Hi,
For troubleshooting purposes I need to execute only:
LE Create Connection
command and no other.
The d-bus interface doesn't provide this low level
functionality so I resulted to htctool.
The command translates to:
sudo hcitool -i hci1 cmd 08 000d 60 00 60 00 00 01 C2 49 C4 72 88 E0
00 18 00 28 00 00 00 2a 00 00 00 00 00
Which results in a correct command but triggers a
LE Read Remote Used Features
which is exactly what I want to avoid.
How to prevent the triggering?
