使用c编程连接蓝牙设备

Question

我想将用于将蓝牙设备连接到Raspberry pi的python代码转换为C代码。有可能吗？？有没有一种方法可以使用c编程将蓝牙设备连接到树莓pi。代码如下：

import pygatt
from binascii import hexlify
import time
adapter = pygatt.GATTToolBackend()
def handle_data(handle, value):
"""
handle -- integer, characteristic read handle the data was received on
value -- bytearray, the data returned in the notification
"""
print("Received data: %s" % hexlify(value))
try:
adapter.start()
device = adapter.connect('AC:23:3F:AA:36:7C')
device.subscribe("7f280002-8204-f393-e0a9-e50e24dcca9e",
callback=handle_data)
# The subscription runs on a background thread. You must stop this main
# thread from exiting, otherwise you will not receive any messages, and
# the program will exit. Sleeping in a while loop like this is a simple
# solution that won't eat up unnecessary CPU, but there are many other
# ways to handle this in more complicated program. Multi-threaded
# programming is outside the scope of this README.
while True:
time.sleep(10)
finally:
adapter.stop()

我知道的两个选项：https://github.com/petzval/btferret和https://github.com/weliem/bluez_inc.这是等效的bt雪貂代码。

/********* DEVICES.TXT file ************

DEVICE = LE device     TYPE=LE      NODE=7   ADDRESS = AC:23:3F:AA:36:7C
