RE: pc-ble-driver-py: what is sys.argv and how to define it?

Hi,

sys.argv is, simply put, the list of command line arguments that was provided when running the python script from the command line.

So what it means is that if you run it with e.g. "python heart_rate_collector.py" from the command line, then you need to change that to "python heart_rate_collector.py NRF52", where NRF52 is then command line argument 1 to the script. (Argument 0 is the name of the script itself.) You can also, optionally, provide the serial port (for the connectivity device) as command line argument 2.
