HI,
I´m trying to implement the project Send SMS “Hello from ESP32!” with T-Call ESP32 SIM800L am I’m not well succeed . Running the AtDebug available in library it gives me the follow message:
14:54:38.388 -> ***********************************************************
14:54:38.388 -> Module does not respond!
14:54:38.388 -> Check your Serial wiring
14:54:38.388 -> Check the module is correctly powered and turned on
14:54:38.388 -> ***********************************************************
Do you have any idea of what’s wrong ?
Grato,

Hi.
Are you sure you have a T-Call ESP32 Sim800L? If you have a slightly different module the pinout might be different and you may need to initialize the module using different pins.
Regards,
Sara

Hi Sara,
Acrescentei ao codigo :
int RegSta = modem.getRegistrationStatus();
SerialMon.println(RegSta);
E o resultado que obtenho é :

11:27:47.312 ->

Hi again.
I just used the code on the blog post. Everything worked as expected.
If you have the exact same board, no additional changes should be needed.
I don’t know what might be wrong.

Sara

Hi,
I think im not using exactly the same board, you are using v1.3 and im using v1.4

Do you have the pinout for your board?
Check your board’s pinout and see if you need to change any of the pin assignments in the code.

Sara
