Hello @ethan_dang1 

Thanks for sharing and contacting us and interested in the NXP products.
So, I'd like to know what if you extended the POLLING period, the same phenomenon?

Hello @ethan_dang1 

If you extend polling without any more crashes, then there is probably a problem with the matching timeout between the test application what you're used and PN7150. It is difficult to debug and match this timeout because the application is not NXP and its specific implementation is not clear. The only solution is to try to adjust the polling interval.
