I am working with EC25-EUX and FC20-Q93 modules and I designed my own PCB to work with trying to share internet over wifi. I have successfully achieved a 12 Mbps internet connection via USB.
Usb connection works fine
When i check wifi connection i get error message like this.
I made the design by making use of the hardware design documents, I think that the pins are connected properly. I tried 2 different PCBs to test, I get this error in both wifi connections. When I measure the SDIO pins with a multimeter, approximately the same value is measured between all of them and I think the paths and pads are connected.
I look forward to your help in this topic.
Thank you very much.
