Bluetooth 4.0/BLE/Bluetooth Low Energy devices support on Windows 7.

[Sirios]

Hello,

I have Lenovo X220 laptop (7 x64 Ultimate) with Bluetooth 4.0 (BCM20702A0), it is not a USB dongle, but a unit that is placed in special socket under palmrest of the laptop.

Issue is I am not able to pair any BLE devices to it in Windows 7. I have googled and found out that Windows 7 do not have native support for BLE and connectivity can be achieved with a proper Bluetooth Stack. I have tried Windows 10 and I can find and pair BLE devices there, but Win10 do not support all software for X220 that I need, so I am stuck with Win7.

Is there a way to make BCM20702A0 provide connectivity for BLE devices?

Hello,

according to Lenovo the X220 has Bluetooth 3.0.

Where did you see that your ThinkPad is using BCM20702A0?

The Windows 7 (Broadcom ThinkPad Bluetooth) compatible device drivers are here on the Microsoft Update Catalog. You can manually download these, if you did not receive one via Windows Update.

It was written on the BT daughter card that I put into X220 instead of BT 3.0 it had, and the same data was reported by Device manager.

So instead, buy a USB IOGear Bluetooth adapter. If Windows 7 can't do BT 4, then you're a little stuck.

Alright, so I have installed the BT4.0 Bluetooth Stack + drivers for Windows7 from Lenovo Support site, now my device can see and "connect" to BLE devices, but when it comes to installing drivers for the connected device (two different BLE keyboards in my case, can see and keyboard connection password pop-up appears), 1 of 3 drivers installation fails for some reason: Windows reports that cannot find 1 of 3 drivers for keyboard (no matter which one of 2 I use - all two different brands).

I honestly don't know the answer. Bluetooth can be tricky.

So here is what I have now: I have installed Lenovo Bluetooth 4.0 Stack, but during pairing BLE keyboards (two different brands) I have 1 of 3 drivers fail to install.

Upon driver installation fail, I have this report in Device Manager:

Any help would be much appreciated.
