SIM7600A-H GPS Not Working

Hello,

My name is Ronak Patel. And, I am working on my masters project.

In my project I want device location for that I am using SIM7600A-H 4g HAT module on top of Raspberry Pi 400 kit.

I am able to send SMS that functionality is working fine, But the location service is not working, I am not able to power on any functionality (GPRS or CGNSPWR) with AT command.

I tried below commands and getting error message on each one

  • AT+CGPSCOLD
  • AT+CGPSHOT
  • AT+CGPS=1
  • AT+CGNSPWR=1

On every command related to position I am getting an error message.

I am running out of time, Can you please help me with this?

Thank you in advance and looking forward to hearing from you.

Regards,

Ronak

Hi @ronakpatel3007 and welcome to our forum.

For this product, please refer to this Wiki page: SIM7600CE-T/E-H/A-H/SA-H/G-H 4G Modules - Waveshare Wiki

I see there is a GPS positioning demo code. Did you test this?

Thank you.

Hello @igor_X Thank you for sharing this input yes I tried this link but I had to change mode 2 in GPS. It was 1 by default and it was not working in my case after setting mode 2 it is working.

Now, I have one more question and seeking your help one more time.
I am able to send SMS through this module but I want to send MMS (a photo Image with SSM), Waveshare wiki has not has this information.

Can you please guide me in this one?
Looking to hearing from you.

Ronak

Sorry @ronakpatel3007

I don’t have experience with this and I am not sure if sending MMS is possible.
