Does Direct Test Mode v2.4.1 support SEGGER JLINK test

[hugh512]

My production board doesn't support UART, but we have SEEGER JLINK using RTT to debug with. I'm using nRF5_SDK_17.0.2_d674dde\examples\dtm\direct_test_mode project.

If I replace the UART with RTT, does Direct Test Mode v2.4.1 can test directly?

Hi Hugh,

It might be possible to send the DTM message through RTT if you send them one by one, but it might not be and easy route to take. It could work, but not a method to be recommended. 

The more pressing question is how are you plannign to do the BLE certification as the Bluetooth spec https://www.bluetooth.com/specifications/specs/core60-html/ requires you to have the UART pins available.

Best regards
