I have a DX Nikon and have been using Nikon SLR and DSLR since 1970 and I have four Nikon DX lenses so I am sticking with Nikon and the SLR style. I want to upgrade my D7100 but I am confused about the options. I like the idea of transfer of images by Blue Tooth. I do not sell my work but I am particular about quality of my images. Budget is not a huge issue; under $2,000. Recommended body?
The D7100 is a good camera. Since you already have four DX lenses, you might want to stick with a DX camera. And there's no reason to leave Nikon (a switch of brands is also a lot more expensive). So here are your options:
Nikon D7200 superseded the D7100 some time ago, so that's the first possible upgrade.
One of the most notable differences with D7200 is a much larger buffer so it can accommodate more shots in a burst before it needs to slow or pause to clear the images from the buffer. That's one of the main complaints about the D7100, that it has a tiny buffer that limits how many shots you can get when shooting rapidly. But if you don't shoot that way, if you take single shots at a more leisurely pace you might never notice the D7100's small buffer. .
Both D7100 and D7200 are 24MP cameras and their "external" features are virtual identical aside from the model name.
However, D7200 got an improved sensor and/or processor that allows it to have a higher ISO range, greater dynamic range and more bit depth.
The D7200 also has slightly improved autofocus... the main difference being that it's able to keep working in slightly lower light conditions. Nikon rates the D7100 to focus as low as -2EV light, while the D7200 can do -3EV.
The D7200
does have built-in WiFi (D7100 requires an added module). But, frankly, this type of WiFi really isn't practical to transfer images. It has very limited range (25 or 30 feet at best) and it's not fast enough. It also makes heavy use of the camera's battery... draining it rather quickly. Probably the main use for the type of WiFi found on D7200 and D7100 is remote operation of the camera... though, again, distance is quite limited.
For practical wireless image transfer would need to get a more pro-grade camera with a separate Wireless File Transfer module. Nikon's are VERY expensive, but there is a third party called Camranger that offers them much more affordably. They sell two models: Camranger 2 and Camranger Mini, which sell for roughly $300 to a bit over $400. These give you up to 300 foot range and are dual band, providing faster data transfer than standard WiFi.
Camrangers work with D7100 and D7200, as well as other Nikon DX models. And, of course, they can be used to remotely operate the camera, too.
If you use a battery grip on your camera, the D7200 and D7100 both use the same MB-D15.
Nikon D7200 is now only available used and sells for roughly $500 to $650, depending upon "mileage" and condition.

https://cameradecision.com/compare/Nikon-D7200-vs-Nikon-D7100Nikon D7500 is the current model in this DX series. It superseded the D7200 several years ago and is a mixed bag.
On the one hand, the D7500 has an articulate rear LCD Touch Screen and it can shoot 8 frames per second (where D7100 and D7200 both have fixed LCD screens and top out at 6 fps).
D7500 also was one of the first Nikon to get Anti-Flicker, which is very helpful solving exposure problems under fluorescent and similar lighting. D7200 has slightly higher usable ISO, too.
Also, D7500 has Blue Tooth (see above regarding it's usefulness). It also can shoot 4K video, if that's important. (The earlier models maxed out with HD video.)
However.... on the other hand, the D7500's is a 21MP camera (not 24MP), it actually has less dynamic range and color depth than D7200 and it's rear LCD screen is slightly slower resolution. It also only has a single memory card slot and there is not vertical battery grip for it. (Vello makes a 3rd party grip, but it's hokey.... uses a funky external wire and doesn't increase battery capacity at all.)
In my opinion, while the D7500 got a few nice, new features, it was in too many other ways a step backward from the D7200. Other people must feel the same, because D7200 have kept their value on the used market better than most digital cameras and were actually selling for more than D7500 when there were still some new D7200 available. Now only used D7200 are available, but some with fairly low shutter "clicks" can be found.

https://cameradecision.com/compare/Nikon-D7500-vs-Nikon-D7200D7500 currently sells for close to $1000 new.
Nikon D500 is their top of the line DX model and is one of the best anyone has ever made. It has higher durability rating and better weather sealing than any of the other Nikon DX cameras. It also has one of Nikon's most advanced AF systems.
The D500 is a fast shooting camera.... ideal for sports, active wildlife, etc. It can shoot 10 frames per second and has all the best features noted above and more.

https://cameradecision.com/compare/Nikon-D500-vs-Nikon-D7200D500 are currently selling for about $1500 new.
This would also be an opportunity to switch to a mirrorless camera, if you wish. Nikon offers two DX format mirrorless that would probably be the easiest transition. There are both positives and negatives to a switch to mirrorless.
Nikon Z 50 is selling for about $860 new (body only), almost $1000 with Z DX 16-50mm kit lens and nearly $1200 with both that 16-50mm and a Z DX 50-250mm lens.
The Z 50 is a 21MP camera using a sensor similar to D7500 and D500. An advantage of most mirrorless, including this one, is an electronic viewfinder (EVF) that can do all sorts of neat things. It can give you an exposure preview, display an electronic level or preview histogram to help with composition and exposure. It also has an AF system that covers more of the image area and can shoot at 11 frames/sec. These cameras also can detect faces to focus upon, and in some cases even peoples' eyes!
One of the downsides is that the EVF draws a lot of power. It has to be powered up continuously any time the camera is in use, and this is a heavy drain on the battery much like using Live View continuously on your DSLR. as a result, you get far fewer shots per battery charge than you do with a comparable DSLR. There also isn't a battery grip available for the Z 50.

https://cameradecision.com/compare/Nikon-Z50-vs-Nikon-D7200Nikon Z fc is a new mirrorless DX model that's coming very soon. It is virtually the same as the Z 50, except the Z fc is a "retro" styled model. It looks a lot like the FM and FE series cameras of the 1980s. Nikon has even produced a cool looking 28mm Special Edition lens to pair with it. And the Z fc comes with your choice of 6 or 8 different colors of leatherette! The Z fc will sell for $960 body only or $1200 with the 28mm SE lens. While I love the looks and general idea of the Z fc, it really is more of a fashion statement than a camera upgrade... it's so similar in specs to the Z 50.
While Nikon has changed the bayonet mount in their mirrorless cameras, a $100 adapter is available that allows you to fully use your DX and FX F-mount Nikkors on the new cameras.
The Z 50 and, to a lesser degree, the Z fc are a bit smaller and lighter than the D7000-series DSLRs. The Z 16-50mm lens is also very compact. However, otherwise there's not a lot of difference lens to lens or other accessories.
Nikon also offers a number of full frame DSLRs and mirrorless. I'm not going to get into those here because any of them would essentially require you replace all your DX lenses. Yes, full frame Nikon can utilize DX lenses... but there will be a significant image crop and in most cases you end up with less resolution than you'd get using the same lens on a DX camera. So it's pretty self-defeating to use DX lenses on FX cameras. You spend a lot extra to get all the "goodness of full frame", then don't take advantage of it! (And, frankly, unless you make big prints from your images, are unlikely to see very much "goodness", even if you spend a lot of money to upgrade to FX lenses, too.)'
In case you haven't guessed by now, I know what I'd do and what I would recommend...
Either stick with the D7100 or upgrade to the D7200. At most this would cost around $650 (for a very low mileage D7200) and, in my opinion, the D7200 was the best Nikon DX camera ever made, for most peoples' purposes. An exception would be sports and other action photography, where the D500 would be a better choice, especially for a pro who makes heavy use of their camera and work under difficult conditions. Sticking with your D7100 or updating to a D7200 will leave a lot of money that you may want to put toward a new lens or a lens upgrade. I don't know what lenses you've got now or what you like to shoot, but as a general rule money put into lenses is more productive than spending the same on a new camera. Lenses almost always can make a bigger difference in your end results. But you may not even need those and best use of the remainder of your budget might be a trip somewhere to take photos or similar.
