pcap file with zero bytes

[milanmilenkovic]

I installed btlejack on a raspberry pi 3 using a micro:bit connected to it. Sniffing a connection works well but trying to export the sniff to a file does not work. It always creates the file with zero bytes.

• The command i use is:

btlejack -x pcap -o test.pcap -c <mac_add>

I also tried all -x options and I got the same issue. Also if the -x and -o options are passed after the MAC address it is same behaviour.

Does btlejack capture a BTLE connection ? Do you see some packets displayed by btlejack when you connect to your BTLE device ?
