In the rarest of rare case that you’ve picked up a Blackberry and are having trouble pairing it with a Bluetooth headset, this should help you out.
My Blackberry, out of the box, would pair with my handsfree kit (in this case, my car’s built-in bluetooth kit) to attend calls. If I disconnect the bluetooth connection, and try connecting it again, the Blackberry would display ‘Connection to … failed’ and the car’s display would pop up a ‘Pairing failed’ message.
I couldn’t be the only possible user facing this issue and surely, RIM wouldn’t make phones that wouldn’t pair successfully with a Bluetooth handsfree kit. So, I started the standard process of hitting my favourite search engine, keying in various combinations of words to figure out what could have been wrong. Many helped point me in the right direction, but at least the first page of results didn’t get me anywhere near what I’d hoped for. Many posts speak about ‘Bluetooth profile’ mismatch and correcting it. I understood what it meant, but those posts didn’t clearly speak of an option which will allow me to get this corrected.
So here’s what you need to do to get this to work – Navigate to Options -> Network & Connections -> Bluetooth Connections. Press the Blackberry key to bring up the menu, and select Options. It may be worth noting that it doesn’t matter whether your Bluetooth is ON or OFF. Scroll down to ‘Services’, and keep these two checked:
Uncheck the following:
Serial Port Profile (and all sub-options under this)
A/V Remote Control Target
I should mention that the last two we are unchecking above will disable the ability of your mobile to play songs and be controlled with a Bluetooth device with those capabilities. In case you need those two, keep them checked.
Save the settings, go back to the Bluetooth Connections menu, delete the device you have added and force pairing again.
This has worked for me – let me know if it doesn’t work for you in the comments. The rest of this post is just what I think of the entire thing, and if you aren’t interested, you can consider the article complete.
From what I can understand out of this little exercise, it appears that the Blackberry attempts to use the enabled profiles to connect with the Bluetooth device, which shouldn’t be the case. From my understanding, most other phones do not do this and use the Bluetooth device’s profile to connect. I’m no expert in Bluetooth or have knowledge of how devices work, so feel free to correct me if I’m wrong.
Either way, in my opinion, this makes for very bad user experience. Considering most ‘normal’ users would never need Serial Port Profile, Dial-up Networking – these should have been disabled by default.
