Unable to modify receive window duration

[HunterZhang888]

I want to increase the receive window duration.The OnRxWindow1TimerEvent and OnRxWindow2TimerEvent function will call the RadioRx( uint32_t timeout ) function to start the RX window and set timeout time. The two parameters,timeout and RxTimeout, passed to this function, all have large numerical values（timeout=3000 and RxTimeout=0xffff）.But the actual measured receive window duration is approximately 260ms.But no matter how I modify the RxTimeout parameter in the RadioRx function, the IRQ_RX_TX_TIMEOUT interrupt of sx1262 is always generated within 260ms after receiving is enabled.
