Hello! I'm in the development phase of a project so I print the date time each time I reboot my device with the print command (time.localtime ()). And sometimes comes the result (2000, 1, 1, 0, 0, 4, 5, 1) which is the starting time date. But sometimes I get the correct correct date time. However I ...

Hello! Is it possible to use UART 1 or UART 2 on an ESP8266 NodeMCU? I want to use for communication between the ESP8266 and a SIM808. When I use phone = UART (2, 9600), it gives me an error that the port does not exist, when I use phone = UART (1, 9600) it replies that it is inaccessible. When I us...

Victory! I was able to solve it after some more research. I want to leave the solution here for someone who needs ... When working with SIM808 or another module that communicates with AT commands, everything is then by AT commands, even easier. ESP32 will not have access to the internet, but it will...

How do I do this?
As I already said, I can communicate with the SIM808, send SMS with AT commands, consult the coordinates of GNSS, everything works fine.
But how would I make an internet connection?

I added this snippet of code: gsm=UART(1,rx=16, tx=17, timeout=1000, baudrate=9600) ppp=network.PPP(gsm) ppp.active(True) when I execute these commands, the result is this: >>> print(ppp.active()) True >>> print(ppp.status()) None >>> print(ppp.isconnected()) False >>> print(ppp.ifconfig()) ('0.0.0....
