How to set up wireless transmission via UART on MSP430?

I assembled the circuit with the MX-RM-5V receiver and FS1000A transmitter on the MSP-EXP430G2 debug board with the MSP430G2553 controller installed. I ran into the problem of writing a setup program, since I have never done anything like this. Where to start? Let's say I can initialize the UART interface (by examples)

Yes everything is correct.
initialize the uart port.
then put the byte in the transmit buffer and turn on the transceiver.
in the loop, look at the state of the transmission flag and after the end put the next byte in the buffer. and so on.
study the datasheet - texas describes everything qualitatively.
on the official page there is a collection of code samples, it has
sp430x20x3_ta_uart2400.c Timer_A, Ultra-Low Pwr UART 2400 Echo, 32kHz ACLK
