NRF52805 DTM setup reset command failed

[zhangchenfang]

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

Hi,

 

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

DTM does not require the SoftDevice, as it uses the radio peripheral directly.

 

how to use the DTM routine on 52805？

It should be to select the wanted GPIOs for TXD/RXD, and then flash. Which GPIOs are you using?

 

Kind regards,

Håkon
