Fast and slow advertising

[AbbyD]

I would like to calculate how much time my device does fast advertise and how much time it does slow advertising?

Is there a way to check this in python script?

The most complete solution would be to use the nRF sniffer and the python API that comes with the sniffer to count the advertisement packets and then deciding the time spent in fast and slow advertising.
The other alternative is to turn on logging on the UART for the DK for the code (all nRF5 SDK examples include logging)  and then read the log messages on the PC using python and then using the log messages to decide when the code is in fast advertising and slow advertising.
