我完全按照文档中提到的所有步骤进行操作。我在 Raspberry Pi 3 以及运行 RASPBIAN STRETCH LITE（内核版本：4.9）的 Raspberry Pi Zero W 上进行了尝试。我还尝试使用 Python 2.7.13 和 Python 3.4.3 构建/运行它，但是在运行任何示例脚本时我总是遇到同样的错误。在修复了与缺少库相关的一些问题后，make 和 make 安装运行良好。我什至在全新安装的 Raspbian Stretch Lite 上尝试过这个，同样的错误。我尝试在bitbucket上寻求解决方案，但似乎还有其他人发布了相同的问题并且没有答案。我在另一个窗口中运行了 hcidump，我可以看到发生了一些连接，但是又出现了这个错误

这是运行 hcidump 的结果

我正在运行的示例代码（连接）是这样的
from __future__ import print_function
import sys
from gattlib import GATTRequester
class JustConnect(object):
def __init__(self, address):
self.requester = GATTRequester(address, False)
self.connect()
def connect(self):
print("Connecting...", end=' ')
sys.stdout.flush()
self.requester.connect(True)
print("OK!")
if __name__ == '__main__':
if len(sys.argv) < 2:
print("Usage: {} <addr>".format(sys.argv[0]))
sys.exit(1)
JustConnect(sys.argv[1])
print("Done.")
甚至其他脚本似乎也表现出相同的行为
我刚刚做了一个 gdb 回溯，结果如下
