Jetson Nano with SIM7600G HAT Module

ziya.5757 · September 15, 2021, 9:35am

Hi All,

Has anyone worked on integrating SIM7600G 4G module with Jetson Nano.?
I tried all available methods, can anyone suggest me the hardware connection and dependency libraries for the module to work properly.

# Setup the Waveshare SIM7600G for Jetson Nano

This guide is heavily adapted from the guide published on the waveshare site, available [here](https://www.waveshare.com/wiki/SIM7600G-H_4G_for_Jetson_Nano).

Notes: There seem to be numerous errors and omissions in the instructions as provided by Waveshare. This guide documents my process so that others may avoid many wasted hours of effort. It turns out that you don't need `udhcpc` if you already have `dhclient` installed. You also don't need `minicom` or `screen`. There is a way to send and view serial using two terminal windows and built in commands `cat` and `echo`.

## Assumptions

* Your host system is either Linux or OSX
* High degree of comfort with the commandline (i.e. compiling from source)

## Requirements

* Jetson Nano B01
* Waveshare SIM7600G-H Hat for Jetson Nano
* Activated SIM with talk/text/data (Mint is tested and works)
* High-speed internet connection (for host and Jetson)

## Hardware Setup

I tried above method but failed
Actually I want to run AT Commands but unable to send the AT Commands.
Thanks in Advance.

I know nothing about this particular hardware or software, but AT commands are sent via a serial UART. In the URL you gave it uses “/dev/ttyUSB2”. This would be an example of a serial UART, probably one with an FTDI chipset. Are you using the correct device special file?

If you run “dmesg --follow” from the system which has the USB cable on it, and then plug the cable in, you should see new log lines naming the particular device special file. This would be what you use for talking to your device from minicom from their example.

Note that FTDI is generally available without any work on most of Linux. If the name is different, e.g., if it is a CDC chipset, then perhaps you need a driver. Knowing what the dmesg is upon plugin, and knowing what error you get, would probably help. Like I said, I do not know anything about your device, but serial UART communications is more or less standardized.
