switch from async mode ( WIND) to normal AT CMD in UART stream

Hi guys,

I'm using SPWF001 and wanted to write my parser since the host MCU is not STM32 (so I cant use the example).

Simple question: If the module is in the middle of +WIND:xx:yyy, and I send an AT Command, is the current string is cut or the module will finish the string and will respond to AT Command.

In other words, is this possible:

<cr><lf>+WIND:xx:yyy<cr><lf>OK<cr><lf>yyyyyyy<cr><lf>

or it will always be:

<cr><lf>+WIND:xx:yyyyyyyyyy<cr><lf>

THANKS YOU

Hi Mikael,

both hypotesis are wrong

WINDs are queued/delayed from 'a' of AT-command to 'CrLf' of resulting OK/ERROR. So, your parser will never receive an indication during command execution.

Hi Jery,

Maybe you can help me.

I'm checking if it is not better to port the ST Cube wifi library on my board instead of rewriting new parser.

Can you tell me what are the following timing:

1) Wifi_TIM_Handler

2) Systick_Isr

Thanks

Mikael

Timings are 10ms for the TIM_Handler and 1ms for the tick_Isr.

Thank you very much...

And the last question (I promise you )

Is the UART_RxComplete_Callback is called in interrupt context or not ?

Thanks
