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.

Hi,

This is possibly due to the power...

I believe you might be powering ON through your USB port which may not give sufficient current to power ON the module,

Use the external power ...!

It should solve your issue...
