Directly control Up2Stream Pro V3 from MCU?

I would like to directly control the Up2Stream Pro V3 from a microcontroller and have been thinking of using the UART (TX, RX pins) to do this.

However, I’ve seen from the UART API docs that I cannot, for instance, set an URL to play music from. However, this function is available using the HTTP API.

I could connect a WiFI module to the microcontroller and connect to the Up2Stream Pro using HTTP, but this seems a rather convoluted way of doing it.

Is there a way to use the UART connection to get functionality similar to what is offered by the HTTP API?

Thanks,
Andrew

technically possible, but currently did not have such API implemented.
