MSP432P401R: MSP432P401R

Part Number: MSP432P401R
Other Parts Discussed in Thread: CC2564


I am using a MSP432P401R and a CC2564 to form a bidirectional SPP <-> UART bridge. For the HCI UART I am using the provided HAL (baud rate 2000000) and for the Host UART I am running at 921600 and have implemented hardware flow control and DMA on the receive path.

I developed a stress test that sends messages in both directions. During the running off my stress test, I am getting very occasional (less than once per hour) CRC errors in the SPP->UART direction. What could be causing this issue? Is it possible the issue is with the CC2564?
