NRF52805 DTM setup reset command failed

I  using nrf52805 for DTM, in sdk17.1, pca10040e. I only changed RXTX  pin number, but did not modify the rest.
Then use Nordic Connect for DTM testing, and the following prompt appears:

 how to use the DTM routine on 52805?

Another question is whether DTM does not require burning the protocol stack, only the routines need to be burned
