CC2642R-Q1: Change the TX power

Part Number: CC2642R-Q1

I wanted to change the transmitting power of the device while the program was running. I called HCI_EXT_SetTxPowerCmd interface and found that the actual power did not change in the app side. In the LAUNCHXL-CC2640R2: TxPower not changing when HCI_EXT_SetTxPowerCmd() is called - Bluetooth forum - Bluetooth®︎ - TI E2E support forums, I didn't find anything that worked. So what should I do?
