篇七：树莓派zero w蓝牙网关

令狐鸣

大佬求助啊~

首先感谢一下,这个方法太好了,树莓派刚好换成虚拟机服务器一直用蓝牙usb距离不够,家里蓝牙设备失联好久.
用闲置的树莓派按步骤一切正常,ha完美读取蓝牙设备.

但是有个问题,不知道我的什么原因,不稳定,运行一段时间就报错停止,再打不开,必须重启树莓派才能.抽风时间不定.研究了下日志基本相同,求给看看可能是什么问题.

日志:

首先会报这些

Fatal error while executing worker command: BTLEManagementError
Traceback (most recent call last):
  File "gateway.py", line 91, in <module>
    raise e
  File "gateway.py", line 73, in <module>
    mqtt.publish(_WORKERS_QUEUE.get(timeout=10).execute())
  File "/opt/bt-mqtt-gateway/workers_manager.py", line 55, in execute
    messages = self._callback(*self._args)

然后是不同设备,每次不一样,感觉是刚好碰上那个就是哪个

File "/opt/bt-mqtt-gateway/workers/miscale.py", line 22, in status_update
    topic=self.format_topic("weight/kg"), payload=self._get_weight()
  File "/opt/bt-mqtt-gateway/workers/miscale.py", line 31, in _get_weight
    scanner.scan(self.SCAN_TIMEOUT, passive=True)

##########################
File "/opt/bt-mqtt-gateway/workers/btrssi.py", line 77, in status_update
    devices = scanner.scan(5.0)

之后基本又相同btle.py问题

File "/usr/local/lib/python3.7/dist-packages/bluepy/btle.py", line 854, in scan
    self.stop()
  File "/usr/local/lib/python3.7/dist-packages/bluepy/btle.py", line 803, in stop
    self._mgmtCmd(self._cmd()+"end")
  File "/usr/local/lib/python3.7/dist-packages/bluepy/btle.py", line 312, in _mgmtCmd
    raise BTLEManagementError("Failed to execute management command '%s'" % (cmd), rsp)
bluepy.btle.BTLEManagementError: Failed to execute management command 'pasvend'

python也不太懂,这个方法真是看到了希望.希望可以完美运用.

不知道是不是python或者Bluez版本问题.
用的3.7和5.5

自己的做的这个蓝牙网关可以连接米家所有的蓝牙设备嘛？例如绿米的蓝牙锁之类的？

接入小米电子称成功，有个BUG会导致服务自动终止。  >3000oml的这个测身体阻抗的经常超出设定值导致异常。在程序文件中给注释掉就好了。

一看就会，一试就废

楼主您好，如果蓝牙设备不在您这三项设备里，配置是要自己写吧？

你好大神按步骤执行python3 gateway.py  出现这种错误。麻烦问一下什么情况？C:\Users\MaNing\Desktop\微信截图_20200908143534.png

确实esp32更合适

ESP32的蓝牙信号太弱，隔一堵墙就基本收不到信号了，全屋蓝牙设备要接入估计要部署几个，这个树莓派不知颠倒信号如何

好详细教程，有个二代的派一直吃灰中，好像没什么用
