Bluetooth not working on a PCIe slot

You did not mention it but did you download the Intel Bluetooth drivers here? Also you can purchase extension cable for the antenna here which would allow M.2 installation again.

I have a Dell Optiplex 7070 SFF running Fedora. I have an Intel network card ax210 installed in the m.2 slot and it works, the only problem was that cables for antenas were too short and the only solution that I thought was to buy a PCIe adaptor and use the card in the PCIe slot.

Now the Bluetooth is not working, when I open the Bluetooth settings it says 'Plug in a dongle to use Bluetooth'. Wifi works.

I don't know where the problem is, is it software? is hardware? I have the Intel drivers installed

The AX210 card is a combo wifi 6 card with wifi and bluetooth.  With a standard single lane 1x add in card with no bifurcation, wifi will go over PCiE, but you need a separate connection / more bandwidth for bluetooth 5.1.   So you'd need to buy a (standard) pcie add in card that supports separately routing the bluetooth data via the USB header on the motherboard.  Or if you have one, you need to plug in the USB cable to the motherboard header. That is why all the AC and AX wifi /BT pcie add in cards that you see have separate PCiE + USB connections.  The USB cable is for transferring the bluetooth data, the pcie lane is for transferring wifi data.

you must use x4 or greater due to the 10w power limit for X1

Check out amazon, and do a search for "wifi 6 add in card," every single option on the first page of search results is a  PCiE X1 add in card, there are no x4 options listed there.  

Another thing to consider is PCiE 3.0 x1 transfer (985 MB/s) vs. wifi 6 max transfer (1200 MB/S), equals theoretical bandwidth cap/bottleneck.

those cards you refer are NOT wifi6 and they too require flexbay header for the Bluetooth.

REAL AX200 and AX210 cards use USB for bluetooth and REQUIRE at LEAST X4 PCI-E A E keyed M2 2230 slot. The bluetooth isnt working because the USB connection for BT on the card is not connected and will not be connected via PCI-E slot or M2  M keyed Slot.

Board Form Factor M.2 2230 A E keyed
System Interface Type Wi-Fi(PCIe), BT(USB)

https://www.intel.com/content/www/us/en/products/sku/201974/intel-wifi-6-gig-desktop-kit/specifications.html

So again has nothing whatsoever to do with bandwidth and everything to do with what pins are available on A E keyed 2230 M2 slot.

I used the parts I linked with an official INTEL wifi 6 card in an X16 slot wired as X4 with the aformentioned PCI-E to NVME 2280 adapter and the NVME  M keyed adapter to USB and A E keyed adapter and it works correctly with linux as well as with windows.  No drivers to install it just works.

X1 Slot 10W

X4 Slot  25W

X16 Slot 50W to 75W depending on Max power combined for 3.3v/5v Rails as well as 12v 25 Amps Split into 2 rails with 18 amps being max for any given 12v rail.  Has nothing to do with power supply watts has to do with fire Safety standards for UL 94v.

@r72019  I do read and I also know exactly what I am talking about.  I have clients who ordered the FAKE AX200 cards and they do not work because they are not actual AX200 INTEL cards.  Actual INTEL cards have Native Windows 10 drivers.  Nothing to download they just work.

"They are actually all advertised as wifi 6 pcie add in cards, and the pcie add in adapters all contain ax200 or 210 cards in the adapters if you look at the photo. "

While they say AX200 or AX210 thats marketing not specifications. They are fraudulently marked AX200.

Its like Fake GPU's they put that on there to fool users who don't know any better.

Referring users to those cards will not solve their problem.

REAL AX200 and AX210 INTEL based cards do not need driver downloads for Windows 10 21H1 or Ubuntu 20.04.2

I ordered an actual INTEL AX200 Kit.

https://www.amazon.com/dp/B07ZVYKRW9

I then found out that it needs 2 Adapters to go into the Black X4 slot on a dell.

The first Adapter converts M2 2280 M keyed PCI-E to M2 2230 A E keyed M2 and comes with a USB cable for the Bluetooth Section as this is not available from ANY PCI-E slot.  Never has been.

I then found that I did not have a flex bay USB connection so I ordered USB B to 10 pin Flex bay cable to run from outside to inside.

I then added the adapter to an adapter and adapted it to PCI-E X4 to M2 2280 adapter.

You put the WIFI 6 card in this

https://www.amazon.com/gp/product/B07WBXP632

Then put AX210 M.2 A/E  WiFi Card in M.2 NVME  M keyed Not the SATA keyed B & M

Then put the adapter with wifi6 card mounted on it into the PCI-E keyed slot on this card.

https://www.amazon.com/gp/product/B07JKH5VTL

The Bluetooth USB must go to a flexbay or similar port on the motherboard or be fed to the outside and plugged in that way.

Yes, we've already established you need the USB header, that was actually the entire point of my very first post that you started responding too.  

They are actually all advertised as wifi 6 pcie add in cards, and the pcie add in adapters all contain ax200 or 210 cards in the adapters if you look at the photo. 

And that is also my point, so again there are bandwidth issues running wifi 6 over PCiE x1 add-in cards because the transfer speed of wifi 6 exceeds PCiE x1, you aren't going to reach the full potential and irrespective of the BT aspect.

The poster was all set. I'm not referring anyone to a specific product.

My point/gripe was that virtually all the combo wifi card + pcie adapters currently on the market  unfortunately utilize pcie x1 based add in cards. 

If you want to utilize x4 to gain the full potential, you need to purchase the card + adapter separately.  Because that type of product isn't readily available in the current market, and that will cost a substantial premium versus being able to fairly easily get a combo package for around $22 on the not infrequent prime sales.  I've purchased five AX200 and AX210 combos on amazon over the last three months, and I can verify they are not fake cards. 

They all work properly, are recognized in device manager, and Windows auto installs the drivers upon first boot, no disk is required. 

Most do include a disk, although there is no reason to use it nor have I ever used it.  I did look and the included disk only contains a copy of the intel driver (https://downloadcenter.intel.com/download/30542/Windows-10-Wi-Fi-Drivers-for-Intel-Wireless-Adapters).  Presumably the disk is there for people who do not already have access to internet when they first install the wifi add in card. 

In any event, I haven't experienced any issues with the combo pcie x1 + ax210/200 packages, nor has anyone for whom I've recently built a PC with one of these cards, either with the bluetooth function or the wifi function. 

I am familiar with the 1050ti scams, much more money to be made there than a $20 card, but those are easy to spot upon driver attempted installation or even by removing the shroud/heatsink you can physically see it's not a 1050ti under there.  

These wifi 6 combo adapters, if you remove the heatsink there's an Intel sticker on the card under there (yes, I've checked that too). Anyway, I'm not promoting any specific product, couldn't care what people do or do not buy and I am not affiliated with any seller on amazon.  There are many different PCiE x1 wifi 6/BT 5.1 options out there.  I was just pointing out that these type of readily available products have been functioning fine for me.   Better even than the Killer AC card included with my Dell system. 

This problem puzzled me, too. I've a wifi 6/bluetooth 5.1 pcie combo card. Wifi is working, of course, but I couln't find a F_USB port or a matching card reader port on the mainboard (Precision 3640). I was on HP workstations for many years and could just plug in the card (usb header on board) So I had to order one of those flexbay headers from China. It doesn't look tidy in the way it works, and one usb port is engaged by the flexbay.

A & E keyed wifi will be seen in m2 slot but Bluetooth for AX200 or AX210 requires USB header.

It will have to be put thru a slot adapter that is modded from outside to inside.
