@serkam Did you manage to get anywhere with this? I have the same requirement and after hours of searching have drawn a blank. I have found a few Arduino libraries but nothing using the native esp IDF.

Hi Both, Any chance you can post the full code that you used to get this working? I have tried both of your suggestions by modifying the esp example code and still can't get it working. @gleiva when I did your suggestion, I got a core dump when calling clear_sim800_pwkey @bharath when I did your sug...

Hi

Just came across this. Which module did you buy and did you get this working? I have a SIM800L but that seems to only cater for 2G. Have been looking for a 4G module but no success yet. Also, were the AT commands proprietary for your module?

Thanks

Lee.

Hi

Haven't had any responses on this so thought I would give it one more try

thanks

Hi all, I have been doing some tests on the GPIOs to see how the various settings affect them. The tests use 3 pins - 32 set to GPIO_MODE_INPUT and GPIO_PULLUP_ONLY - 35 set to GPIO_MODE_INPUT and GPIO_FLOATING (input only pin with no pull up/ down circuitry) - 33 set to GPIO_MODE_INPUT and GPIO_FLO...

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

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.

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 ...

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...

Hi all

I have found some articles online talking about using a pi as a JTAG debugger. It looks like this can be used to real time debug an ESP32. Has anyone actually got it working? Anyone know of a good tutorial?

Thanks

Lee.
