Hi @Olivier-GASTÉ

It looks as though the instructions you are following are for the "v1" LTE modem while you are using a "v2" LTE modem.

Just yesterday I updated our modem documentation. Here is the updated documentation for getting your modem going: https://docs.modalai.com/lte-v2-modem-manual/

These instructions require the newest version of voxl-modem which can be downloaded directly from http://voxl-packages.modalai.com/stable/voxl-modem_0.10.0.ipk

In order to install this new ipk, you can use the following:

# On host pc adb push voxl-modem_0.10.0.ipk /home/root/ipk/ adb shell # On VOXL opkg install /home/root/ipk/voxl-modem_0.10.0.ipk

Once installed, you should be able to use the voxl-configure-modem script to get your modem up and running.

@Aldo-Castro-Freire thanks for the feedback, do you mind sharing the openVPN Client and Server versions you ended up using that worked?

We've tested using server v2.4.8, voxl-vpn (v2.1.3 inside that), and OpenVPN Connect ver 3.2.2 on Adroid.

Sounds good, thanks!

@Eric-Katzfey I figured that would be the case. Atm I am just letting it boot on it's own; the systemd service file is an idea that i will test and afterwards I will get back to you.

@Arrowtec This seems like it could be either a SIM card issue or an APN issue. Can you test the SIM card in another device such as a cellphone to confirm that it is functional? If it is, I would use voxl-configure-modem and confirm that you are using the correct APN in order to connect to the network.

@Arrowtec Okay this all looks normal, have you tested this SIM card in a different device to confirm that it is indeed functional?

We expect to have more product announcements later this summer around 5G

@Chuck-Bokath Are you using an LTE v1 or v2 modem? Are you using voxl-modem in order to connect to the network?

@vmassague Awesome!

@tom The crazy continues. The ATT sim card works at my home, though not in the office. I have an ATT phone, and it works at the office, though the data sim card does not. arrgh.

@RichieRich said in Which controller are you using in the LTE demo video?:

Thanks!

Thank you very much for sharing!

@modalab Thanks, starting my assembly and verifying parts. I didn't recall any antenna with the kit, will have to get some in the mail. Thanks for the reply

@Chad-Sweet Ok thanks for your time.

By default on all M0090 variants, all the transceiver/buffer circuits which take the 1.8V Kernel Debug UART to 3.3V TTL for J6 are DNI'd (not populated).
The only thing that can be done is to probe on raw circuit pad locations for TX and RX to get the signals at a 1.8V level.
Here are those snapshots to help guide you should you wish to pursue that route:

However, the ICs are located on the bottom side of the PCB, so when mated with Voxl2, you cannot probe directly, which would require soldering on wires to the PCB pads. That would likely violate any warranties on this specific PCB if you did that.

@Chad-Sweet My region operating bands in India are 4,30 and 1. All these bands match with modem since I was using the modem since past few months successfully. All of sudden it has stopped working.
What inference can we derive from above logs? My region code are getting fetched correctly but registration isn't happening for Sim cards. I have tried multiple sim cards as well but no success.
Can it be hardware issue?
Is there any way to factory reset modem?
How to debug this further?

@Henry-Cappel let me send an email to kick things off

@Eloi Hi Eloi,
We only support B key on that design and do not support any plug in adapters like your link.
There is strong certainty that it will not work.
B key vs A/E key is not just a pin block difference, but several electrical differences exist as well (voltage settings and port options).
B key is largely defined for modem devices which run on 1S "vbat" and A/E key devices largely for WiFi or I/O devices which run at 3.3V.

@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
