This is a limitation of the current PCAP packet format for BLE RF. It currently provides no means to indicate the direction. Iām working on improving the packet format together with other users of it so that the PCAP can include information about direction, PHY, and some BLE 5 related aspects. https://code.wireshark.org/review/#/c/37142/

The pcap_new branch labels the PHY in use, and indicates direction for data packets using the revised DLT/LINKTYPE spec here: https://gistcdn.githack.com/sultanqasim/8b6561309f5934f084a0d938ae733b7a/raw/c9172a730117c824a1b80add472052220810e538/LINKTYPE_BLUETOOTH_LE_LL_WITH_PHDR.html
I'm working with the tcpdump.org folks to make this spec update official. After that, the relevant Wireshark change can be merged.
