Bluetooth connection problem.


Dec 10, 2020
Hi Guys, I have a problem with connecting my car diagnostic tool with my REDMI Note 9 Pro phone.
Minimum requirements for the phone are: Android 4.3 or higher and Bluetooth V4.0. My phone obviously meet that criteria. Just to add - I have no problem connecting this tool to my old Samsung tablet via Bluetooth (lower spec tablet).
I have contacted diagnostic tool manufacturer and they informed me that my phone might have an issue with 'Bluetooth Smart Stack'. I have no idea what it means... do you know if there are any solutions to this issue? Or is there an app or setting change to solve this problem?
Regards, Adam.
