7.6.8. CMD_GPIO_REMOTE_READ_REQ
This command reads the free GPIOs of the remote device. This command can be only run
successfully if the respective pins of the remote device have been configured as output or input
pins before.

This response is followed by a
CMD_TXCOMPLETE_RSP
to indicate the completion of the packet
transmission. If the packet was correctly received by the remote module, it responds with a
confirmation message containing the GPIO values. The response from the remote module is
