Hi Everyone, I’m about to my wits end trying to get my Wifly into command mode, I’m not sure if it’s a software problem, or if its hardware. I’ve tried using Sparkfun’s WiFly Transparent Terminal Sketch [http://www.sparkfun.com/commerce/images … rminal.zip](http://www.sparkfun.com/commerce/images/WiFly_Tutorial_Files/WiFly_Terminal.zip), and the new Arduino Library, in both cases the WiFly just hangs after I get the Bridge initialized successfully message. Below is all that the WiFly every prints to the terminal window.

```auto
WiFly Shield Terminal Routine
Bridge initialized successfully!
WiFly Ver 2.18, 02-02-2010
MAC Addr=00:06:66:00:3a:cf
A

```

I assume that it’s stuck in a loop somewhere since I can’t even input the “$$$”, and I’ve never seen it display CMD. I’ve tried different terminal emulators, both on a Mac and PC, I’ve tried different arduino’s with all the possible sketches that anyone has every posted about, but I still can’t get this to work! Am I missing something? or maybe I just have faulty hardware? Any advice would be greatly appreciated.

Thanks for the help!

Try one more thing in void autoconect somwere add factory RESET

like so

[http://www.sparkfun.com/commerce/images … onnect.zip](http://www.sparkfun.com/commerce/images/WiFly_Tutorial_Files/WiFly_Auto_Connect.zip) download this skech first,

then begining of this

```auto
char autoconnect(void)
{
  // Exit command mode if we haven't already
  SPI_Uart_println("");  
  SPI_Uart_println("exit");
  delay(500);

  // Enter command mode 
  SPI_Uart_print("$$");
  delay(500);

```

change to

```auto
char autoconnect(void)
{
  // Exit command mode if we haven't already
  SPI_Uart_println("");  
  SPI_Uart_println("exit");
  delay(500);

  // Enter command mode 
  SPI_Uart_print("$$");
  delay(500);
  // factory reset 
  SPI_Uart_print("factory RESET");
  delay(500);
  // save
  SPI_Uart_print("save");
  delay(500);

```

let it run for a few second then try transparent terminal([http://www.sparkfun.com/commerce/images … rminal.zip](http://www.sparkfun.com/commerce/images/WiFly_Tutorial_Files/WiFly_Terminal.zip)) skech or unmodiefied auto connet one hope will help

it help me when i coudnt change ports needed factory reset but terminal wasnt sending any commands after this one all working fine so far

Hi

I’m just learning how to use the WiFly module. I designed a board with PIC to control it. I managed to connect to command line using hyper terminal. I noticed I could only connect to command line $$$ if GPIO-9 is at hi level 3.3v(ADHOC MODE) Then I managed to set commands using PC. May be this is the solution to your problem.

I’m still having trouble connecting it to my wireless router, I will report here when I do further reading.

Hello,

Are the RTS/CTS reversed in RN-121 (wifFly module) compared to the standard active high logic?

Have you gotten an answer???

I have an RN-121 also. I used the set baud flow 1 to set it, but I still can’t get anywhere either.

Found that if you set the comms parameters in the SC16IS750, then make sure that the crystal is the right speed… all of a sudden everything started working for me. It’s still a little slow and buggy, but I’m heading into the right direction…

I’m having the same problem! It never enters the CMD mode… Could you please share your solution?
