Please refer to the website for more information about HL/RC Module Evaluation Kit Shield Shield setup. .. _HL/RC Module Evaluation Kit Shield guide website:
Before trying to set up a wired connection between the board and a host MCU, it's a good idea to first go through this list of basic AT commands over a USB COM port on a PC. For reference, you can find all the AT commands for the HL78xx modules in the Source.
Requirements
This shield can be used with any boards which provides a configuration for
header connectors and defines node aliases for UART, SPI and USB interfaces (see
:ref:shields for more details).
Programming
Set --shield swir_hl78xx_ev_kit when you invoke west build. For
example:
.. zephyr-app-commands:: :zephyr-app: samples/drivers/modem/hello_hl78xx :board: st/nucleo_u575zi_q :shield: swir_hl78xx_ev_kit :goals: build
Documentation
For full details, see :ref:hl78xx_auto_baudrate.
