I would like to ask you if you know of any ESP32 and GSM module that is not a LILYGO TT-CALL SIM800L?
I am using the LILYGO module and it connects whenever it wants without changing the code or location, there are days it works perfectly and others nothing.
Thanks for your help and greetings
Probably not a hardware issue. I’d guess it’s a coding issue or an issue with your ISP.
My money is on coding.
You can add a GSM module to any board if you wish.
You can try the LILYGO T-SIM7000G ESP32. This development board supports 4G cellular networks and comes with a battery holder, a battery charging circuit, a microSD card slot that can be useful for data logging projects or to save configuration settings, and more.
How does it work with Blynk, is it stable?
Because the LILYGO SIM800L connects when it wants and for as long as it wants.
Thank you all very much for your advice.
I’ve used the Lilygo T-Call with Blynk and it’s proven extremely reliable.
As I said earlier…
I’m reviewing the code, following your suggestion. The previously mentioned, sometimes it works and other times it doesn’t, with the same code.
Do you have any example code link, only with the connection to Blynk.Cloud to serve as a reference or as a starting point?
I’d suggest that you post the code that you’ve been using and having problems with.
Thanks, I’ll compare it with my code.
Thanks, I didn’t know her.
