SIM800H status problem

MonlyDwain report abuse

Hi everyone!

I am using SIM800H module with a connection to GSM network. The problem appears when I start interfacing it - connection status is failed. Can you tell me what are the possible reasons? I am using AT commands through a USART connection from STM32f1 to access the module.

Hi MonlyDwain,

The reason of your problem might be non-compatibility of your devices? You should use another controller and you will see the difference.
