CC1352P: UART receive problem

Part Number: CC1352P

I have a proprietary UART communication protocol with another device and I have two cases of communication. 

  1.  I send a packet and then receive 
  2.  I wait for a packet from the device and then reply

In both cases, I do open UART before starting communication and close after finishing.

In the first case, communication works fine (Send and Receive)!

In the second case, a receive-callback function not running. I see at logic analyzer retransmit packets but no callback event lanched.

I use compiler version TI v18.12.4.LTS and SDK CC13x2 26x2 

Please suggest
