@Wassim_Qorvo,
I saw a comment from you on this post (Getting started with DWM3001CDKE - #8 by Wassim_Qorvo) stating that GPIO 1, 19 is the wakeup pin for DW3000. Does DWM3001CDK_C2 actually have an accessible wakeup pin? When I try to access 1, 19 I get the following on RTT.

The CS assert when I try to force the pins and read back their values appears to not show pin movement so it’s almost like my DW3000 won’t allow me to drive GPIO to wake it.
