Hi Luiz, thanks for answering, I checked: 1) Cache=always. I do not see differences executing bluetoothd without main.conf or running it with: bluetoothd -n -d -f main.conf (with Cache equal to "always") 2) the info/attributes files are being written in the device cache, no change, just the file dates are refreshed 3) the multiple Read Requests / Read by Group Requests are sent every time the device connects Is there another configuration apart from Cache that I can help here?
