我有一段代码,我想用bluepy将十进制值1从python脚本写入一个可编程设备:
#!/usr/bin/env python
import bluepy.btle as btle
print ("outside")
def letsgobaby():
print ("turning1on")
p = btle.Peripheral("bb:00:00:15:27:19") #zl-rc04a
# GET SERVICES
services=p.getServices()
for service in services:
print service
# NORMAL get to write to ...
s = p.getServiceByUUID("0000ffe0-0000-1000-8000-00805f9b34fb") #ffe0
c = s.getCharacteristics()[0]
#1 is relay1on, 2 is relay1off
c.write(1)
p.disconnect()
if __name__ == "__main__":
letsgobaby()
但我有个错误:
pi@raspberrypi:~/Documents/python/failedPythonBLE $ python 1on.py
outside
turning1on
Hallo from Peripheral
