在iOS App和Raspberry Pi BLE之间进行通信

Question

我正在使用BLE应用与Raspberry Pi 3通讯。使用iOS应用，我想发送信号，而树莓必须接收信号。 Python代码正在等待通知。

关于iOS应用程序和Raspberry Pi的各个方面，我都有几篇文章，但没有一篇可以一起工作。

iOS代码：

@IBAction func ButtonSet1 (_ sender: Any) {         // Button defenition SET

        let string = "1"

        let data = string.data(using: String.Encoding.utf8)

        let characteristic = servoCharacteristic
        //get right on out of _characteristics! array
        _peripheral?.writeValue((data)!, for: characteristic!, type: CBCharacteristicWriteType.withResponse)


        print(data!)
    }

Python 3代码：

from bluepy import btle

class MyDelegate(btle.DefaultDelegate):
    def __init__(self):
        btle.DefaultDelegate.__init__(self)

    def handleNotification(self, cHandle, data):
        print("A notification was received: %s" %data)

p = btle.Peripheral("44:00:10:28:63:ac")
p.setDelegate( MyDelegate() )

# Setup to turn notifications on, e.g.
svc = p.getServiceByUUID("d0611e78-bbb4-4591-a5f8-487910ae4366")
ch = svc.getCharacteristics()[0]
print('ch.valHandle')


while True:

    p.waitForNotifications(1)
        # handleNotification() was called

    if p==1:
        print('1')

    else:
        print('0')

    pass

p.disconnect()

在双方，我都没有任何错误，但是他们彼此之间没有沟通。
