Hello,

Capturing SMP packets should be no different from capturing other packets on the link. Are you sure there are any SMP exchanges in the connection you’re capturing? There won’t be any if the link is being secured using existing keys. Perhaps you could share a sniffer trace that has this issue here?

Best regards,

Vidar
