S32K344 Data cannot be received twice in CAN loop mode

[Neo1096]

I use s32k344, RTD 1.0.0 

I want to implement three arrays into three sending mailboxes at a timer interval of 1s, polling in the main function, handling in the interrupt. But how do I know if I didn't send or receive it in loop mode? At present, I can only receive the first set of three data, and the following two data cannot be received. Is there any flag that needs to be cleared?
#S32K344

Hi,

after successful receive you need to call Receive function again, to update internal driver structure and enable MB interrupt again, if used.
