org.kde.bluez: PendingCall Error: "Protocol not available"

Expected Result:

Some form of happy path user bluetooth pairing experience

so the bluetooth feature in dash - at least for now - will only connect, not pair

reason for that being is there's that whole authentication bit I just couldn't figure out how to do lol

oh...I thought I had paired before. It's always been this way?

robert5974 commented 3 years ago

@kylegordon did you try to pair the device in the OS first? That works for me and I believe was stated in the Readme. At least at some point it was if it's not there now. I would have to look. After pairing using the OS, dash will connect easily.

I am working with the Bluetooth service in Dash to see if I can inject pairing Bluetooth devices using the Bluez agent

@robert5974 last I looked into it, the appropriate bindings weren't implemented for pairing - I'd be interested to learn more about what you're looking into, I have a couple of personal projects that could benefit from pairing support.

robert5974 commented 3 years ago

Right, like @rsjudka said above, it only connects and does not pair so I have been researching and working towards implementing using the agent to authenticate device.

I was going to begin with a "no pin" authentication for pairing to test functionality. Adding the pin should be easy after proving that works. To use a "No pin" authentication method is called the "NoInputNoOutput" option when using the Bluez agent.
