Ss_twr responder Interrupt Version

Hi, I am working with the ss_twr examples from the github repo. I want to be able to make the ss_twr_resp function for responding use interrupts like the ss_twr_init_int example does, where some of the waiting while loops are replaced with interrupt handler variables. I have tried directly replacing the same code from the initiator to responder for interrupts, but they don’t seem to be working. Has anyone made a version of the responder code with interrupts? My end goal is to replace the interrupt variables with freertos semaphores, if that helps at all as well.
