我有一本关于ble继电器板的中文手册,其中似乎说明,为了激活继电器#1,发送的命令是:
C504作为前缀 密码部分为12345678 AA作为后缀
如何从python脚本发送此消息?我过去用过这个:
p = btle.Peripheral("bb:00:00:15:27:19")
s = p.getServiceByUUID("0000ffe0-0000-1000-8000-00805f9b34fb") #ffe0
c = s.getCharacteristics()[0]
c.write("e")
p.disconnect()
换一块不同的板。我知道bluepy代码很好,它只是我需要更改的命令
尝试此代码后:
password = '12345678'
response = c.write('\xC5\x04' + password + '\xAA', withResponse=True)
我得到这个错误:
Traceback (most recent call last):
File "1on.py", line 54, in <module>
letsgobaby()
File "1on.py", line 46, in letsgobaby
response = c.write('\xC5\x04' + password + '\xAA', withResponse=True)
File "/usr/local/lib/python2.7/dist-packages/bluepy/btle.py", line 168, in write
return self.peripheral.writeCharacteristic(self.valHandle, val, withResponse)
File "/usr/local/lib/python2.7/dist-packages/bluepy/btle.py", line 520, in writeCharacteristic
return self._getResp('wr')

resp = self._waitResp(wantType + ['ntfy', 'ind'], timeout)

raise BTLEException(BTLEException.DISCONNECTED, "Device disconnected")
bluepy.btle.BTLEException: Device disconnected
我可以建议您将输出更改为以下内容:
这样,它将根据该文档发送适当的值
