Hi! I'm trying to create a bridge between BLE advertisements and the web for sensor data logging. The BLE advertisements use manufacturer data to transmit the sensor data. I'm running on a Raspberry Pi 3b. I've been trying to use the Bluez dbus interface with DuplicateData, trying both true and false, and I never seem to get duplicates back. I dug into it via hcidump and noticed that the scan enable still has filter duplicates set to true regardless. I can only manage to get it set to False when using hcitool. I believe I've tracked the issue down into the kernel here: https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/tree/net/bluetooth/hci_request.c#n858 where enabling duplicate filtering is hardcoded. It seems that hcitool side steps this by talking directly to the hci device. Could someone confirm I'm on the right track? I'd be willing to plumb the DuplicateData value through to the kernel if someone could help me find the call path down. Thanks! ~Scott
