Serial master interfaces

Serial Master-Interface #H

Command group to use the 3 serial interfaces of the module and use them as master. For example to connect additional peripherals like temperature sensor.

ATTENTION: An update of the project or the firmware is no longer possible via the master interface. In this case, use the USB interface or a free slave interface.
