The result was still the same.
I tried the latest voxl-modem and still no luck.
I purchased Sentinel with 5G LTE modem without touching anything. I double checked the Quectel modem after inserting the SIM and confirmed it is secured as before.
Can anybody help resolve this issue?

@Jerry-Lin What do you see with
lsusb
andlsusb -t
? -
Hi @tom, here are the outputs:

This post is deleted! -
The weird thing is every time I insert the SIM card, my WiFi will be gone without even the blue flash light from the WiFi module.
Then, it took me long to get WiFi back by reconnecting the wire, touching around Quectel module, restarting
dhcpcd
and disablingvoxl-modem
, anything I can think of related towlan0
.After having WiFi,
lsusb
would output:Bus 002 Device 002: ID 0424:5744 Standard Microsystems Corp. Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 0424:2740 Standard Microsystems Corp.

While having more USB devices, I tried
voxl-configure-modem
without the SIM card, I still got$ quectel-CM -s nxtgenphone [09-08_07:06:58:832] Quectel_QConnectManager_Linux_V1.6.0.24 [09-08_07:06:58:832] network interface '' or qmidev '' is not exist [09-08_07:06:58:832] qmidevice_detect failed [09-08_07:06:58:833] qmidevice_detect failed
-
@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 Bus 002 Device 002: ID 0424:5744 Standard Microsystems Corp.

The output of

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

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!!!
-
I
- 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

Unfortunately only responded with timeout messages.
Wondering if I really have the Internet access, I didifconfig wlan0 down
and theping google.com
fromvoxl
. 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.
