linux - Intercept a bluetooth communication between two devices -

i ideally able watch 2 bluetooth devices communicate , see sent between them.

now know isn't possible mitm bluetooth directly, in theory don't need since pair both devices linux pc in theory, , luck there way linux pc relay comms between two.

i'm trying reverse engineer specific command between device , ios app , seems logical approach. googling isn't giving me pointers on however. know wireshark sniff data pc -> device, need ios -> pc -> device.
