Simulating RF transmitter remote

[Deouss]

I successfully hacked my old garage remote which is RF 315Mhz and would like to transmit the signal using those cheap RF modules
It is actually very easy under Windows using SDR dongle
I am looking for idf library/code that will help with transmitting the sequence.
Can anyone help with best way of doing it? I really do not want to use Arduino - esp-idf is preferred.
Thanks!

It should be very similar to sending IR codes with RMT peripheral
