Hi Sunaina, 

Assuming you are running DTM from latest nRF Connect SDK, if you check the documentation for DTM sample, you will see that the nRF53 uses an experimental remmote HCI implementation. And if you are using custom board then make sure that you have selected right configuration for your board like in ncs\v3.0.2\nrf\samples\bluetooth\direct_test_mode\remote_hci\boards\nrf5340dk_nrf5340_cpuapp.overlay etc.
