Hi，guys, It seems that I met a similar problem with Frank.
I use nRF52832 running HCI_UART sample as a controller. I want to make the controller advertise unconnectable packets outside， so I use bluez （version 5.48）
and hcitool to set advertise data :
sudo hcitool -i hci0 cmd 0x08 0x0008 1f 02 01 06 03 03 aa fe 17 16 aa fe 00 -10 00 01 02 03 04 05 06 07 08 09 0a 0b 0e 0f 00 00 00 00
and set advertise enable:
sudo hcitool -i hci0 cmd 0x08 0x000a 01
I detect the process with btmon, the controller returns success ,like this below:
But I didn't find the packet whose data was what I have set with hcitool command. I wonder if this is normal, and will the whole zero mac-address cause this problem ?
