title: "Target is not responding, retrying..." ST LoRaWAN AT_Master/End_Node programms not working on NUCLEO-L073RZ
body: <p>I've read all topics regarding this error on the forum but nothing helped.
  The borad connected to Arduino connector is USI® WM-SG-SM-42.
  Projects build succesfully and connect with the board through ST-Link v3. This is the output I get when debugger and low power work is not enabled(set to 0):</p>

  <p>When debugger is enabled console output is the same, without the &quot;Target is not responding, retrying...&quot; part. Program just falls into HAL_PWR_EnterSLEEPMode() or HAL_PWR_EnterSTOPMode() fuction depending on low_power mode configuration. It stays there forever, which isn't an expected behaviour.
  Here is a debugg configuration:
