Hi,

 

 we are working in ATSAMD51J19A controller. Our USART RX packet length is 8 bytes. Controller receive this 8 bytes  every 500ms. Randomly, we are facing  two or three byte missing in USART receiver side.

Our baud rate setting : 38400

 

Actual data  transmitted to controller:  5A 01 07 00 00 05 32 EF

Data Received in controller               : 5A 01 05 32 EF 5A 01 07

 

kindly give suggestion to solve this.

 

Thanks & Regards,

Poovai.L

That's not easy when we know nothing about how the reception is implemented (and nothing about what else is going on in your application).
