HI
I am planning to test it by linking the DTM of nRF Connect For Desktop.
However, I am contacting you because the DTM does not work.
The nRF52-DK board operates normally, but an error occurs on the homemade PCB.
But the strange thing is that this PCB also ran DTM well, but when I tried it again at some point, it didn't work.
.
.
1) In the example, DTM was downloaded to the target board.
.
2) When running the latest version 2.4.1 of DTM, the following error occurs for the first time.
