Characteristic without write-without-response property

[jedras1991]

Hello,
my BT module which is Bluno nano does not have write-without-response property , instead it has write property.

Connecting gives me this error:

Is it still possible to connect with this device?

Changed self.write_char = self.find_char(write_uuid, 'write-without-response') to self.write_char = self.find_char(write_uuid, 'write') in ble_interface.py and it worked!

Very nice, thanks for looking into it and trying it out.
I will soon improve the characteristic detection/handling (#28) and also take the write property into account.

I have just released v2.1.0 that works with both write and write-without-response!
