How can I reduce my Sleep current in STM32WLE5CCU6 microcontroller.

Hi All,

I have implemented a code using Arduno IDE. In that we are transmitting data at every 5 minutes. For that I am getting sleep current around 6uA. But When I am using STM32cubeIDE to generate same type of code I am getting sleep current around 5mA. 

How can I reduce this Sleep current. It is very much crucial for my project.

Please give your ideas.

It's not Sleep mode. Instead inventing your own names, use the names from documentation so that everyone can understand.

The particular issue can be solved by just disconnecting the device from the power once after flashing or by disabling the debug interface in code. It is described as an issue 3 in this article:

In case you are using Stop mode, a correct usage is described there:
