Is it possible to receive data as non-root?

[aditi1prakash]

Current example scripts need root access, is it possible to connect and receive data as non-root?

If not, then why is root access required?

Hello @aditi1prakash,
Let's say no, unless some work to configure the Bluetooth stack. The following is what I've found on the Internet, but I've never tried it actually.

By default, on Linux, the Bluetooth protocol stack needs special privileges to interact with. These privileges are implemented through properties called "capabilities" (see man 7 capability for details), and the tool to assign capabilities is "setcap".

Since the Python version of the BlueSTSDK makes use of the bluepy library, it is the binary "bluepy-helper" that interacts with the Bluetooth protocol stack; hence, in case you want to do so, you should locate where it is installed and assign the proper capabilities to it. See also here.

Hi Davide,

Thanks for the inputs. I modified the capabilities of the bluepy-helper file.

After assigning the capabilities, the blue_st_sdk throws a 'ModuleNotFoundError' for Manager module.

The required capabilities are set for the bluepy-helper file.

Any thoughts on a fix/workaround would be helpful.

Regards,
Aditi Prakash

Hello @aditi1prakash,
Can you check the output of the following command, to see whether the SDK is there?

find / | grep blue_st_sdk

Thank you,
Davide
