Switch Anchor into BLE Central Device

Hi, I would like to switch the anchors in my network into BLE central devices instead of peripherals, so that they can receive advertising packets. How would I go about doing this? I would still like to use PANS and it’s ranging protocols and all of that, but I think I would have to edit “softdevice” or something, but I am not sure where to do that, starting with the dwm-simple code provided. Thanks!
