scan()
    print (listOfDevices)
    return

root = tk.Tk()
root.geometry('800x400+100+200')
root.title('Project')
number1 = tk.StringVar()
labelTitle = tk.Label(root, text="Project").grid(row=0, column=2)
labelNum1 = tk.Label(root, text="Enter Comport of dongle").grid(row=1, column=0)
labelResult = tk.Label(root)
labelResult.grid(row=7, column=2)
entryNum1 = tk.Entry(root, textvariable=number1).grid(row=1, column=2)
call_result = partial(call_result, labelResult, number1)
buttonCal = tk.Button(root, text="Get ComPort", command=call_result).grid(row=3, column=0)

root.mainloop()
