Lora ping pong debugging

[daniel833]

Hi, i have NUCLEO-L073RZ with shield I-NUCLEO-LRWAN1 SX1272.

I want to activate it with ping pong code and it’s stuck and I don’t understand why.

I can see that LD2 is blinking but PuTTY is empty, I also get this after running:

Hello ​@daniel833 ,

Try connecting under reset mode.

Check the debug pins assignment.

Note that the I-NUCLEO-LRWAN1 is an obsolete product. I recommend using the STM32WL products to establish a LoRaWAN connection.

Thank you for the advice! I verified that my interface is set to SWD and I am using 'Connect under reset' (see pictures attached). However, I am still getting the exact same 'Target is not responding' error. Are there any other hardware jumpers or sleep-mode issues I should check?
