Bluetooth tracker for searching. Personal detective for your child. Reviews of GPS and Bluetooth trackers: pros and cons of modern device models. How does a Bluetooth tracker work?

There is a video: the Phone Halo company presented the world's smallest Button TrackR, which is a beacon in the form of a coin or a button. It can fit comfortably in a pocket, purse, used as a key ring, or anywhere else a regular coin can fit. The beacon has additional functions and works with all smartphones.

ButtonTrackR is a miniature tracking device for people, pets, things or vehicles - e.g. It comes with a convenient free application, which can be installed on a tablet or smartphone. The range of the device is approximately 30 meters.

One can track up to ten Button TrackR beacons simultaneously. Moreover, the application is designed to work with operating systems both iOS and Android. As the tracker moves away from your device, the latter will show a distance indicator and give appropriate signals.

One more interesting feature The beacon is able to work in both directions. That is, if the tracker is near you, but you cannot find your smartphone, just press the beacon button for the smartphone to signal and attract your attention.

Since the Button TrackR beacon works with smartphones, the application is able to remember its location and show it on Google maps just like trackers do. The beacon button can be attached to the bicycle frame or other surface either with regular adhesive tape or using a special connector for laces and rings.

In the application to each of the smartphones assigned to them or tablet computer 10 beacons the user can pin the corresponding image. In this case, the application will give a signal if it is removed from any of them. You can also set different signals.

In addition, the application has a “ ” mode that will constantly signal if your smartphone is stolen. To do this, you just need to simply press the only button in the beacon.

No less interesting is the option for the beacon to respond if you and your smartphone are too far away from it. In this case, the collective tracking mode is activated and the smartphone of any user with the same application installed will send you signals indicating the GPS location of his location. Wherein paid subscription GPS services are not required.

Technical characteristics of the beacon - Button TrackR buttons include work with the energy-efficient version of Bluetooth Low Energy 4.0 (LE), availability with the ability battery life within one year without the need for replacement, and also measures 4 mm in thickness and 25 mm in diameter.

The company submitted an application to the innovative web project Indiegogo, where it intended to collect 15 thousand evergreen currency units. The developers were probably very disappointed when they saw this moment an amount equal to 2000% of the required amount. This is true - users were so interested in the miniature novelty that they shelled out almost a third of a million dollars from their bourgeois pockets.

For now, each user can leave their order to receive the world's smallest beacon - the Phone Halo Button TrackR tracker in August 2013. Moreover, to receive one unit you need to sponsor the project for 25 USD, for two – for 40, for five – for 90, and for 100 units – for 900 USD.

I hope my article was helpful. If you liked the article, then share it with your friends!

I decided to take a look a little GPS navigation, I bought an inexpensive module. At the same time, in order not to get lost in three pines, based on it I decided to build myself a compact tracker that can easily connect to cell phone or laptop.

The device is based on a GPS module from Quectel – L10. Compact (22x17mm), inexpensive (~300 rubles), easily soldered chip (pitch 1.1mm). On board which contains UART, USB, I2C, SPI, in general, a wide variety of interfaces for interfacing with a computer, a microcontroller, or anything. Supports both passive and active antennas of different types. The standard protocol for such devices is NMAE.

I was primarily interested in UART, because... it is the most convenient for pairing with MK and other peripherals. Thus, I hooked up the output of the global positioning system module to one UART, despite the existing built-in USB. The result is the following beast:

The diagram shows that the module is connected to a USB-UART converter and a BT module via UART. USB powered and Bluetooth is supplied through Schottky diodes (VD1 and VD4) to the GPS module, which allows it to start with each of them without powering unused parts of the tracker; the LED1 or LED3 also indicates the communication source used. The blue tooth and GPS module have their own status LEDs LED4 and LED2, the second blinking every second indicates that satellites have been detected and the module is receiving location data. For hot start, the GPS has a 3.3V battery to store data in volatile memory; without this battery, the module takes from half a minute to a minute to search for satellites.

To place all this in a compact case for 3 AA batteries the board had to be made double-sided.

Its dimensions are 50x30mm. GPS module – L10. Bluetooth HC-05 with linvor V1.5 firmware. GPS active antenna ANT GPS GA-240 UFL-F10CM glued to the . The USB-UART converter is made on a CP2102 chip in a QFN-28 package. Stabilizer VR1 at 3.3V L78L33ABUTR in the SOT-89 package, its piping capacitors C1, C2 0805 0.1 µF and chip-tantalum capacitor C3 of size A or B at 10 µF. Shottky diodes were used - MBR0540T1 VD1-VD4, of which excess battery voltage is extinguished at VD2 ( possible replacement SS16), VD1 and VD4 decouple the power circuits from the battery and USB. The VD3 diode can be replaced with any diode. LED1-LED4 are any chip LEDs with a current consumption of no more than 10mA; they have resistors R1-R2 of standard size 0805 and R5-R6 of standard size 1206 with a resistance of 360-510 Ohms as current limiters. R4 0805 100 Ohm. R3 is a jumper that also acts as a fuse; in addition to R3, there are 5 more jumpers on the board, all of them are made in the form of 0 Ohm resistors in the 1206 case, two of which S1 and S2 should be installed when using an active antenna, but with low current consumption. Capacitors C5 and C6 are size A chip tantalum at 4.7 and 10 microfarads, respectively. C4 0.1 uF 0805. The Bat2 CR120 3.3V battery is secured with two homemade brackets obtained from some output part. An SMD mini-USB socket is used. U.FL antenna socket. The housing uses a closed holder for three AA batteries - ZH292. When operating from a battery (Bat1), the design is powered by a 3.7V Li-ion can 14500.

When installing the Bluetooth module on the board, you need to isolate the contact pad located on the back side from short circuits with the Rx, Tx and power lines; this can be done by applying a small amount of capon varnish to the lines on the board under the module and the pad on the module itself.

Practice has shown that one blue tooth is enough for comfortable work, so I propose a simplified version of the device diagram.

The board has become single-sided, but has become 2 mm longer; nevertheless, it can be stuffed into the same case. The main parts are the same as on the previous board. The binding has changed a little. R1 and R2 360-510 Ohm 0805. VD1 Schottky diode SS16 or MBR0540T1. VD2 Schottky MBR0540T1 or any other diode. C1 chip tantalum 10 µF size A or B. C2 ceramic 0.1 µF 0805. R3 0805 100 Ohm. The battery is located on the opposite side of the board. I was able to get by with one jumper. Just like in the first version of the board, you need to isolate the contact pad under the Bluetooth module.

The tracker does not require a microcontroller and should start working immediately after assembly if the components are configured as default: speed 9600, 8N1.

After turning on, the tracker immediately becomes visible among the available Bluetooth devices to connect. After pairing and connecting with it, you can start working from any navigation program that supports GPS.

After power on GPS receiver it immediately starts working, first it searches for satellites. When using a battery, the search takes a few seconds, then it begins to process them. In good weather in open space, location data becomes available within 5 seconds after switching on. In cloudy weather, it may take several minutes to enter the building near the window.

A few words about the means used. On my phone I use the programs MapNav, Yandex maps and Mail traffic jams. Among computer programs, 2GIS and Google Earth cope well with their tasks.

It would seem: for recent years five tracker is understood very clearly - it is a bracelet for the wrist; All of them are synchronized with a smartphone via Bluetooth in 99% of cases. So why, when they say Bluetooth tracker, do they mean something completely different?

What it is

Most often, the term “Bluetooth tracker” refers to a search tag. There are a huge number of them, different manufacturers. The popularity of this category began with Tile products.

The functionality and capabilities have not changed for a long time: the Bluetooth tracker connects to a smartphone, with a proprietary application, and sends a signal about the connection being broken when the smartphone and the tag move away to an unacceptable distance.

Bluetooth animal tracker

No, there is no such thing. Theoretically, you can try to attach any tag to a cat or dog, but this will be of no use: the distance is too small. Sometimes they say that you can put it in a child’s pocket, for example, in a large shopping center, and then if he accidentally moves ten meters away, you will hear or feel the signal from your smartphone.

Bluetooth GPS tracker

This is also a myth, largely created by translation errors from Chinese sites. What it is based on: tracker markers in the application show the location on the map: the location of the last break. And only that. That is, if the thing has moved since that moment, then it is impossible to track it. However, the GPS prefix is ​​still retained by unscrupulous sellers.

Who needs a Bluetooth keychain?

The thing is quite useful: put it in your wallet, throw it in a folder with documents, or tie it to your umbrella or keys. You forgot an important envelope at home, went downstairs and heard a signal, but going up one floor is still easier than returning home from work. Or you forgot your umbrella in a cafe: returning in seconds and returning in the evening always has a different effect.

How does a Bluetooth tracker work?

The key fob tracker works in conjunction with an application: most often, inside the software you will find a map where the locations of breaks are saved, as well as signal settings, etc. Anything incidental, such as charge status. As soon as you move an unacceptable distance from the tag along with the smartphone to which the tracker is attached, both the tag and the smartphone will give an alert. You will remember what needs to be taken, and you will take it.

Examples?

The most popular in the world is Tile. Despite the narrow functionality and relatively high price, this bluetooth keychain is loved. The brands TrikR and StickNFind are also known in Russia.

We have been successfully selling for several years now. Recently, a much cheaper alternative has appeared. The tag is made a little simpler, the Bluetooth signal is lost more often, but the application is Russified.


Unlike Tile trackers, which were clearly created with an eye on owners of Apple smartphones and tablets, Nut is closer in spirit Android users. Such associations immediately arose in me thanks to the design of the trackers, and were later reinforced by the nuances of use. Accordingly, comparing them is somewhat reminiscent of the battle “iOS vs Android”. I liked the Nut trackers more (well, yes, I have Android) due to the presence of an active Anti-loss mode, and also because they are more accessible, more practical, and the user can manage them at his own discretion, without turning to the “big brother”. The disadvantages of Nut are its flimsy body, not protected from dust, water and dirt, and an inconvenient (and not particularly reliable) mount. The presence of Silent Mode and the dependence of the notification volume on the phone’s system settings cannot be clearly classified as pros or cons, since they can be convenient, but require more attention and control from the user. As for me, ideal option There would be a tracker with an Anti-loss mode and the ability to replace the battery in a Tile case, but, alas, you have to choose. Or use both types of trackers - each for those tasks that it can handle better. Of course, devices from both brands are only compatible with their own application.

Probably each of us has lost something. Either your phone or TV remote control got lost in the apartment, or you left your bag in the store, or when you left the house you didn’t take your wallet or car keys. You have to search or return, wasting precious time. Okay, the phone - you can call it from another phone or find it using a special Internet service. How to ring the keys?

This is exactly what Bluetooth trackers were invented for. We have already looked at their work in more detail using the example of Tile, now let’s see how similar devices of the Nut brand differ.

What do they look like?

Nut is the same Bluetooth tracker with the same basic features as Tile, but there are many differences between them, and they are significant. We reviewed two trackers of this brand - the second and third generations. They are the same size, close to the Tile Original and Tile Mate, but due to the tapering of the body towards the edges and more rounded corners, they appear smaller. There is no dust and moisture protection at all - in the cases of both Nuts there are quite large and uncovered holes for sound output. These trackers are also attached differently - there is no hole for a key ring, but you can use a thin cord - it comes complete with Nut 3. Nut 2, unlike Nut 3, comes without a strap, but is available with different case colors and is equipped with tape for gluing. By the way, the sound holes for both models are made at the end of the case, so they do not overlap when the key fob lies on a flat surface or is glued to something.

Packaging and components of Nut 2 and Nut 3:



Appearance of Nut 2 and Nut 3:

Comparison with Tile:

Both Nut models look more fragile than Tile and are easy to disassemble (the cases are assembled without glue, with latches). Moreover, the Nut 2 will have to be disassembled if you want to attach a strap to it (in the Nut 3 it is inserted without disassembly). Inside there are very few electronics and a lithium battery of the most popular CR2032 format, which lasts “only” for six months. But it is easy to replace.

The button on Nut 3 is marked on the body with a three-dimensional pattern, while on Nut 2 it is designed as a separate element. Led indicator(for Nut 2 - around the button, for Nut 3 - hidden) complements sound signal and confirms the button press, but for searching it is practically useless (it will only help in the dark, if the tracker is not covered with anything). Tile, for example, has no indicator lights at all.

What can they do?

Nut's app is not as beautiful and stylish as the Tile App, but it is interesting in its own way. And also, alas, not Russified.

By adding your Nut friends, you can allow them to see your phone's coordinates. The phone itself is not displayed in the list of trackers, but you can call it using the button on the key fob in the same way. To do this, Nut first needs to be Bind, assigned to one of 6 categories and given a meaningful name (Cyrillic is supported).

Selecting a tracker in the list opens a page for its status and settings. For each keychain, you can add a photo (take it with a camera or select it from your smartphone’s gallery) and turn the sound signal on or off.

Unlike Tile, Nut key fobs have one standard melody, but for your phone you can choose one of nine ringtones and set the duration of its playback - from 3 to 60 seconds. More than half of the melodies are sharp, alarming: car alarms, fire and police sirens, and the like. Several times I happened to frighten those around me with these sounds, and once I was even frightened myself. This approach to notifications has its own logic, and it differs from the logic of Tile - tiles are designed to find lost things, and Nut is primarily designed to not lose them. As soon as you move away from the tracker and the connection with it is broken, the phone persistently warns you about this - with sound, a pop-up window on the screen, and a standard system notification.

The key fob itself also plays a melody, but since the signal can attract unnecessary attention to a forgotten item, it is possible to turn it off. This operating mode is called Anti-Loss, it is turned on by default and is perfect for things that you go out with or travel with and that are likely to be lost or stolen - that is, for a bag, wallet, tablet , photo/video cameras, etc. Just remember that the volume of the signal when the connection with the tracker is broken is adjusted along with the volume of the phone call. That is, if you set your phone to silent mode, then the Nut application will not bother you.

For things that do not leave the apartment or house, it makes sense to enable the Find-it Mode. In this mode, the application does not bother the user with messages about the connection being broken and restored, but if necessary, it will help to find an item with an attached tracker. This mode is suitable, for example, for a remote control remote control TV, however, for this it is better to glue a miniature Nut mini to it. You can call the key fob using the Call button, while simultaneously tracking the distance to it using the signal strength indicator, and also view its location on the map. These functions also work in Anti-loss mode.

If you lose an item with a Nut tracker, you can view its last known location, get directions to this place and, if it is not lost there, put it on the wanted list (Declare loss function), asking for help from the community of Nut owners. As with the lost Tile tracker, any smartphone with installed application Nut can detect your tracker and send you its coordinates, without user intervention, without revealing the location of your things to strangers. If the item is suddenly found, the ad can be canceled. If you want to include friends from Twitter or Facebook in the search, you will have to do it “manually” - the Nut application allows you to ask for help only from users of the Chinese social network WeChat. Unlike Tile, here you can also set a search area, which, according to the authors of the application, increases the search efficiency (maximum radius is 5 km from the last known location).

What else can they do?

The Nut keychain can be made available to other Nut accounts (maximum 20) in two ways - by scanning the QR code from the display of your smartphone or by sending a link. This feature is called Group Find and only works in Find-it Mode. Moreover, you can exit this mode only by canceling shared access for all users, which is not very convenient.

The application provides a silent mode (Silent Mode), which can be turned on automatically in safe places (when the phone is connected to a trusted point Wi-Fi access, for example, home or office), as well as at safe times - according to a schedule (for example, at night). You can also enable silent mode for a certain period of time (Interim Silent Mode), in this case on home page application displays a timer.

There is one additional function, as a tracker location history with address and time. Its usefulness is questionable - after all, the position is still determined by the smartphone, and its history of movements is already available in the Google account. Possibly based on this feature in combination with shared access you can create a tracker inexpensive system monitoring movements, for example, of a company car or cargo accompanied by a courier. Or a time tracking system in a small office (one or more trackers at the entrance, employees have an app on their smartphones). But somehow this is all frivolous. Maybe someone will suggest a really interesting application in the comments?

Any of the trackers can be removed from the application. When the key fob is connected, deleting it frees it from being tied to this account - now another user can connect and use it. That is, Nut (unlike Tile) can be sold, donated or given for temporary use without contacting support. If you delete a tracker that is currently unavailable, you can only connect it again to your account.

New versions software trackers are installed directly from the application:

How do they work?

Both Nut trackers performed well. The signal about a connection failure comes at a distance of 30–40 meters (on the street without obstacles), aggressive ringtones for your phone help you not to miss this moment. Restoring the connection, like with Tile, takes a minute or two - if you heard an alarm and returned for forgotten things, a connection notification will sound very close to them. Silent mode and search mode work as intended, the application is stable (there was only one crash during the entire testing period).

How much are?

At the time of completion of the review in the iLounge store, Nut 2 cost 458 UAH, Nut 3 - 608 UAH, Nut mini - 371 UAH.

For those who want to know more

After installing the Tile and Nut applications on the smartphone, its autonomy naturally deteriorated. On my own Bluetooth version 4.0 LE has very low power consumption and has little effect on the phone's operating time, but a constantly turned on GPS adapter that periodically determines its position significantly reduces the operating time without recharging. Instead of two and a half days of work without trackers, the Lenovo P2 battery lasted a day and another 7 hours, tracking five connected devices (three Tile and two Nut). However, if you use only one of the applications, it will not be so noticeable.

Applications also use data transfer, but this is not a cause for concern. The traffic generated during testing is small, and mostly generated by studying online help and testing functions like sharing trackers and putting them on the wanted list, and in normal operation it will be completely insignificant. As can be seen from the screenshots, the Tile application consumes noticeably more memory and traffic per connected device than Nut, and in terms of battery consumption they have parity - 1% for each tracker (power consumption is not taken into account here GPS module, for which the smartphone does not provide separate statistics).

On the manufacturer's website there is a mention of problems connecting Tile with smartphones on Android versions 6.0.x. In 6.0.1, these problems seem to have been resolved, but the manufacturer Tile guarantees normal operation only with Nexus smartphones; for others, the question is open - it is unrealistic to test all Android devices. There were no problems with Lenovo P2 (Android 6.0.1 and 7.0) and LG G3s (Android 5.0).

The bottom line is. So after all - Tile or Nut?

Unlike Tile trackers, which were clearly created with an eye on owners of Apple smartphones and tablets, Nut is closer in spirit to Android users. Such associations immediately arose in me thanks to the design of the trackers, and were later reinforced by the nuances of use. Accordingly, comparing them is somewhat reminiscent of the battle “iOS vs Android”. I liked the Nut trackers more (well, yes, I have Android) due to the presence of an active Anti-loss mode, and also because they are more accessible, more practical, and the user can manage them at his own discretion, without turning to the “big brother”.
