I have a SPWF01SA wifi module initially it is all good I communicate with him through a terminal. I do a reset control module (AT + CFUN = 1) then it always enters a reset mode and does not accept any command. How can we get out of this infinite loop reset.

I think i did not get your question.

Take a look at boot pin. Is it high (2V5)? It means that inner STM32 is in boot mode, and, so, application into SPWF does not start...

Hi,

Thank you for your reply, I have another question :

is that there is a command to cancel for a period, asynchronous outputs sent by the module (''+ WIND: 21: WLAN Scanning'' or ''+ WIND: 35: Complete Scan''). I test this variable but no results ''wifi_print_scan_results'' .

Hi,

unfortunatelly you have a very very old firmware. that variable does not exist since a long time...

When the module is not connected, you cannot stop scan (unlee you use the ''at+s.wifi=0'' command), but... since FW Release 3.x on, there are 3 variables called wind_off_low/medium/high. Default values are 0x00000000s. It's a bitmask.

- wind_off_low manages wind:0 to wind:31

- wind_off_medium manages wind:32 to wind:63

- wind_off_high manages wind:64 to wind:94 (wind_off_high[95] is reserved)

Example:

- ''at+s.scfg=wind_off_low,0x00200000'' hides wind:21

- ''at+s.scfg=wind_off_medium,0x00000008'' hides wind:35

- ''at+s.scfg=wind_off_high,0xFFFFFFFF'' hides wind:64 to wind:94

I don't know if you want to stop scan, or only hide WINDs messages...
