Hi i just tryed command with terminal set uart b 12500

and now my wifly doesnt respond to any skeches and not connecting to any networks i cant even sent commands thru terminal anymore

Please someone help me whats happened???

Do you mean 115200?

According to the WiFly user guide:

set uart baud set the UART baud rate. Valid settings are {2400, 4800, 9600,

19200, 38400, 57600, 115200, 230400, 460800, 921600}.

and

set uart raw sets a RAW UART value. Used to set non-standard rates. The lowest

possible baud rate is 2400.

Did you “save” the configuration after you set the baud rate? If not, then turning the device off and on again should reset to the standard baud rate.

I think you have two options if you saved the configuration:

  • - Try changing the baud rate of the SPI UART.

  • - Use the hardware reset feature described in section 16.1 of the WiFly user manual:

    • From hardware, setting PIO9 high on power up arms the factory reset functional and toggling PIO9

    five (5) times there after causes the configuration setting to restored to the factory reset.

    PIO9 is sampled at about 1 Hz, so if using a CPU to generate the signal, make sure that PIO9

    transitions (H to L or L to H ) are at least 1 second long.

    sorry yes i ment 115200 and yes i did save it and thing is i am uit new at all microcontroler obsesion so i have no idea how to change Spi Uart baud rate or how to generate that 5 times 1H this one i this is somthink like blink Led with 1sec delay but i dont know shal i connect arduinos ground and say pin 3 to wifly POI9 and then launch arduino skech with 5 times blink?

    P.S. i am afraid to do somthing wrong and fry my wifly module.

    Thanks for updating me with that information.

    I hadn't done either of those things before either which is why I just quoted the user manual. :)

    I’ve since looked into doing a hardware factory reset and from looking at the schematic it seems it might be possible with the shield but I’ve contacted the engineer who designed the board to confirm this.

    I then looked into changing the SPI UART baud rate and have implemented this functionality but unfortunately (as first discovered by another forum member) it appears that communication at speeds other than 9600 and 38400 may not be possible which means we can’t change the SPI UART to connect at 115200. I’ve passed that information on to the engineer too and will update you when I find out more.

    Also, for future reference there is a WiFLy command that will change the baud rate immediately but only temporarily:

    set uart instant <rate>

    P.S. i am afraid to do somthing wrong and fry my wifly module.

    I am familiar with that concern. :)

    Thanks for your patience.

    unfotianatly i jsut fried my shield tryed to add power to pio9 and touch sense pin with 3.3v ant it gone dead.

    Will order new one next week

    And thank you for your help
