[abbiy]

Hi, please its urgent so when i try to perform Knob attack everytime i get the same issue i.e.,

[] Found multiple adb devices [] Connected to 035be4a421519e6f [!] _sendThreadFunc: No response from the firmware. [!] sendHciCommand: waiting for response timed out! [!] initialize_fimware: Failed to send a HCI command to the Bluetooth driver. adb: Check if you installed a custom bluetooth.default.so properly on your Android device. bluetooth.default.so must contain the string 'hci_inject'. hci: You might have insufficient permissions to send this type of command. [!] connect: Failed to initialize firmware!

I do not know how to resolve it. My setup :- I am Using Nexus5 rooted phone with Lineage14.1 os install. I also copy paste the Bluetooth.default.so file into /system/lib/hw directory. I followed the same steps given in the nexus5 folder.
