How to perform DTM test on nRF5340

[xiating]

Hi,

We did not find any DTM test code for nRF5340? How can we evaluate the radio performance? 

Thanks,

Hi,

Unfortunately our standalone DTM and radio test examples are yet to be ported to nRF523 series. However it is possible to get DTM support for radio evaluation through zephyr: nWP029 - Zephyr Bluetooth Low Energy Controller

"The Controller has Bluetooth Low Energy Direct Test Mode (DTM) built in, which makes production testing and RF PHY re-evaluation easy. It supports all mandatory and optional DTM features over an HCI transport. "

Unfortunately I have not tested this with NCS so not really sure how to enable it at the moment.

Hi,

Can DTM now be built for NRF5340pdk ?

With 1.4.2 SDK I always get compilation error "unknown type name 'NRF_RADIO_Type'". Maybe I'm doing something wrong, but other examples are compiled without issues.

Best regards,

Alexey
