      @Jerry-Lin Yeah it doesn't seem as though the quectel modem is being detected at all. Can you post a picture of your setup as a sanity check?

        Sure,

        I didn't touch anything except for opening the cover, unscrewing the nuts and inserting the SIM card.

          @Jerry-Lin Are you sure that the add-on board is fully seated onto the VOXL 2? There are two connectors that need to be fully seated

            Hi @tom I am not sure and don't know how.

            Can you show me some pictures so I can have the clue which modules are needed take apart for checking and making sure.

              @Jerry-Lin If you looks at the diagram here: https://docs.modalai.com/5G-Modem-datasheet/#block-diagrams
              both J4 and J2 need to fully inserted into J5 and J3 of VOXL 2, seen here: https://docs.modalai.com/voxl2-connectors/#connector-callouts

                Super cool, after all unscrewed and the modem taken out, I saw the connectors. Knowing how they connect, I pressed hard to make sure fully seated and the qmidevice_detect failed went away with the WiFi working!!!

                The output of lsusb looks more devices now:

                voxl2:~$ lsusb
                Bus 002 Device 003: ID 2c7c:0800

                The output of quectel-CM is now totally different:

                However, it takes forever to finish. I googled around my AT&T APN, it looks right using nxtgenphone:

                If you have an:
                LTE device: Set your settings to NXTGENPHONE
                Data device: Set your settings to Broadband
                5G Smartphone: Set your settings to ENHANCEDPHONE

                Not sure what is going wrong this time.

                  Hi @Jerry-Lin
                  Glad Tom was able to help you and you are making progress.
                  For future note, please re-install the nut hardware on these screws or the boards can become separated again leading to more failures.
                  26444f95-d369-4be9-82a7-78e56262609e-image.png
                  Please be careful to ensure they do not contact any of the circuit components on the PCB.
                  Thanks!

                    @Jerry-Lin Awesome seems as though the hardware is working as expected now. I can't tell you what the correct APN is for your network, it very much depends on your plan, provider, etc. It's possible you need a SIM card specifically for IOT devices from your carrier

                      Sure, will do.

                      Sorry that I was trying to insert the SIM card and realized unable to do it unless lifting the modem module. After inserting the SIM card, I didn't push hard worrying breaking anything because the drone is super expensive.

                      Thanks to Tom for helping me understand how the modules are connected. I think inserting the SIM card is a very frequent activity and it would be nice to make it very accessible by a hole like others on the side. It took me hours to figure out how to access the SIM card socket. Anyway, now I learned how to secure the connections and not a problem for me anymore.

                      BTW, any idea about my last "timeout and trying forever" issue? I have tried two SIM cards without a success.

                        @tom said in Quectel 5G-Modem doesn't work at all:

                        It's possible you need a SIM card specifically for IOT devices from your carrier

                        So, did you mean normal phone SIM cards are not compatible with the Quectel modem and the "5G LTE" is not the same protocol our phones use as advertised "Connectivity: 4G/5G"?

                        Then, what are requirements should I provide to my carrier (located in Pennsylvania, USA) for this kind of SIM card to get the drone Internet access?

                          @Jerry-Lin They can be, it just depends on the carrier. We always test here with Google Fi IoT SIM cards, they're super easy to setup and cheap

                            Cool, my carriers are AT&T and Xfinity Mobile. What I should I mention to them for my application? Just IoT or any specs that you know about?

                            So, the log:

                            voxl2:~$ quectel-CM -s nxtgenphone

                            looks a SIM card issue to you? Or what else (e.g. commands or wiring) can I try to get 5G connected?

                              @Jerry-Lin I would mention IOT as well as the modem you're using "Quectel RM502Q-AE". I know when I was first working with this modem that some carriers didn't yet support but that was a long time ago so I'm guessing that has changed

                                OK, will get to carries to see if I can move forward with the existing SIM cards. If not, will try Google Fi IoT SIM cards.

                                Thanks for the advice!!!

                                  • checked with an AT&T store and they provide SIM card for phone only.
                                  • then googled around and found several attempts using Quectel MODEM with AT&T SIM card and AT commands were used for debugging.
                                  • searched in ModalAI Forum and found some AT commands for the model.
                                  • tried but got only ERROR

                                    voxl2:~$ echo -ne "AT+QNWPREFCFG="mode_pref",LTE:NR5G\r" | busybox microcom /dev/ttyUSB2

                                  • I was not sure about the impact of Too few arguments error, though.

                                  Well, with an IP address, I tried to:

                                  • ping
                                  • ssh

                                  Unfortunately only responded with timeout messages.
                                  Wondering if I really have the Internet access, I did ifconfig wlan0 down and the ping google.com from voxl. It was still responded !!!

                                  Hmm, how about continue Connecting to QGC over 5G instructions?

                                  • With Tailscale VPN installed, I was able to ssh to the drone using the VPN IP address!!!
                                  • With QGroundControl setup, I was able to see the drone statuses and statistics using the VPN IP address!!!

                                  That means I can control the drone even it is hundreds of miles away!!!

                                  Millions of thanks for great help @tom and @Vinny !!!!!!!!!!!

                                  Still with Too few arguments error, I am not sure how good the 4G/5G connection would be. Will experiment more to figure out. However, if you guys know anything can be improved, please let me know.

                                    @Jerry-Lin You can ignore the "Too few arguments" message, that comes from lower down in the quectel driver, it shouldn't cause any issues.

                                    Glad to hear things are working! It may take some routing changes in order for both wifi and 5g to work at the same time.

                                        BTW, what are the routing changes suggested? Do I need to execute any commands? Or, do they happen automatically by some code or scripts?

                                          @Jerry-Lin Not something I can provide too much data on as I don't have a ton of linux network routing experience. But from what I understand you can use ip route to see how your network traffic is being routed for each network interface.

                                          You can also change the default route via something like sudo ip route change default ..... (don't know the exact command format) might take some research.
