Bluetooth LE with data length extension (DLE) seen as [bad mic]

edit

I'm trying to get a setup I have to work. I'm capturing encrypted bluetooth LE connection, which uses DLE (packet size bigger than 23 bytes). packets which are smaller than 23 bytes are dencrypted and parsed correctly, bigger packets are not parsed correctly and seed as "bad mic".

The problem could either lay on the sniffer (nordic nRF52840 DK) or I might be missing a wireshark plugin. I'm currently using wireshark 2.6.4 (also tried 3.0.4).

1. Does wireshark support DLE out of the box? (I saw ATT supported up to core 4.0 so I am concerned that is an issue). I did see a screen shot of DLE work on wireshark on another site so I'm sure this could work.
2. If anyone can provide a small trace with DLE working so I can confirm if there is an issue with the sniffer or my wireshark this could be super awesome. really appreciate your help
