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,  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 configure 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. How about the BLE functions? 

    • BLE use for OTA Only
    • In the future will release the App for Bluetooth configuration(now do not support)

     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 send 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?

    • Use 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?

    • UDP (Jason format ) only

      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.

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

    • Currently, it only supports  GPSWox(port 6230) and Traccar (port 5230)

     11. Battery life(Backup is 160mA)

    • 80 hours every 5mins upload interval
    • 130 hours every 30mins upload interval
    • 360 hours every 60mins upload interval

     12. Can we design the software and you help design the hardware only?

    • For the OEM Service, it’s acceptable for us to design the hardware and you design the full software, we can open the Schematic diagram to your engineers for the software design, we just produce, assemble and test the tracker in our factory as the requirements.
    • We need to get more requirements in detail for your case, so we can give detailed solutions for the project. Of course, we can sign the NDA first.
