Title: Bluetooth not connection to mobile
Post by: cpeterm on November 16, 2019, 02:48:42 AM
HP Probook 450 G0 Win 7 (64)
Bluetooth (BT) worked and I had mobile and speakers linked. Picked up a problem and I unfortunately deleted these 2 devices (control panel > devices) and wanted to ADD them again to fix the problem.  Since then cant ADD the previous ‘deleted’ THE PREVIOUS DELETED devices although they are discoverable. ADD searches and finds nothing. BT icon showing bottom right – click devices and shows noting. Clicked add device and nothing. Ran troubleshoots and checked ‘all BT drivers (device manager) but working properly and have up to date drivers. Restarted.
Device manager: Under ‘Bluetooth Radio’s’ I have -Microsoft BT enumerator and  -Ralink BT 4.0 adapter. Under ‘Network Adapters’ I have -Bluetooth device (personal area network); -Bluetooth device (rfcomm protocol tdi); -microsoft virtual wifi miniport adapter; -Ralink RT3290 802.11bgn wifi adapter; -Realtek PCIe GBE family controller.      THANKS

Have you tried disabling and re-enabling Bluetooth?
Or have you tried a spare device or headphones to test to see if it works at all?

What model were the speakers? What phone was it?

Ive noticed Bluetooth is a pain sometimes to get to work right on Windows 7, espically with iOS devices, you may just have to try a few more times.

Also, you may have to make the laptop's Bluetooth discoverable. Sometimes its discoverable on the devices but not the laptop itself. Maybe your Bluetooth settings need to be changed on the phone to make it visible for more than a certain amount of time, same goes for the laptop. (Maybe not the speakers, since its speakers. Not quite able to do that on speakers.)

In my experience, Android and headphones (Usually) seem to have no issues connecting to bluetooth on Windows 7, but iOS tends to. I have not tried speakers, as I have had no need for external speakers on a laptop. (Do note I had these experiences on a 10 year old Thinkpad when I had it with Bluetooth 2.1 and not on my current laptop with either 3.1/4.1, except for the iOS one, and a couple pairs of headphones)

DLoad and re-install the drivers from the HP site...re-boot after.

With bluetooth devices when you delete the device you have to re pair the  device to the laptop.

With the speakers they will have a connect button, which you press while the laptop is scanning for bluetooth devices when the laptop detects the speakers it will show in the bt device list and there will be some questions to answer from windows then you are good to go.

This is a link to some details on how to do this       https://support.microsoft.com/en-us/help/15290/windows-connect-bluetooth-device

Hint: he still needs to re-install the drivers if the device was removed...

I think this says the drivers are loaded and should be working.

. BT icon showing bottom right – click devices and shows noting. Clicked add device and nothing. Ran troubleshoots and checked ‘all BT drivers (device manager) but working properly and have up to date drivers. Restarted.
Device manager: Under ‘Bluetooth Radio’s’ I have -Microsoft BT enumerator and  -Ralink BT 4.0 adapter. Under ‘Network Adapters’ I have -Bluetooth device (personal area network); -Bluetooth device (rfcomm protocol tdi); -microsoft virtual wifi miniport adapter; -Ralink RT3290 802.11bgn wifi adapter; -Realtek PCIe GBE family controller.      THANKS

Have you tried disabling and re-enabling Bluetooth?      Yes Ralink BT 4.0 adapter; MS BT Enumerator; BT device (PAN); BT device (RFCOMM protocol tdi). Restarted my HP

Or have you tried a spare device or headphones to test to see if it works at all?   Although 'discoverable'  HP picks up nothing. Galaxy 5 pickes up speakers and HP

Also, you may have to make the laptop's Bluetooth discoverable. Sometimes its discoverable on the devices but not the laptop itself. Maybe your Bluetooth settings need to be changed on the phone to make it visible for more than a certain amount of time, same goes for the laptop. (Maybe not the speakers, since its speakers. Not quite able to do that on speakers.)    All discoverable.

I also did this ....Made sure both devices are ‘discoverable’. Pair Galax with HP (still on record previous paring) > shows HP as ‘available devices’ > choose HP > got message ‘confirm passkey is xxxxx to pair with HP > ok >unable to pair with HP, make sure HP is ready to pair (it was ready).  Checked on HP the BT devices ....> 0 items > click ‘add device’ > searching for devices , nothing found (also not the speakers previously paired although they are discoverable). 
Galaxy and speakers pair -no problem   THANK you very much, will unistall Ralink BT 4.0 adapter and download again from HP site

Only the Ralink bluetooth 4.0 adapter (listed under 'Bluetooth Radios') ? or also the Network adapters' mentioned in my initial posting. Thanks for assistance, peter

Hallo all. Tried what you smart people suggested, thanks. Uninstalled bluetooth drivers and installed these win7 (64) HP 450 G0, drivers from HP: Broadcom bluetooth (BT) software 6.5; Mediatek (Ralink) 802.11 wireless lan adapter; Mediatek (Ralink) Bt software. Attachment of stuff I have. BT icon showing but no devices and cannot ADD although galaxy is activated and visible. Checked all drivers 'working'. Tried to add HP to Galaxy, searches but cant find it although both are made visible. Yep, I'm lost

BTooth still not adding new devices - downloaded every driver on HP site with Btooth in its name ... Broadcom, Intel (2), Mediatek Ralink (2), Ralink and all drivers are updated . Did not DL 'Qualcomm Atheros. The Intel drivers I downloaded now are not listed in device manager, even with hidden files on.

Btooth icon showing bottom right. Tried to link my HP on Galaxy and got a "confirm passkey to pair with hp", I did but get 'cannot pair with HP. Bottom line HP (allow devices to find this pc is ticked on) cannot link to galaxy or speaker and vice verse.

It may be time to replace it with a new bluetooth dongle then...
