Gents, Thanks so much! Using it for a day, I find wireshark very useful and educational, knowing the API is fully capable for all wireshark functions, I will revisit the APIs for automation and production use. Thanks again!

The nRF sniffer for Bluetooth LE wireshark external capture (nrf_sniffer_ble.py)
uses the Python API to send all data to Wireshark through the external capture (extcap) interface.
So anything wireshark is able to do, you should be able to do with the Python API.
However using wireshark would of course be much easier, since all of the analysis is implemented there.

We don't unfortunately have much of documentation for the python API. I suggest to use nrf_sniffer_ble.py as your best example on how to use the python API.
Further description on how the packet could be analysed you could have a look here:
https://github.com/wireshark/wireshark/blob/master-3.2/epan/dissectors/packet-nordic_ble.c#L13-L131
Also in the release zip under the doc folder there is sniffer_uart_protocol.xlsx describing this protocol format in full.

Any feedback, suggestion for improvements, or actual changes to the python code would be very welcome.

I always use wireshark, which provide a nice abstraction and details for debugging a connection. The log file from wireshark can easily be uploaded here for other to take a look when there are any issues. I can check if someone can comment on your question about python documentation.
