@Vinny Thanks that does! So I made a new wire and it worked! It turns out my issue was that because I created a custom USB 2.0 to 4 pin JST connector I had too much exposed wiring. USB apparently requires a ton of shielding around all the wires to work which I did not know until now. Thanks for all the help with clarification

One more thing came to mind. I realize that I can only get any sort of connection between the pi and module if I power the module via the 5V pin on the pi. The only thing I can think of is that the usb connector and the 5V DCin share a common ground which may create a better connection?

Thanks @Vinny and @Chad-Sweet for responding! I'll try to give you guys some more information so hopefully this makes more sense.

I used the enable script and ran all the commands on ubuntu 20.04 on the pi. I was able to establish a connection momentarily by seeing the device come up with lsusb. I had connection to the internet for a little while, but then the connection became very spotty (the two downstream LEDs would go on and off) and eventually to the point where the device would not even show up at all with lsusb.

I'm realizing now from your reply @Vinny that this issue is much more likely to be with the enumeration of the pi with the module as I didn't realize that the LEDs were indicators of connection as opposed to power supply.

To answer your questions in order @Vinny :

1. Yes, I am using the standalone board and I am referring to the 2-pin J3 connector on the back currently powered by the Rpi 5v pinout (I have also tried using a different 5V power source outside of the Pi)

2. Yes, I am using the J4 4-pin to connect to the Rpi

3. It very well could be a bad USB cable, so I will try to create a new one and see if that helps, but I have already tried with two different cables and had the same problem, so I'm not sure

Let me know if this brings up anything yall can think of. But thanks a ton for the help!

Hi,
I have setup the V2 LTE module with a rpi4. I connected the module to the pi through the upstream usb port on the module. I am powering the entire module with 5v DC power through the back connector, but i'm only seeing the three LEDs by the upstrem usb illuminate. The other LEDs (by the downstream ports illuminate occasionally). I'm guessing the module is not getting enough power? Are the usb ports powered separately from the rest of the board?

Great thank you!

Hi,
I was wondering where to find documentation for connecting the LTE v2 modem to a raspberry pi 4. I'm looking for pin connections as well as a guide for configuring. I am running ubuntu 20.04 on the Rpi currently.

Thanks so much!! This is super easy solution

Is there a simple way to start a bash script on boot of the device? I'm finding that common linux solutions aren't working on yocto.

Thanks!

Hi,
I'm trying to stream a camera image from my OV7251A36 camera to QGC. It is connected into port J4 and i ran voxl-configure-camera to option 2. However, when I run voxl-streamer it can't seem to start the streaming service. The terminal stops at: Using configuration file /etc/modalai/voxl-streamer.conf. Is there a step I'm missing?

Thanks!

I see that now! Thanks for the reply. Would it be possible to swap our standalone for the one that connects to the voxl?

My v2 modem is missing the connector to plug into the voxl j13 slot. I'm wondering where I would buy this connector and why it is missing in the board I bought?

Ok great! Thanks for the info!

Hi all,
I'm trying to setup a drone network using one ground station (laptop running QGC) and multiple drones with voxl computers. Is it possible to use the 4G LTE of the voxl to communicate multiple drones to one ground station?
