so i every time when i try to conect my arduino h7 portenta vision shield lora. i use the exmple sketch:mjpeg_streamer_py.but when i connect to my iphone’s hotspot it say this error [CYW43] cyw43_kso_set(1): failed
sdio_transfer_cmd53: error=00000004 wr=1 len=64 dma=1 buf_idx=0 STA=00000000 SDMMC=00000000:00000c00 IDMA=00000001

Hi, it works as expected with my Arduino Portenta H7 and a Lora Vision Shield. Please update your firmware to the latest dev release. See Tools→Install Latest Dev Release.
I’m not sure, if you updated your firmware to the latest and it’s still not working then the hardware may be damaged. All I can say is that isn’t not a firmware bug. So, that just leaves a hardware issue.
