Python SDK - metawear board initialization parameters

in Documentation & Tutorials

In the C++ documentation the function "libmetawear.mbl_mw_metawearboard_initialize" has three parameters and in the test.py has two parameters.
When I'm trying to execute the test.py example (using Python SDK), I'm getting error message below:

root@debian:/home/user/Downloads/MetaWear-SDK-Python# python test.py XX:XX:XX:XX:XX:XX
error 1537656591.703993: Error on line: 296 (src/blestatemachine.cc): Operation now in progress

Traceback (most recent call last):
File "test.py", line 17, in <module>
libmetawear.mbl_mw_metawearboard_initialize(device.board, init_handler)
TypeError: this function takes at least 3 arguments (2 given)

Why the function has only two parameters here?

Thanks

    Just for explanation what I'm trying to do with Python-SDK. I want to:
    1. connect to multiple boards and get data from multiple sensors
    2. I want to start logging at all boards at once and
    - 2.1. pause logging
    - 2.2. resume logging
    - 2.3. pause logging
    - 2.4. resume logging
    - 2.5. pause logging
    - 2.6. resume logging
    3. stop logging
    4. Then I want to download the raw data in my computer.

    Using the multi_device.py example I was able to connect to multiple sensors, stream accelerometer data only and save the data in realtime in .csv and .txt format (haven't paused and resumed the streaming yet).
    As I mentioned above, I need this in logging mode and therefore something to start with.
    Any help or example on logging in python will be highly appreciated.

    Thanks

    Actually will open new thread topic re. logging with python as I think does not belong here.

    Use the scripts in the examples folder.

    The test.py file is out of date and will be removed; it does the same thing as multi_device.py.
