    — In this video, I show all the ways to connect over the network to a Raspberry or Radxa, and therefore to the Uas4g5gLte program. Everything is simple, and if you follow exactly the steps I show, you will not encounter any connection problems.

  • Network Connections:

   — After you have written the image to the SD card and booted your Raspberry or Radxa board, the first option is to connect to the hotspot created by Uas4g5gLte using the password 12345abcde, then open in your browser the address: 192.168.77.1:3000/uaslte. You will reach the program’s graphical interface.

    — There is also another option that does not require using the created hotspot, but your board must have an Ethernet port. Simply connect a LAN network cable between your Raspberry or Radxa board and your router. In this case, you can access the graphical interface in the browser after you find out the IP address assigned by your router to the board. You can find it easily by logging into your router’s menu and looking for the device named Uas4g5gLte. Note the IP and open it in the browser in the form your_router_ip:3000/uaslte. For example, if the IP assigned by the router is 192.168.2.167, you will open in the browser: 192.168.2.167:3000/uaslte.

    — The same method applies when you connect to your personal Wi-Fi: in this case as well, you must check in your router what IP address was assigned to your Raspberry or Radxa device, then open the graphical interface in the browser using that IP, just like in the LAN connection case.

    — Be careful to enter the correct Wi-Fi SSID and password, because if you enter them incorrectly, you will no longer be able to return to Hotspot mode to enter them again. The only options then are to connect via LAN or to reflash the program image to the SD card and repeat the procedure.

  •  A few words about the program and how it works (main points)
1) Internet requirement (UI 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 UI interface.
 
 2) Automatic UI updates at every boot (no manual UI downloads for you)
    – Any update I make to this interface is automatically uploaded to your boards when they boot,
      making my work easier so I don’t have to create updates that you always have to download.
    – So, for an easy software update, you only need to boot your board, because it automatically pulls the latest version from the server.
 
 3) Major updates are manual and rare
    – Heavier and more complex updates are done manually by you from the UPDATE FIRMWARE tab, and they are more rare.
 
 4) Internet at startup is normal / not a problem for 4G usage
    – 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.
 
 5) If UI doesn’t appear in 1 minute, check modem + internet + LTE LED
    – If the UI 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.
 
 6) 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.
