Product Description

Why Choose the NEXAS Nexlink OBD2 Scanner Bluetooth 5.0?

Tired of the limitations of wired OBD2 devices? Want to try out more features with minimal cost? If you're into DIY car repairs, then it's time to check out this Bluetooth diagnostic scan tool that integrates dozens of third-party apps into one. The NEXAS Nexlink is a powerful OBD2 Bluetooth adapter that pairs the scanner with your smartphone or tablet via Bluetooth, allowing you to turn your device into an advanced car diagnostic tool. It provides real-time access to vehicle data and diagnostic information without the need for additional screens or displays. Compact and portable, it can be easily carried into the car or stored in the glove compartment for convenient, on-the-go use, making it an excellent tool for automotive enthusiasts and everyday drivers. (The app's features depend on the developer, and some may require payment. If you're interested in using a particular app, it's a good idea to search in advance or check the manual to understand the app's features and compatibility, or ask questions on this page.)

  • Latest Bluetooth 5.0 Version: We have upgraded from the old Bluetooth 4.0 to the latest 5.0 version, resolving issues with weak signals and frequent disconnections. This ensures faster and more stable connections, with a tested signal range of up to 100 meters. (Due to its easy connectivity, it is recommended to unplug the adapter when not in use.)

It also offers HybridAssistant, providing simple and quick access to all relevant HSD information for Toyota, allowing users to view internal parameters of the HSD engine to optimize fuel efficiency.
  • Check Transmission Temperature: This is a feature that other OBD2 scanners do not support, but the NEXAS Nexlink can do it. If you have a Toyota Sienna, you can use apps like "Car Scanner," "Torque Pro," "OBD FUSION," and "DashCommand" to perform regular diagnostics on the engine, transmission, and other modules and data for this vehicle. Before use, please ensure you understand the app's capabilities, compatibility, and device compatibility. (Generally, OBD engine diagnostics are free, but additional features or special functions for other systems may be available for a fee within the app, such as OBD FUSION. However, CARISTA, FORSCAN are all completely free.)
  • AlfaOBD APP Choice: Specifically designed for Fiat Chrysler Automobiles (FCA), it is suitable for 1994-2021 Fiat/Alfa Romeo/Lancia vehicles and 2005-2021 Chrysler/Dodge/Ram/Jeep vehicles. It allows users to read and clear fault codes, monitor real-time data, perform various diagnostic tests, program and configure vehicle control units, and adjust specific vehicle parameters.
  • Unique Motorcycle and Automotive Diagnostics in One: The Nexlink OBD2 scanner diagnostic tool supports two motorcycle diagnostic applications: Motoscan and TuneECU (Android only). It is compatible with most BMW motorcycles (C, F, G, K, R, S, and Husqvarna series) with version 1.66 or higher, as well as Triumph, Aprilia, Benelli, Ducati & Moto Guzzi, Morini, Gilera, Husqvarna, KTM, BMW & CCM motorcycles.

    Genuine Elm327, Works, has minor assembly issues but it's the only BT 5.0 adapter I found.
    4 Stars
    Genuine Elm327, Works, has minor assembly issues but it's the only BT 5.0 adapter I found.
    This NEXAS NexLink OBD2 adapter does work and does what is advertised. It does have a genuine elm327 v2.x (as stated by others), please see pics. It also does contain a Bluetooth 5.0 module (BM78SPP05NC2) but based on its datasheet you cannot interact with it through the UART path to set PIN or the options.The look of the unit is good, fitment is tight (very tight seems), plug fitment is tight/good.Now with all this said, why did I remove a star…well look at the pictures.See if you go through all the reviews you’ll see a few that talked about sudden failures, well I read those before I bought and decided (since it was sold at a discount during the holiday season) that I’d take mine apart to see what could be the issue, before I dared plug it into my car.I also checked the connection between the battery and ground pins on the adapter with a multimeter, both ohms and diode mode tests were good. So it’s not shorted from the factory.To open the unit, take a flat-bladed screwdriver and place some tape on the edge, put the flat blade on the seam and push hard into the plastic bottom part of the seam (black obd2 connector to your left). If you push hard just under the seam and the clip will start to separate, then you can get into the seam and twist your blade. It’s all clips, no screws, or adhesive.You can see it open in my attached pictures.Now take a good look at them, you’ll see a glaring assembly issue. There are two circuit boards (PCBs) and they connect at by forming a “T” with solder. Theses tracks are both communication and structural.Well as you can clearly see from the pictures, some of these “joints” are very poor, like a glancing touch of solder. Please note, not ALL pins have tracks that are meant to be connected! So only tracks that meet at both PCBs were supposed to be soldered, same for pins not soldered.Now inside a car, there is vibration and so some of these could break very easily. On top of that one of the worst (because it’s hidden under components) was (Pin 16) the 12V incoming power connection! That breaks…well…no more power.I have pics of before and after my repair. The most critical is well hidden (Pin 16) so I had to carefully sneak into the corner to wick and resolder it.Afterwards it’s much better, much stronger, and when tested it in my car, it worked just fine.So at the end of all this, what did all this accomplish? Well, for one now the merchant knows there is an assembly issue (final assembly only, board soldering seemed good). Also the buyers know as well that if your unit “dies” then likely it’s just a cracked solder joint and can be repaired (you likely don’t need to throw it away).I wish this didn’t use a common Bluetooth pairing PIN, but whatever. Also for people who say it’s slow, well…I guess you’re right. The Bluetooth chip datasheet claims the LE data rate will NEVER exceed 7 kbps…that’s SLOWER than a 9600 baud serial connection. On top of that (unless it’s using a 1 Mbps internal UART connection…which I doubt) the datasheet claims that if the internal UART is using 115,200 baud with a traditional BR/EDR connection it will never be higher than 10 kbps, which is basically still as fast as 9600. Now this can be a good or bad thing, for people trying to push the comms to max and hope their ECU doesn’t miss a deadline…this is VERY slow, most people would want at least 38,400 baud or maybe 115,200 baud. However at those speeds you need better handshake/flow control and you need to be careful not to overwhelm the ECU of the car while driving. But using basically 9,600 is so slow you cannot overwhelm the ECU and you often don’t need special “chunking” to read the serial port data due to speed mismatches for the ECU reply to the serial poll/trigger rate.But that means…once you go beyond maybe two simple gauges…you’re going too slow for anything approaching real time. So be aware that this isn’t for those wanting 5-7 real-time gauges. I wanted more like temps, gear position, and fuel level and such…not data that needs fast polling, so I’m okay. Boost and pressure and RPM…go to USB or serial…not wireless. It’s not fast enough (for a reason).Can I recommend this product? Well, if you want better encryption, this really is the only one, regardless of the assembly issues.I’m certainly satisfied with the product, especially for the price. So I guess, now that you know all this, you can make a better informed decision. Love the color by way…really what drew me to it.

    4.0 out of 5 stars Genuine Elm327, Works, has minor assembly issues but it's the only BT 5.0 adapter I found.
    Reviewed in the United States on February 1, 2023
    This NEXAS NexLink OBD2 adapter does work and does what is advertised. It does have a genuine elm327 v2.x (as stated by others), please see pics. It also does contain a Bluetooth 5.0 module (BM78SPP05NC2) but based on its datasheet you cannot interact with it through the UART path to set PIN or the options.

    The look of the unit is good, fitment is tight (very tight seems), plug fitment is tight/good.

    Now with all this said, why did I remove a star…well look at the pictures.

    See if you go through all the reviews you’ll see a few that talked about sudden failures, well I read those before I bought and decided (since it was sold at a discount during the holiday season) that I’d take mine apart to see what could be the issue, before I dared plug it into my car.

    I also checked the connection between the battery and ground pins on the adapter with a multimeter, both ohms and diode mode tests were good. So it’s not shorted from the factory.

    To open the unit, take a flat-bladed screwdriver and place some tape on the edge, put the flat blade on the seam and push hard into the plastic bottom part of the seam (black obd2 connector to your left). If you push hard just under the seam and the clip will start to separate, then you can get into the seam and twist your blade. It’s all clips, no screws, or adhesive.

    You can see it open in my attached pictures.

    Now take a good look at them, you’ll see a glaring assembly issue. There are two circuit boards (PCBs) and they connect at by forming a “T” with solder. Theses tracks are both communication and structural.

    Well as you can clearly see from the pictures, some of these “joints” are very poor, like a glancing touch of solder. Please note, not ALL pins have tracks that are meant to be connected! So only tracks that meet at both PCBs were supposed to be soldered, same for pins not soldered.

    Now inside a car, there is vibration and so some of these could break very easily. On top of that one of the worst (because it’s hidden under components) was (Pin 16) the 12V incoming power connection! That breaks…well…no more power.

    I have pics of before and after my repair. The most critical is well hidden (Pin 16) so I had to carefully sneak into the corner to wick and resolder it.

    Afterwards it’s much better, much stronger, and when tested it in my car, it worked just fine.

    So at the end of all this, what did all this accomplish? Well, for one now the merchant knows there is an assembly issue (final assembly only, board soldering seemed good). Also the buyers know as well that if your unit “dies” then likely it’s just a cracked solder joint and can be repaired (you likely don’t need to throw it away).

    I wish this didn’t use a common Bluetooth pairing PIN, but whatever. Also for people who say it’s slow, well…I guess you’re right. The Bluetooth chip datasheet claims the LE data rate will NEVER exceed 7 kbps…that’s SLOWER than a 9600 baud serial connection. On top of that (unless it’s using a 1 Mbps internal UART connection…which I doubt) the datasheet claims that if the internal UART is using 115,200 baud with a traditional BR/EDR connection it will never be higher than 10 kbps, which is basically still as fast as 9600. Now this can be a good or bad thing, for people trying to push the comms to max and hope their ECU doesn’t miss a deadline…this is VERY slow, most people would want at least 38,400 baud or maybe 115,200 baud. However at those speeds you need better handshake/flow control and you need to be careful not to overwhelm the ECU of the car while driving. But using basically 9,600 is so slow you cannot overwhelm the ECU and you often don’t need special “chunking” to read the serial port data due to speed mismatches for the ECU reply to the serial poll/trigger rate.

    But that means…once you go beyond maybe two simple gauges…you’re going too slow for anything approaching real time. So be aware that this isn’t for those wanting 5-7 real-time gauges. I wanted more like temps, gear position, and fuel level and such…not data that needs fast polling, so I’m okay. Boost and pressure and RPM…go to USB or serial…not wireless. It’s not fast enough (for a reason).

    Can I recommend this product? Well, if you want better encryption, this really is the only one, regardless of the assembly issues.

    I’m certainly satisfied with the product, especially for the price. So I guess, now that you know all this, you can make a better informed decision. Love the color by way…really what drew me to it.
