LIN master stops transmission when no respose

Dear, 

 

I am trying use KEAZN64 as LIN master node and I used FSL_LIN_2.x_STACK_Package_4.5.9 to generate LIN code.

The communication was correct when slave node responded rx frame. But if a rx frame sent by master has no response, the master node will stop transmission and no more frame header will be sent ( Although the frame is scheduled in correct time as break field can be sent ).

 

I tried three ways out to result in the problem:

1. Disconnect LIN bus of slave node.

2. Slave node stop LIN function but LIN bus connect.

3. Master send a frame but there is no related slave node response.( In this case, the first frames that have responses were sent correctly) 

 

I haven't found any related explain or how to set master node in LIN spec and LIN stack user manual. 

 

Thanks
