https://devzone.nordicsemi.com/f/nordic-q-a/93063/bluetooth-doesn-t-work-on-nrf52832-while-debuggingHi! We&#39;re working on a development project using nRF52832. Our original prototyping PCBs used the nRF52832-QFAA. On these boards, the nRF worked without issues, and we could debug while using BLE even with multiple connections. We later moved on toen-USTelligent Community 13Fri, 21 Oct 2022 10:35:18 GMThttps://devzone.nordicsemi.com/thread/391837?ContentTypeID=1Fri, 21 Oct 2022 10:35:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0da10139-1aad-4723-927b-2bc77b11bba0Susheel Nuguru<p>Hi,</p> <p>It looks like it is the issue with our custom board design. It seems like the debug clock is causing noise on the radio output. We have seen this before and most of the times ended up as the board design/layout issue. I do not think that the change&nbsp;<span>NRF52832-CIAA-R alone has anything to do with behavior. Please double check in your board layout to see if the debug pins (SWD_XXX) are leaking noise to nearby pins/layers.</span></p><div style="clear:both;"></div>
