AMAZING!! It works, you made a nice work dude! I´m also trying it on TTGO ESP32-SIM800L but gets troubles on compilating. Any advice how to make it work on it?? That would be awesome! 😯😊

[@AhmadLogs]

you need to delete the sim800l software serial library. and use the built-in hardware serial port of esp32. to get some idea. you can grab the code from the description of the following video. kzbin.info/www/bejne/mqjFc2aPfMd1qLs.

[@nesuem]

​@@AhmadLogs Thank you for your answer, but that video works vias SMS, is it possible to manage it with GSM networks? I mean, using this library.

Sir I have a question when I configure blynk app to push button then sms command work push button or normal switch type.(continuous on or trigger only)

sir, what if im change the nodemcu to Wemos D1 mini? is it still work for blynk? beacuse im already tested but the sim800l dont get connected

Sir.. Im working on project with a closing deadline.. And really need your help.. How can I contact you more efficiently.. Im getting no memory sutable error, when im using Arduino uno ..

You are doing great work. Congratulations. Can you add to this work, receiving data from wireless sensors (dht22) and saving the data on an sdcard. For greenhouse management with wireless sensors (soil moisture soil temperature air humidity air temperature).

[@cheyo022]

Thanks it's a good project, i did it and it works although i have problems with the sim800L, it only works for 1 minute and then it disconnects from the blynk server, i tried 2 others sim 800l modules and the same thing happens, it works better for me with sms but it also loses the signal after a few minutes and it takes some time to connect again and it continous happening. Is there a way to change the sim800l for the AI THINKER A6 module?

[@AhmadLogs]

yes you can change it to A6 board.

@@rhonak I have tested the project for nodemcu with no issue. I think you have made some changes in the code and the code is larger then the flash memory of the nodemcu. so you need to reduce the code. if you have added lot a serial.print() functions in the code. then delete or comment some of them.
