see activity with -e, but not when I add -l

Hello, using a Dragontooth dongle passed through to an Ubuntu 22.04 VM. When I run sniff_receiver.py by itself, or with "-e", I see activity. But when I add "-l", I don't. Curious if anybody has experienced similar or knows the cause.

That’s normal. When you don’t specify -l, it listens using the 1M PHY. When you specify -l it listens using the coded PHY instead. Most devices use the 1M PHY rather than the coded PHY, so if nothing nearby is using the coded PHY you won’t see anything.
