The QSL includes a SimplePublish example for the STMicroelectronics NUCLEO-L053R8 development board. This is given as a project for the Eclipse/GCC based System Workbench for STM32, where STM32CubeMX has been used to generate the necessary Hardware Abstraction Layer (HAL) code.
The application behaves just like SimplePublish for the other platforms, and like the example for SAM C21; debug prints are re-targeted through a second serial port. A green LED on the Nucleo board is also toggled to indicate whether the mote has connected to a network or not.

Connect a USB cable from your computer to the USB-mini B port labeled CN1: This is the port at the top of the NUCLEO-L053R8 (visible on the right side of Figure 7), which connects the integrated ST-LINK/V2-1 debugger to your computer, and is used to power, program and debug the board.

You can (de)activate debug and log messages with the NDEBUG and NLOG defines in dn_debug.h (located in sm_qsl/). |

The output from the debug terminal has been shown to periodically stop working on Windows (although this does not affect execution of the application itself). Disconnecting and reconnecting the ST-LINK USB seem to make it work again (although this will of course reset both the Nucleo board and connected mote). If you still don't see any output when you should you can try the following:
