Hi Brennan, Looking through the code, I am guessing you hacked up net/bluetooth/hci_request.c::active_scan to set enable_cp.filter_dup = 0? How did that turn out? Was there a lot of volume? I am running 'hcitool lescan --duplicates' with a couple of cc2650 tags I have (one custom fw) and see about 20-25 adv/second. That doesn't seem so bad. What type of numbers did you see?
