P-NUCLEO-LRWAN2 Debug Problem


Hello, I bought this development kit to learn LoRaWan technology and improve myself.


STM32 Nucleo pack LoRa™ HF band sensor and gateway.

I made the connections of the product as written in the User's Manuals and saw that the product was working. I received the sensor data in the LorIOT portal without any problems. In other words, both the Gateway and the sensor board are working without any problems.

Then I wanted to make changes on Code and I downloaded I-CUBE-LRWAN software expansion for STM32Cube (UM2073) from ST.Com and opened it in STM32 Cube IDE. I compiled the code without any problems and uploaded it to my I-NUCLEO-LRWAN1 board without any problems.

When I start the debug process, it gives this error.

"Target is not responding, retrying..."

"Error! Failed to read target status

Debugger connection lost.

Shutting down..."

I also get this error message when I stop the Debug process after this error.


Where am I going wrong?

Sounds like the Target is going to sleep, so the debug connection is lost.
