x220 WWAN Upgrade: Bluetooth addition?I

I just swapped out the Intel 6300 wireless N card from my old x220 laptop for the new intel 7260 AC + bluetooth card. With a whitelist-removed bios and TPM set to inactive, I didn't have any issues getting the wireless to work at the rated speeds. My issue is that I cannot figure out how to get the bluetooth to work. I've installed the intel BT drivers, but it does not show up with FN+F5 or in the task bar. I have bluetooth enabled from bios.

Is there a separate whitelist for bluetooth devices? Does bluetooth not work when integrated into wireless cards? (e.g., do I need one of the extra BT addon cards?).

 

please see this,

had the same issue until I taped pin 20. Good luck

 

Interesting, that would not have been in my list of troubleshooting steps. I'll try that and report back. It sounds like it would be the same issue.

 

Guess I'm out of luck on this one, I've only got 1 full size slot which is for WWAN or mSATA and the mini size for wireless. I'm already using the full height for my mSATA drive and I don't think the tradeoff is worth it for bluetooth. Thanks for the help anyway though!

 

Hey all -

Same situation here. Except I had the factory Bluetooth module installed. I had to disable the BT 4.0 on the AC7260 card in Device Manager so the internal BT that came with the X220 kept working.

So, I tried taking the internal BT daughter card out and thinking I could just enable the BT 4.0 on the AC7260 in Windows 7. Nope. Once I took the internal BT daughter card out, the Bluetooth light didn't want to come back on when I rebooted, NOR did Bluetooth show up in FN-F5. However, the BT light DID light until Windows started loading. And yes, it also disappeared from Device Manager, even in a disabled state (like something was turning the Bluetooth hardware switch off.)

I did a little research, and there's this "rfkill" program for Linux that controls the "ACPI hardware switches" to turn things like Bluetooth and Wireless on and off in Linux (much like the FN-F5 does in Windows with the little Lenovo utility). Does anyone know a way around the FN-F5 program in Windows or a substitute to RFKill in Windows that can do the same thing? The FN-F5 driver, or another driver on the Windows system is turning the "bluetooth hardware switch" off. That's why it's not even showing up in Device Manager anymore to even enable the 7260's BT 4.0.

I'm going to try booting up in Puppy Linux and using RFKill to see if I can even get the BT light to come on.. if I can, there's something in Windows that's shutting the thing off. If we can work around that, we can get Bluetooth to work.

Edit: RFKill docs: rfkill - Linux Wireless

 

My experience of this is slightly different.

I recently installed the Intel AC-7260 adapter in my X220 to take advantage of 802.11ac wireless (running Windows 7 Pro 64bit, modded BIOS).

The AC-7260 is supported by the latest Intel PROSet drivers already on my X220, but the Bluetooth 4.0 wasn't detected.

However, this was solved by downloading and installing the following PROSet/Wireless Software for Bluetooth from the Lenovo site:

Once installed, the built-in Bluetooth produced an error in Device Manager. Trying to install the ThinkPad Bluetooth drivers failed, and subsequent messing about resulted in one or the other Bluetooth adapters working.

However, to my astonishment (perhaps an overstatement), Fn+F5 still turns on and off the Intel Bluetooth adapter, but the errors in Device Manager were obviously a frustration to someone who likes a tidy ThinkPad.

My next thought was to physically remove the stock ThinkPad Bluetooth adapter. Again the ThinkPad booted OK, but this time there was no Bluetooth option in the Fn+F5 menu. Refitting the stock adapter brought the Fn+F5 Bluetooth option back (albeit with some judicious use of System Restore to revive the Intel adapter which didn't appear to like reinstalling it).

Next step is to experimenting by installing Windows 7 from scratch with the stock ThinkPad Bluetooth adapter removed just to see if that will enable Fn-F5 with only the AC-7260 adapter installed (potentially a long shot, I know).
