I am trying to get a list of the operators of my location. But the received data is truncated. Please tell me why this is happening.

Choosing a different UART port solved the problem. I knew about the error in the diagram with the connection of pins, so I did it right right away. But I can't connect to the network, although there are many 2g networks in my area and the SIM card supports this mode. The module finds the networks, b...

Hmmmmmm..... Maybe you right . I will try this. Thanks!

I'm trying to connect the stm32f411 board and the SIM800L gsm module. I have been suffering for several days. Rummaged through a bunch of manuals. There is an assumption that the board is interacting with the module, but errors are constantly appearing. Now in more detail .... I connected the boards...
