[quote userid="77477" url="~/f/nordic-q-a/50135/issue-with-serial-program/200004"]the pins are not configured[/quote]

So configure them, then?

And the other things:

So what investigation and debugging have you done to find the problem?

What nRF52 board are you using?

Have you checked that there are no restrictions on using pins 25 & 26; eg, is anything else already connected to them?

Are you sure that you got Tx & Rx the correct way around?

Have you used an oscilloscope to see what's happening on the wires?
