Windows 10: Bluetooth not working - error code 45

Hi there,

I have this issue with bluetooth. It has always been working fine, more or less: it was only hard to turn on every time i needed it, but it worked.

Until last week I guess, it stopped showing. At all.

Today I went searching all over internet for some help, but nothing worked. I tried installing drivers from the Acer site I have an acer travelmate. The driver can't install because something is not updated.

So I tried to check on windows update but everything is updated...

Then I went to device management and I saw that there wasn't any bluetooth voice. I had to click on Show hidden devices to see all the bluetooth entries...

I realised I had the Generic bluetooth adapter, and if I right click on it there's no update voice, it will only let me uninstall it.

Since i'm not an expert, i didn't uninstall it. I went to proprieties and I saw this 45 error code: the hardware device is not connected.

Since the bluetooth hardware is all inside, i don't thing it is possible for it to disconnect in any kind of way. I haven't even dropped my PC lately because it is always in the same exact place, on my desk...

I'm getting a bit desperate. I just bought airpods and its annoying me a loooot because i can't use them hahaha.

Anyway I'll be truly grateful to anyone who will help me.


[side note: sorry if my english is not perfect. I hope everyone understood the general concept]

bluetooth code 45

My bluetooth suddenly stopped working and had a Code 45. It's Lenovo ideapad 110 with Qualcom Atheos Bluetooth 4.1. I searched every help forum and tried all the suggestions,. None worked, so in desperation I uninstalled it. Now when I tried to reinstall
the driver it says I have no bluetooth installed. Any suggestions on how to reinstall it? It's inside the laptop. Thank you.

 

Windows 10 Bluetooth error code 45?

Hi Monil,

You will see this error when a previously connected device is no longer connected to the computer. This error code is only used to indicate the disconnected status of the device and does not require you to resolve it. You can just simply reconnect the device
to resolve the problem.

If you continue getting this error even after reconnecting the device, we suggest running the Bluetooth troubleshooter. Here's how:

• Click the Start menu button, type 'troubleshoot', and press
  Enter.
• Select Bluetooth, and Run the troubleshooter.

Alternatively, you can also follow Sheshanarayana Ravishankar's guide on this
thread to resolve the issue.

Let us know if you need further assistance.
