Cannot get Log file as i do not have Root permissions.

Hi @Lann4daze, using the HCI Bluetooth interface typically requires running as root, else you will experience permission errors as you observe in the console log you provided. If you don't have root permissions, you won't be able to run pi-suite-hci but rather only pi-suite (which you can test to confirm that the error is due to lack of HCI permissions).

Kindly close the issue if the root cause is lack of root permissions (no pun intended). Thanks and have a happy and safe New Year!
