Would be nice if this behaviour was fixed in the next version. Here's a patch that fixes the problem:ĭiff -git a/SnifferAPI/Filelock.py b/SnifferAPI/Filelock.py of Wireshark will be demonstrated for a computer running Mac OS X 10.5.8. TypeError: expected str, bytes or os.PathLike object, not NoneTypeĬalling os.path.basename(None) results in an unhandled exception before find_sniffer() in UART.py gets to the correct device. mode that Wireshark allows, the network interface does not care if the.

I'm using nrf_sniffer_for_bluetooth_le_4.0.0 on Ubuntu 20.04.3 and running `./nrf_sniffer_ble.py -extcap-interfaces` fails on my system.
