Project Description

B2316 is a GPS bracelet that uses the latest low-power Cat M1 & NB-IoT technology, fusion positioning technology and multiple sensor technologies, and a built-in IoT SIM card.

Including body temperature monitoring, heart rate and blood pressure report, SOS alarm, step counting, sleep statistics, indoor and outdoor positioning, Geo-fence, historical track query, etc. The data will be automatically reported to the server and mobile APP periodically.

The B2316 GPS bracelet is small, lightweight, deeply waterproof, and is suitable for all-weather wear. It can be used for monitoring in schools, prisons, nursing homes, factories, and hospitals.

3. FAQ

     1.  Why does B2316 Support eSIM only and the pluggable is unavailable?

    • The B2316 GPS Bracelet PCB size is limited and not enough space for NanoSIM (Nano-sim is the smallest pluggable sim), so eSIM is the only solution.

      2. What’s the Spec of eSIM and how to get the eSIM?


    • You can contact your local mobile operator to get the eSIM cards, or we can share some local operators for you.

     3. How to install the eSIM?

    • Send us your eSIM and we will arrange for the engineers to solder it to the PCB and config all info to make sure access to your Cat M1 or NB-IoT network is successful when you are ready for testing.
    • Of course, if you have hardware engineers who can change the eSIM by yourself,  we will share the video showing how to disassemble the unit (anyway there is a risk to destroy PCB).
    • For bulk orders, you need to send us the eSIM before production.

     4. The positioning is based on GPS+WiFi+BLE, this means there is a WiFi and  LBE transceiver is included in the bracelet?

    • Yes, the B2316 built-in WIFi chip can get the MAC and RSSI info for WiFi indoor locations.
    • It also supports BLE which can use for OTA and Bluetooth configuration.

     5. SOS button function?

    • SOS report to server/app(do  not support SMS and voice alert)
    • Device power ON/OFF

      6. Does this device support SMS and voice functions?

    • SMS is available on the CAT M1 network ( user sends the text command to tracker only)
    • SMS is unavailable on NB-IoT Network
    • The device does not support voice function (two-way communication).

      7. How to config the GPS bracelet tracker?

    • We will release the Bluetooth App that can config the device such as APN, IP/Port, network, working mode, report interval time, etc.

     8. Which protocol does the device support?

    • TCP/UDP

      9. Can I integrate the device with my own server?

    • Sure, our protocol is open and  Click here to download the protocol. After integrating the device will direct communication with your server and not report data to our server anymore.

10. Which Third Party Platforms are compatible with this CAT M1 & NB-IoT GPS tracker?

    • Currently, it only supports Traccar(port 5191) and gpsworx (port 6191), both of them have to use UDP protocol.
