Performance between STM32H747-DISCO and Murata Type 1lv

[Danix2k]

Hi,

I'm evaluating the WIFI/BLE module 1LV by Murata with a STM32H747-Dicovery board and Murata adapter as reported in the PDF file in https://github.com/Infineon/stm32-connectivity/tree/master/Documentation

The connection works fine (wifi scan OK and connection OK) and now I'm trying to increase the communication performance; the first test, using LWIP stack as server on MCU and ipref client on windows/linux side gave me only 0.15-0.20MB/s (150kBps) that seems to me very VERY slow using SDIO interface (with 25MHz clock).

Do anybody have any clues to increase this bitrate?

What can I change from the test project (https://github.com/Infineon/stm32-connectivity/tree/master/Projects/STM32H747I-DISCO/Applications/wifi_scan) to increase WIFI performance?

Do you also think that LWIP stack is the correct "library" to have good performance (at least 2.5-3.0MB/s)

Thanks

I'd start here:

another point, commercial version TCP/IP stack may have better performance.

But you have to correctly use it. otherwise you will get similar throughput.

Ok. Thanks

Ha ha - very true!

One would expect a paid-for stack to have professional support to help you with this.

Be sure to test this out as part of any evaluation...

For everyone, who ever reads this topic... lwIP as a stack library has no problems of pulling speeds up to:

• 100 Mbps on STM32 MCU,
• 1 Gbps on NXP and Xilinx (page 22) devices,
• Several Gbps on Intel multicore workstation.
