Why does in the BL072Z led LD5 keeps in green color?

Hi, in the datasheet of the BL072Z board says: (pag 17)

"LD5 = Green when communication "

But when I connect the board with the UART port to program and see the data in the terminal the LD5 is in red color and everything works ok, but then the LD5 sometimes turn on green and the node stop working, I had to reconnect it to restart the Tx, why?

thanks

Do you have most current firmware on the ST-LINK?

Does the COM port stop working, or the application you have running on the module?

Are you using Keil or IAR to do the debugging, or OpenOCD based like CubeIDE, etc?

Likely to depend on the ST-LINK firmware, drivers and how the operating system is interacting with it. The documentation may or may not track current behaviour. I'd focus on what's actually failing, and perhaps document the version of various system components so some specifics or commonality can be established..

Hi,

>Do you have most current firmware on the ST-LINK?

In device manager I choose update driver and says that the last driver is already installed

>Does the COM port stop working, or the application you have running on the module?

just the COM port

>Are you using Keil or IAR to do the debugging, or OpenOCD based like CubeIDE, etc?

I am using SW4STM32 eclipse but I don't have the debugger running, I just load the end_node code and open the COM port to see some messages
