Wio E5 mini stm32 f/w using SUBGHZ_PHY middleware trouble issue

Hello. I am trying make a p2p project using 2 wio e5 mini module.

This is what i am encountering now.

  1. first module successfully transmitted 11byte packet via LoRa
  2. second module successfully receiced 11byte from first module
  3. second module successfully transmitted 10byte response packet via LoRa to first module
  4. first module cannot received 10byte response module.

i have checked usart debugging line.

First module succesfully transmitted(OnTxDone callback function is called), But Cannot received response from Second module…

Second module successfully received and successfully transmitting

I found that when I set LoRa mode to RX and check currentstate in RadioRxReady function, LoRa modem mode is successfully setted to Rx. However, as soon as system goes into RADIO_RX_WAIT state in next loop, it goes to Standby mode. I cannot understand why the RxTimeout is called. It is about clock setting?? Could help me with this situation?

For Your Reference I dont use utility provided by st. No Sequncer, NO UTIL_TIMER.
