Should have more example and usecase?

[NSLog0]

Hi, i'm a new with bluepy and BLE by python. I want to share my experience in 2 days of work with bluepy and request about update Docs

I found some method not written in the Docs and Docs are unclear. I tried to retrieve data from service and characteristics like

with code

rom bluepy.btle import DefaultDelegate, Peripheral

class NotificationDelegate(DefaultDelegate):
    def __init__(self):
        DefaultDelegate.__init__(self)

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

p = Peripheral("UUID", "public")

p.setDelegate( NotificationDelegate() )

svc = p.getServiceByUUID("uuid_service")
ch = svc.getCharacteristics("uuid_char")[0]
p.writeCharacteristic(ch.valHandle + 1, "\x01\x00", withResponse=True)

while True:
    if p.waitForNotifications(1.0):
        # handleNotification() was called
        continue

    print("Waiting...")
    # Perhaps do something else here

p.disconnect()

which I complete its by open stackoverflow, finally I got

Waiting...
A notification was received: ��R��R��S �
A notification was received: ��R��R��S��

still not clear with ��R��R��S �

It would be nice if you can update Docs , more example and usecase

About the notifications: it's all binary, like here [1]. You cannot just print it and expect something readable. Example of parsing it [2]. Another pair (spec & code) for speed & cadence [3] [4]. The examples might not work with python3 due to different handling of strings/bytes!

Thank your for your answer very helpful especially the 3rd . Anyway, I've done with how to get a data already and it's in the phrase for design classes and application structure
