Unlike its newer replacement (the D3500), the Nikon D3400 has some wireless capabilities. That said, it’s not a full-featured wireless capability. It doesn’t have wifi, so you can’t use it to control the camera remotely, for example. But it does have Bluetooth, which you can use to download images from your camera to your phone wirelessly.
Chances are that if you’re on this page you’re trying to turn on Bluetooth on your Nikon D3400 but the Bluetooth option is grayed out.
The reason is that you can only activate and connect the D3400’s Bluetooth through the SnapBridge mobile app. Put another way, to use Bluetooth on the D3400, you have to establish the connection through the SnapBridge app, not through the Bluetooth menu item on the camera.
How to Connect the Nikon D3400 to SnapBridge
On the camera’s menu, make sure that the Network Connection option is set to On and Airplane Mode is Off.
Setup > Network connection
Setup > Airplane Mode
You’ll need to download the SnapBridge app to your phone or tablet. Open the app.
On your camera, go to
Setup (the wrench/spanner icon) > Connect to smart device.
While there’s still plenty of room to improve user-friendliness, between the camera and phone the onscreen prompts offer a reasonably good explanation of what you need to do in each step, but the gist is that you first need to pair the D3400 to the phone (through the SnapBridge app) and confirm that the pairing code matches. Then it should take you to the main screen where you can download and view images from the camera or enable the auto-download functionality.
List of Paired Devices
You can find the list of paired Bluetooth devices under
Menu > Setup (the wrench icon).
You can see whether Bluetooth is enabled on the everything-and-the-kitchen-sink information display on the back screen. To access it, press the Info button on the back of the camera. The Bluetooth icon is at the top left.
Things Worth Knowing
If you’re trying to connect your camera to the SnapBridge app, establish the connection directly through the SnapBridge app. That is, don’t establish the connection first through Bluetooth settings.
You can’t connect the camera to any random Bluetooth device, including, unfortunately, Bluetooth remotes or intervalometers.
You can put the D3400 into airplane mode, turning off wireless and Bluetooth connections. You can find that setting under
Menu > Setup (the wrench icon).
If your camera light stays on when you’ve turned it off, it’s likely that you have Bluetooth enabled and set to transmit data to a wireless device. The Bluetooth stays active even with the main camera power off. You can turn off that functionality by disabling the “Send while off” feature under
Setup > Bluetooth > Send while off. And you can turn off Bluetooth entirely by turning off the network connection (
Setup > Bluetooth > Network connection).
SnapBridge can be—how shall we put this—a little frustrating to use. It is not my favorite app, and it often takes far too long and too many tries to establish a connection. I haven’t found a magic solution that solves the connection issues in all cases, but some things to try are:
- Try again. It sounds obvious, but it often takes me 3 or 4 attempts to establish a connection successfully.
- Delete the SnapBridge app and reinstall it.
- Remove the camera’s connection from the phone’s Bluetooth memory.
- Reset the camera (be warned that you’ll lose most settings doing this).

Nikon D3400 Accessories
Here are some of the key accessories and official part numbers for the Nikon D3400.
Battery & Charger for Nikon D3400
If you're looking for a replacement or spare battery for your D3400, the Nikon D3400's battery is model EN-EL14a. It's a rechargeable lithium-ion battery that's also used by many other Nikon DSLRs (7.2V, 1230mAh). You can also find very good aftermarket versions, like this one from Watson or these from PowerExtra that provide more cost-effective alternatives.
- ✔ Battery Specs：Capacity: 1500mAh / Battery Type: Lithium-ion / Voltage: 7.4V / Come with CE...
- ✔ Standard Compatible with Nikon EN-EL14 EN-EL14a：Ideal Replacement Battery for Nikon Coolpix P7000,...
The battery charger is model MH-24. It's an AC quick charger that plugs directly into the wall socket. Unlike many other cameras, you can't charge the Nikon D3400's battery in the camera. Some of the aftermarket batteries come with a dock charger, which can be a cheaper way to solve the problem.
A memory card is right up there with a battery as an essential accessory for your D3400. But, unlike the battery, it doesn't come with the D3400.
There's no official SD card for the D3400, but there are some that make more sense than others. Some older-model cards are too slow. And some newer, faster (and more expensive) SD cards will work in the D3400 but go beyond what the D3400 can make use of, so you'd be paying for SD card performance that the camera can't take advantage of.
I've put together more detailed SD card recommendations for the Nikon D3400. But here's the Cliff notes version. Any of these make for a good choice and are reasonably priced:
USB Cable for Nikon D3400
If you're looking to connect a Nikon D3400 to a computer to download your photos and videos, you'll need a USB cable. If you've misplaced the one that came with the camera, replacements are easy to find and not expensive. If you'd prefer to get the Nikon original, the model number you're after is [UC-E20](https://www.nikonimgsupport.com/eu/BV_article?articleNo=000005024&configured=1&lang=en_GB), and you can find them at camera specialists like B&H Photo.
But there's no particular reason you have to stick with the Nikon-branded one. There are also many aftermarket micro-USB cables that will work just fine. But there is a bit of a catch: not all micro-USB cables will work with the data transfer that the D3400 needs.
By all means try any others you have lying around to see if the camera mounts to your computer--it won't hurt it. If it doesn't mount, you can pick up replacement data transfer cables like this aftermarket version or this one.
And a reminder that this is only for data transfer. You can't charge the battery while it's in the D3400. For charging, you'll need the MH-24 charger or equivalent (see above).
- Length: 3FT, light and easy to carry.
- Brand new, high quality usb 2.0 Data cable/lead.( Non-OEM )
Camera Strap for the Nikon D3400
There's no particular reason you have to use the original Nikon strap with the D3400--any camera strap will work. But if you want to replace the original (the black one with the gold/yellow Nikon branding), its model number is AN-DC3.
There's also a huge variety of other good alternatives. My personal favorites are the ones by Peak Design, which come in especially handy if you're going back and forth between multiple cameras because they come with a quick-release system. And they're very strong.
Remote Shutter Release for Nikon D3400
There's a number of different options for remotely triggering your D3400 (unlike the D3500, where this functionality was removed).
The first step is Nikon's ML-L3 wireless remote. It's very simple--just a single button, without any intervalometer or other features--and with an infrared signal, its range is limited to about 16 feet or less. But it's inexpensive and designed by Nikon for use with their cameras.
And there's a variety of other wireless receiver/transmitter kits that can be set up to work, some of which get up there in terms of complexity and price.
Lenses for Nikon D3400
One of the great things about DSLRs--and especially ones that use a long-standing mounting system like Nikon's F-mount--is that there's a huge variety of lenses that you can use. So there's no "right" lens to use.
But for the D3400, in general, you want to look for lenses that have Nikon's F-mount system and that are designed for DX camera bodies (that's the cropped sensor size of the D3400). And you'll probably want one that has autofocus. None of these things are requirements, though--there are any number of ways to use adapters or manual older manual-focus lenses--but sticking to those basics will make things easier if you're looking to expand your lens collection.
If you're after some recommendations on lenses to get for the D3400 to step beyond the kit lens that comes with the camera (usually a basic 18-55mm zoom lens), here are some ideas that are sensibly priced and greatly expand your options:
Nikon AF-S DX 18-300mm ƒ/3.5-6.3G ED VR zoom lens. If you had to choose just one lens to take with your traveling, this is a great choice. It has a very wide zoom range. At 18mm (equivalent to 27mm on a full-frame body), it's great for interiors or landscapes. At 300mm (equivalent to 450mm on a full-frame body), there's plenty of reach for wildlife, sports, or dramatic sunsets. It has vibration reduction, is surprisingly compact and light, and is competitively priced. Sigma also makes a good version that's a bit cheaper but great quality.
- Maximum magnification of 032x
- Angle of view from 76 degree to 5 degree 20'. Focal length range: 18 300 millimeter, minimum focus...
Nikon AF-S 50mm ƒ/1.8G lens. It's hard to go past a 50mm prime lens for versatility, fun, and learning photography. They're fast, which means they're good in low-light as well as give you that nice blurry background while keeping the subject sharp. They're inexpensive. They're often very sharp. And they're small and highly portable. This is the ƒ/1.8 version. Nikon also makes a B&H Photofaster ƒ/1.4 version, but it's about double the price. because the D3400 has a cropped DX sensor, the 50mm lens will become a slight telephoto perspective, equivalent to a 75mm lens on a full-frame camera (i.e., 35mm equivalent). Which makes it all the more useful as a portrait lens, whether you're taking formal portraits or candids of the family. And if you want a more traditional "true" 50mm perspective, you can put the 35mm ƒ/1.8G on the D3400 instead.
- Fast, upgraded f/1.8, compact FX format prime lens. The picture angle with 35 millimeter (135) format is...
- Focal length 50 millimeter, minimum focus distance 1.48 feet (0.45 meter)
Nikon D3400 Body Cap
If you're transporting or storing your D3400 camera body without a lens attached, you'll want to put on a body cap over the opening where the lens goes. That prevents dust and moisture from getting inside and causing havoc (and pesky dust bunnies on your photos).
The camera comes with one, but they're easy to misplace. The model number for the replacement part is BF-1B. It's the same cap used for all Nikon F-mount camera bodies. And this is a great opportunity to save a few dollars with an aftermarket version. They're often sold paired with a rear lens cap, since you often need both of those things when removing a lens.
Nikon D3400 Rubber Eyecup
If the rubber eyecup has been knocked off when you take out of your camera bag, the replacement part model number is DK-25. There are also slightly cheaper aftermarket versions, such as the ones by Vello or JJC.
- Made from soft and durable silicone + high quality ABS
- Provide cushioning around the camera's eyepiece, and are especially useful to eyeglass wearers
Battery Dummy for Nikon D3400
A battery dummy is used for longer-term power supply to the camera. They're especially useful for things like time lapse photography, astrophotography, or using your D3400 as a webcam.
It's an accessory that fits into your camera's battery compartment. By itself, it doesn't provide any power, but it's attached to a cable that you can then attach to different power sources such as AC power or a larger battery pack.
