The test modes "DTM" as specified by the Bluetooth
specification.

7.6.1. CMD_DTMSTART_REQ

This command restarts the module in direct test mode (DTM). When starting in DTM mode,
a CMD_GETSTATE_CNF message follows which indicates that the test mode has been enabled
successfully. Now the CMD_DTM_REQ can be used to start and stop various test modes.
Performing a reset will leave the DTM and restart the module in the ACTION_IDLE state.

7.6.2. CMD_DTM_REQ

to be stopped first before a next test can be run.
