Switch Pro Controller won't reconnect through bluetooth

[TeeSeal]

Recently bought myself a Nintendo Switch Pro Controller for use with my switch and PC. When I tried playing on PC the first time I paired it through bluetooth, windows started "setting it up", steam quickly detected it and everything went fine.

However after turning off the controller/PC and attempting to reconnect later, it never does. While the controller attempts to reconnect the steam client freezes, and only unfreezes when the controller gives up (the controller does appear as "connected" during this period in the control panel). Even worse, if I attempt to reconnect the controller while in big picture mode, it causes steam to crash completely.

Connecting through USB works fine. Also I have a PS4 controller that connects and reconnects through bluetooth alright as well.

Never had any kind of wonky controller driver software, just plain steam.

Right now, whenever I want to use the Procon, I have to delete it from the devices in the control panel and re-pair it with my PC, as that's the only time steam seems to interface with it properly.

ONE SOLUTION CONFIRMED (that worked for me...)

I have a gaming laptop (asus tuf), and had the same issue posted here. Paired my 3rd party pro controller, connected perfectly, but after turning it off it didn't reconnect.

So i read that some people were saying that it's a BT 5.0 or 4.0 thing.

My BT adapter is indeed 5.0. So i bought a TpLink BT 4.0 (UB4A) dongle, disabled my built in adapter, plugged the dongle, paired the controller... and well... IT RECONNECTS NOW!!!

BT 4.0 has TERRIBLE range compared to 5.0 and at a farily short distance it'll have lag, but well you win some, you lose some.

Hopefully some of you guys might fix the issue trying this, to everyone else, don't give up.

I tried using a Ugreen 5.3 Bluetooth adapter(cm656); it could perfectly reconnect to the computer but could only connect to one Switch Pro controller. If I tried to connect two controllers, it would fail. Then, I bought a 5.0 Bluetooth adapter(cm390), which could connect two controllers for normal use, but it couldn't reconnect to my computer. It wasn't until I bought a 5.4 Bluetooth adapter (cm748)that it worked perfectly.

My Switch Pro controller is brand new. It connects when I pair it with my 5.3 dongle, but, like the OP, when I turn the PC off and try to reconnect it when I turn the PC on again, it won't do it. I have to remove it in Windows settings and re-pair it to get it going again.

It seems logical that a new controller would conform to 5.4, so, I've ordered a Ugreen 5.4 dongle and I'll see how I go. If that doesn't do the trick I'll find a 4.0. I really like this controller and I'll get it going full time if it's the last thing I do! (It had better not be, I want to live, LOL!)

[rogb1970]

Done a bit of digging...

According to official Nintendo specs, the Switch Pro controller uses Bluetooth 3.0. A 4.0 dongle is more likely to be backwards compatible with 3.0, which is why 4.0 dongles seem to have worked.

According to blurb on Newegg, a 5.4 dongle is backwards compatible with 3.0, so, that will be why that works. I just hope the Ugreen 5.4 (CM748) I bought earlier will work too.......

[ApxuBbI]

To me it's still unclear if this is also due to backwards compatibility, why some versions dropped support, and later restored it.
Feels like certain functions got broken, and only in new revisions these were fixed.

[rogb1970]

Hard to say. It's a really nice controller. You'd think that, over the years, Nintendo would have updated the firmware. I know Sony made several iterations of the DS4 over the time that was new.

My current dongle says on it that it's 5.1, however, Windows thinks it's a 5.3 and loads a Realtek driver for it. I updated it with a 5.1 driver, but, it behaves in exactly the same way as the previous driver did in that the Switch Pro won't reconnect when you turn it on.

I uninstalled the adapter in Device Manager and redid the driver, still no different! I went to try my Dualsense, only idiot me forgot that I'd have to re-pair it. That disconnects and reconnects just fine, so, it isn't a defective dongle, it just won't play nice with my Pro controller.

Hopefully, sometime this week, I'll have the 5.4 dongle, which is the same make and model as the guy in post #62 has and everything will play nice with that and be hunky dory. If it is I can just tell everyone to get that particular dongle.......

Hopefully 5.4 will be the true fix like everyone is saying and this will just become a memory

[rogb1970]

Hopefully! What seems to be happening is that when you pair the controller with the dongle, the dongle gets what it needs from the controller and it pairs. When you turn the controller on after turning it off, for some reason, it isn't getting what it needs from the dongle and it turns off again.

I don't speak tech, but, something in the Bluetooth 5.4 specs mentioned bidirectional, it's possible that this is giving the controller what it needs to connect again. Then again, what do I know, like I said I don't speak tech, LOL!

I've downloaded BetterJoy so if all else fails I'll give that a go....

[rogb1970]

One thing to check. Look in Device Manager when the dongle is plugged in. Right click the driver and look at the Advanced tab. There you will see details of the firmware, look at the LMP number, that will tell you which version of bluetooth it is. LMP 12.4 is 5.3, LMP 13.2 is 5.4.

[rogb1970]

If you get a Ugreen CM748 and the generic driver that Windows loads doesn't show the LMP as 13.5 you can get a driver from Ugreen here:

https://www.ugreen.com/pages/download

Type CM748 in the search box, hit search and click the image to bring up the download window and click Driver. The driver will then download.

Create a folder to put the driver files in. When you open the zip, the first thing you may see is a load of garbage in the folder name, don't worry, it's Chinese and Windows can't read it! Open the folder and extract everything you can read to the folder you created. The setup.exe will install the driver. You will see Barrot in Device Manager, that's the chipset it uses.

[rogb1970]

I have good news! Bluetooth 5.4 works! I plugged the CM748 in, installed the driver and the correct LMP code shows in Device Manager. I paired the Switch Pro controller with it, entered Steam, the lights came on and the controller worked. I then turned it off again, pressed B, the seek light came on for a bit and then it lit back up again!! IT WORKS!!

Even after a restart, I turn it on, launch Steam and it lights up. It will only light up when it detects that Steam is open though.

Whatever, I can confirm that Bluetooth 5.4 works. The Ugreen CM748 is probably the best dongle to go for as you can download and install a driver for it, any other may just have to rely on what Windows loads and I don't know if Windows 11 has drivers for Bluetooth 5.4.

Oddly though, even though you can find the driver for the CM748 on the Ugreen site, they don't list that model in their store. I got mine on eBay, so, look one up and see what you find.

GOOD LUCK!

Thanks for the update @rogb1970, after reading your update I also tried the UGREEN 5.4 since there was a few glitches with the UGREEN 5.3 and the Gulikit KingKong 2 (lag, signal drops), and the 8BitDo SN30 Pro+ (random disconnections);

And so far, the UGREEN 5.4 works without either these issues, and also reconnects with the Nintendo Pro Controller.

Pretty much the best choice of Bluetooth adapter (i'm using the long range one here https://www.aliexpress.com/item/1005006320967899.html)

[rogb1970]

No worries!

I also got a new keyboard last week and the Ugreen works well with that too,

Hello Rogb, I'm glad to have found your post.

Whenever I go to ugreen to download the drivers, they no longer exist. See image: https://i.imgur.com/N6ZrqSF.png

Can you upload the drivers perhaps to your google drive?

Additionally, I looked up CM748 on both amazon and ebay and found nothing.

The aliexpress link no longer works. Any chance you guys can help me find the exact cm748 model?

I found 2 different ugreen 5.4, can you send a picture of what the adapter actually looks like and upload it to imgur.com ?

Here are the only 3 I found currently:
https://www.ebay.com/itm/176255558184?itmmeta=01HXKXFS80A50ZEZG5VMP5RMHP&hash=item2909a66228:g:2xUAAOSw63dl2g-f
https://www.ebay.com/itm/326018653054?itmmeta=01HXKXFS80N5W36053HQ58HQV8&hash=item4be839db7e:g:34cAAOSw63dl1FQU

There are only 2 left in the first link and 1 left in the second link so I would have to buy it asap. The 3rd link has 25 left.

I did find a few on aliexpress:
Similar to the ones above: https://www.aliexpress.us/item/3256806134653147.html?spm=a2g0o.productlist.main.1.2a9d3e4ezOK8Jb
and the long range one
https://www.aliexpress.us/item/3256806511209789.html?spm=a2g0o.productlist.main.3.2a9d3e4ezOK8Jb&algo_pvid=b8963eeb-2923-4c3d-af35-3006b8fa2b6a

Did you buy the longrange one and verified it is working? How about the short usb one?

I know lots of questions but I truly want to get this resolved and then do a community post about this issue and how to fix on several Nintendo forums.

I have not tried my Switch Pro controller yet. I am using the Official NSO N64 controller with bluetooth: https://www.nintendo.com/us/store/products/nintendo-64-controller/ and have the same issues as you guys. 1st pair is a success and putting it to sleep and turning it back on does not work without unpairing, removing drivers via device manager and then trying 4-5 times until it works. I just want to play my Nintendo 64 games with upscaled resolution rather than letterbox on my TV Q.Q

[rogb1970]

The first and 3rd eBay links are the correct one as is the first Ali Express link.

This link for the driver worked:

https://uk.ugreen.com/pages/download

As before, type CM748 in the search box and click the image.

Good luck!
