dbus_api, need help with profile implementation

[priyankguddu]

Hi,
Thanks for writing a clean API for bluez python dbus with GATT profiles. I was using the library and things are good for Genric services and Device information services, but when I implement vender specific services from which the data need to be extracted
LegacyPairing: no
UUID: Generic Access Profile (00001800-0000-1000-8000-00805f9b34fb)
UUID: Device Information (0000180a-0000-1000-8000-00805f9b34fb)
UUID: Vendor specific (46a970e0-0d5f-11e2-8b5e-0002a5d5c51b)

I did following:
a) I created a python file in profiles folder with the uuid mentioned in vendor specific. I made the service class and then it detect the device.

Issues:
a) How to get the characteristics, like in service (using d-feet) I see 2 characteristics (char0017 & char 001a) corresponding to my device services, so how to identify them uniquely as different charachterstics
b) Startnotify and stopnotify methods API, how to use that cleanly, i.e I see in some example u have set .notifying = True in service rather than characteristics.
c) I see some methods like notifyx which can take callback and error back, how to use thos

I must say, its a great wrapper for direct using bluez, and if some good examples to use a new device specifically how to register a callback function on notify and how to set some raw values would be helpful.
I am meanwhile understanding other aspects in the code.

Thanks for help
