It looks like the Bose Soundlink Bluetooth Speaker only uses Bluetooth tether to connect to devices. Could you tell me a little more about what is happening?
Is the error message you mentioned an audio message or a notification?
If it's a notification, is it from coming from the Bose Connect app or the Pandora app?
If it's the Pandora app, can you let me know what steps you've taken when you receive the message?
Are you able to take a screenshot of the error message to share with me?
Can you also let me know the make and model of the device you're using to connect to the speaker, and the Pandora version? Let me know if you need help finding that.
