Hi there! I'm trying to use this branch to get my NRF51 dongle to work with Python3.7, have you managed to do something similar?

Currently with the heart_rate_collector example, i'm hitting the following:

  File ".\heart_rate_collector.py", line 187, in <module>
    main(serial_port)
  File ".\heart_rate_collector.py", line 151, in main
    conn_handle = collector.connect_and_discover()
  File ".\heart_rate_collector.py", line 92, in connect_and_discover
    self.adapter.service_discovery(new_conn)
  File "C:\Users\XXX\AppData\Roaming\Python\Python37\site-packages\wrapt\wrappers.py", line 562, in __call__
    args, kwargs)
  File "C:\Python37\lib\site-packages\pc_ble_driver_py\ble_driver.py", line 124, in wrapper
    raise NordicSemiException('Failed to {}. Error code: {}'.format(wrapped.__name__, err_code), error_code=err_code)
pc_ble_driver_py.exceptions.NordicSemiException: Failed to service_discovery. Error code: BLEGattStatusCode.invalid_handle

It appears that the handles that come back are really strange (and typically large) numbers, instead of 2,4,6... that I get with the pip package and Python 2.7. On our actual development code, if I request a characteristic handle I know is present, I get a Python list of the first two characters in ASCII, then a load of incorrect garbage afterwards also.

Any tips/guesses on what I could be doing wrong?

Cheers!
