Hello @akash-lawande ,

Sorry for our delay reply!

Not sure if the issue has been resolved. 

I checked your connections of SDIO interface, it is no problem.

For communications between WiFi and MCU, please pay attention to IO Level on both sides. by default, on CPU side, SDIO IO Level is 3.3V. if you need 1.8V,  a jumper should be used on J55.
