SetRangingRole uising uart SX1280 [Urgent]

Good afternoon,

I have configured all of the steps for the SX1280 Ranging but i came acroos a problem with set ranging role. There is no example in the datasheet of how to use SetRangingRole using uart, which the interface i am using. Can someone explain to me what packets i must send to the tranceiver in order to configure it as master using uart? Thanks in advance
