SPWF04Sx FW_1.1.0 SPI UDP socket throughput

Hi,

 

using newest fw and x-cube 3.1.0 in an UDP ping-pong application I can get no more than about 3kBytes/s.

I guess the reason is the "Socket Query for SPI interface may stall ..." "known limitation" mentioned in the Release Notes.

We need at least 10times that throughput: > 30kBytes/s.

Is it possible to achieve 30kBytes/s using UART?

Are there SPI fixes I could test?

Some github like beta repository?

 

tnx & best regards
