Activate Uas4g5gLte:

    — Once you have ensured that you have an internet connection—by first testing the ping response in the interface—you can press the Activate button. So it is very important to first test the internet connection by pressing the Internet Ping button.

    — Important: never press the Activate button if you do not have internet, otherwise you won’t be able to activate the program and you will have to reflash the image and repeat the procedure.

Internet Connection Source:

    — Before connecting to the program interface, you need to know that you choose which device will provide internet to your Raspberry or Radxa board. You have three options:

  1. LAN — connect a cable between your router and your board’s Ethernet port (if the board has one).

  2. 4G/5G LTE USB modem — in this case, plug it in before powering on the board.

  3. WFi connection —  after you access the program interface by connecting to the Uas_Lte hotspot, you can connect to your own Wi-Fi by entering the SSID and password, then pressing the SET button. In this last case, Uas4g5glte will switch in about 5 seconds to your router’s Wi-Fi connection, making the Uas_Lte hotspot unavailable.

Important: if you enter the wrong SSID or password, you will only be able to access the device via LAN. If you don’t have LAN available, reflash the image and repeat the procedure, entering the correct Wi-Fi connection details.

  • Important aspect:
    — Internet requirement on STARTUP (PROGRAM INTERFACE will downloaded from cloud at startup)
    — You must know that the program runs only if you have internet, because its graphical interface is downloaded at startup from a cloud server.
    — This happens so the program is always updated with the newest available program interfaces.
    — So as long as you have internet at the moment the program starts, everything is fine,
      and it’s normal to have it because you cannot use the program in 4G mode otherwise, so this is not a problem.
 
 A) IF PROGRAM INTERFACE doesn’t appear in 1 minute, check modem + internet + LTE LED
    — IF THE  PROGRAM INTERFACE does not appear in a maximum of 1 minute (even though normally it appears in 15–20 seconds after startup),
      check if you have internet, if the modem is plugged into the board,
      and if the green or blue LED that indicates the 4G LTE connection is solid.
    — It must not blink; it must be solid in the case of Huawei modems.
 
 B) Modem can be plugged in later (not mandatory before boot)
    — You can plug the modem into the board even later; it is not a necessary condition to have it plugged in before powering on the Raspberry or RADXA board.
    — As soon as the modem starts and provides internet, the program downloads the interface and displays it.
 

    — If you are not using the Uas_Lte hotspot and you want to access the program interface via LAN, or if you have successfully connected to your own personal Wi-Fi access point, then the program’s access address will no longer be 192.168.77.1:3000/uaslte. In these cases, you must log into your router’s menu, check which devices are connected, identify the Uas4g5gLte device, and see what IP address your router assigned to your Raspberry or Radxa board.

    — There are other ways to find this IP (for example, using an IP scanner), but the router method is simpler and is usually the easiest option—as long as you know the username and password to access your router.

    — So, for example, if the router assigned the IP 192.168.2.33, then you will open in your browser: 192.168.2.33:3000/uaslte. If a different IP was assigned, use that IP instead. I think things are clear and fairly simple.
