DSPS dropping bytes when extended sleep is enabled

Hi All,

I am using the SDK 5 version of DSPS and have a problem of it dropping bytes when extended sleep is enabled. I am transfering 1024 bytes to the da14580 from another micro via uart with hardware flow control enabled. It works great if default sleep mode is set to off but when extended sleep is enabled I start losing bytes in the transfer. Usually it's only 1 or 2, sometimes it's 10 - 15. Does anyone have any thoughts on what the problem could be? Thanks.

Device:

DA14580

Hi Dave,

Make sure that the hw flow control signals are properly connected and also what you can additionally try is to lower the baud rate of the project and check if you are still loosing data during transfer.
