Pairing Process failing - Error Code 7

    Hello, I'm running Windows 10 Home and have been using this software daily for the past few months. All of a sudden a couple days ago it stopped working. I unpaired the client computer to try and reset it, but on the server when I try to initiate pairing I am getting the following message:

    Failed to initiate pairing process. Please check the Bluetooth controller in your computer.
    Error Code: 7

    I haven't made any changes to either computer so I'm not sure what's going on. Also, I noticed in the days before it stopped working that the mouse started getting slow / choppy on the client computer. Not sure if that's related.

    Would love to get this back up and running, thanks!!

    Hi, Jeremy Mancini,

    Please let me know the hardware id (e.g., USB\VID_xxxx&PID_yyyy) of your BT adapter by following the below steps:

    1. Open Device Manager (Control Panel > Device Manager).
    2. Go to Bluetooth category and expand it by double-click, and choose the Bluetooth adapter, and then right-click it. From the popup menu, click "Properties".
    3. In the Properties dialog, click "Details"-tab, and choose "Hardware Ids" from "Property" combo-box. It will show the hardware id in the Value field.

    Thanks in advance.

    Hi Seungjin Lee,

    I tried running the trial version of the software (to see if it could be useful for me) and ran in the exact same problem. In my case my BT adapter has 2 hardware ids:


    Hope you could help me too, thanks

    I am experiencing the same problem on my laptop running Windows 10 Home (Version 10.0.17763 Build 17763).

    If it helps, I had the same problem a few weeks ago after installing Across v2.09. Since then, I have installed Across 2.11, but have the same issue.

    I am also experiencing the same issue trying to connect Lenovo Thinkpad to iPhone 8 on IOS 13.3.1

    My bluetooth hardware id is:

    I am trying to test out the trial version before paying for the paid version as this would be more useful than another bluetooth keyboard if I can get it to work.

    Across suddenly stopped working for me as well. I'm a paid user. Is there a workaround?

    Windows machine shows error code 7

    Custom built PC, BT adapter is usb stick.
    Adapter itself is working and can connect to my Note 10+ (at least transferring audio in Your Phone works and it require device to be paired).

    You don't have to install any accompanied software for your dongle (CSR chipset based) since Windows already has its driver.
    If you had installed them, please remove them and then retry.

    You don't have to install any accompanied software for your dongle (Broadcom chipset based) since Windows already has its driver.
    If you had installed them, please remove them and then retry.

    I just uninstalled, inc driver, plugged it back in, and get same error code 7 when trying to pair

    btw when i go to device manager / bluetooth i have several devices listed, even tho i only have the dongle, and no inbuilt bluetooth, idk if thats relevant but thought id mention it, the list looks like this;

    > bluetooth device (RFCOMM protocol TDI) - under properties says manufacturer microsoft and lociaction broadcom BCM20702 (which is my dongle)

    > bluetooth HID emulator - manufacturer clixon , location microsoft bluetooth enumerator

    > ... 4 more rows same as above...

    > broadcom BCM 2070 - which is my dongle

    > microsoft bluetooth enumerator - location broadcom dongle

    > microsoft bluetooth LE enumerator - location broadcom dongle

    is this normal to have so many devices appearing when i only have the dongle?

    wondered if they might be conflicting

    in addition to this error code 7 issue with my pc using dongle, i also have the issue with the pc using intel belutooth whereby its advertsiong keyboard but cant see it as an available device on the other pc

    Here is the screenshot for my dongle that is slightly different than yours in the dongle revision number.
    My dongle works fine without any error.

    Sorry. I have no idea.

    mine looks like yours in screenshot, so ok its not to do with that

    id just like to figure out if my error code 7 is due to a problem in my pc or some other configuration that i have, that i need to fix, before purchasing

    i can see others with error code 7 also in this thread, some of them were saying they were using trial version also, i dont see any resolution for most of those

    Hello, I am a long-time user who didn't install it on his new machine until now. Although I am able to add my iPad via the bluetooth screen in Windows, when I click "add" in the app I get error code 7. I followed the instructions above re Hardware Ids; what I see is BTH\MS_RFCOMM.

    I note that it seems the software attempted to install a "Bluetooth HID Emulator", but that this "device not started". Here are the details:

    Device BTHENUM\{308a4c5a-1f45-4e63-82a5-422fb8a881df}_LOCALMFG&0000\7&3434dca7&0&000000000000_00000000 had a problem starting.
    Driver Name: oem36.inf
    Class Guid: {e0cbf06c-cd8b-4647-bb8a-263b43f0f974}

    Hey, Daniel Wigdor,

    Thanks for your love to across. :)

    I am afraid your BT adapter might be from MediaTek or RealTek. Please refer to our reply from other user support request with the same problem.
    The user bought a TP-Link CSR USB dongle and fixed the problem.
    I hope it helps.

    I have this same issue, and did originally have a realtek adapter. Seeing this post, I bought a CSR adapter, but I continue to get the same error.

    Are you sure your PC has the only one enabled BT adapter? If your PC has a built-in BT adapter, you have to diable it in advance of using a BT dongle. If the BT dongle is the only one adapter in your PC, I have no idea. Sorry.
