Example code embedded modem Skywire

Projects General Guidance
1

Hi!

I have gotten myself a Niblelink/Skywire embedded modem, in the product description they said that they have "example code for arduino", but I have been searching for weeks now and can literally not find a single example, last resort was to ask ChatGpt but was just as useless as always :smiley:

Does anyone here have any experience with any embedded modem and hopefully a Skywire modem?

Thanks in advance!
Best regards Max

Most modems use a what is known as the AT command set.

Once you have the power supply to and serial connection sorted out, you can get started on figuring out the details.

Look for a data.sheet yo find the connection to the specific chipset.
e.g. SIMCOM or other manufacturer.

D you have a link to the product you purchased?

I have heard about the AT commands and some combinations of it to make the modem ready to do stuff like HTTP GET request, I have also read through some of the documentation to see which AT commands are available,

My goal now is to make myself an easy to use Wrapper/Library for myself so that I can use it very handy :slight_smile:

Here is the exact modem I have: NL-SW-LTE-TC1WWG NimbeLink, LLC | RF and Wireless | DigiKey

Here is the link to their official site, it is a little bit more useful and has better docs: https://www.airgain.com/products/4g-lte-cat-1-global/

I have a development shield for the Arduino Uno, it is a little bit unfortunate that I cannot find the example code.. but I have contacted the retailer and manufacturer to hopefully recive some information. But now i have to try and craft my own wrapper :slight_smile:

I’d suggest looking at the Adafruit FONA library to get started.
I haven’t heard of that brand modem, but a the AT command set is faitky standardised, I can almost guarantee it will get you started.

As you get more complex, I’m sure it will begin to stretch your skills.

See if you can find a manufacturers Application Note, or detailed data for that product. There may be a fotum somewhere - like stackexchange

Good luck.

The website you reference has the AT command set document (and much more) for that modem
