GSM Library

[leenowell]

Hi All,

I have ordered an ESP32 development board which has a GSM module. I have been looking for a good recently updated GSM library so I can send/ receive SMS as well as dabble with voice calling. I have seen TinyGSM seems to be popular on the Arduino forums but it doesn't support receiving SMS. I have seen LilyGO but that was last updated 2 years ago. Anyone have any suggestions?

thanks

Lee.

Hello lee,
I am working with a TTGO T-Call SIM800L ESP32 Board and pppos_client (ESP-IDF).

Thanks MarkSoft. I had seen a reference to PPPOS somewhere but didn't know what it was and couldn't see how it was used to drive the modem.

I just checked the IDF documentation to see how to use it to send an SMS and can't find any reference to it. I suspect it is hidden in one of the sections. Any chance you could point me in the right direction please?

Thanks again

Lee.

Hi all

Does anyone have any sample code for sending an SMS using PPOS? I am using the same board you mentiion so any help appreciated.

I have also seen libGSM mentioned but can't find an active git project for it on ESP 32. This might be another option ?

Thanks

Lee.

Hi,

Anyone any thoughts? I have seen a libGSM as part of the PPPOS which seems good but doesn't look like it is maintained. Am a little stuck now so would appreciate any pointers in the right direction.

thanks

Lee.

Hi @leenowell,

Apologies, I realize that this discussion was opened years ago, but I thought I would reply incase you or anyone else are still looking for a solution.

LibGSM has officially been rereleased and now supports development in any compatible C/C++ compilers.

LibGSM provides the SMS Read module to trail for free (no license required). You can download the LibGSM Code Generator on the eiTech Systems website: https://eitech.systems/libgsm-gsm-library/

The LibGSM Code Generator is a Windows Desktop application that automatically generates all the required setup code to get a user started as quick as possible. The application also includes example projects for each module. If you would like to see the application in action, you can see this on eiTech Systems YouTube channel: https://www.youtube.com/@eiTechSystems
