Hi ST,

 

Recently I try to enable AP or station mode on SPWF04SA wifi module,
I connect it with my PC via UART and I can see some feedback on terminal on my PC.

The question is, even though I can command SPWF04SA with its own AT command,
it always shows "+WIND:5:WiFi Hardware Failure:5", and I cannot see what's wrong with my board.

I followed this site to command SPWF04SA,

Please help me.
