scanning or advertising stops when RTT enabled output via JLink

[Lucas.Yang]

When I set NRF_LOG_ENABLED true, the RTT log can be output without any problem, however, the scanning or advertising activity stop immediately.

I found there is something conflicted between softdevice and RTT.

How can I sovle the issue? 

Look forward to seeing who can help me...

Thinks a lot!

Hi

What project(s) are you seeing this issue in? Can you describe how I can reproduce this on my end? Have you made any other modifications than setting NRF_LOG_ENABLED to true in your application for the advertising/scanning to stop?

Best regards,

Simon

Dear sir,

 I found the issue comes from the bad PCB layout, for the SWIO and SWCK wires are going under the crystal， EMC-induced error maybe.

 Thanks for your kindly reply!
