Bluez core interferes with HCI socket commands

Question

I have following problem: I have created a HCI socket via pybluez and try to create a connection to a remote device. I send successfully a CREATE_CONNECTION command but after receiving the answers it seems the bluez stack sends further requests automatically like "Read Remote Supported Features".(visible in the wireshark traces of the HCI communication) I wanna have full and exclusive control over the bluetooth controller. I have also tried to stop the bluetooth service but the bluez stack still send automatically requests.

Any hints or tips how to solve this issue?

cheers

I was looking for the same thing and found the solution. Basically you need to bind your socket with the

hci_channel=HCI_USER_CHANNEL
