Cannot download a new firmware

Hi there,

I’m working on Sierra Wireless GL6100, RS232.

I developed a custom firmware that switch the UART1 to data mode with baud rate 9600.

Throw the COM, I can switch back to AT command mode but when I try to download a new firmware I get this error from developer studio:

Error: Ati3Callback

Is this problem related to the UART baud rete?

I try to set the baud rate (throw AT command) at 115200 but nothing has changed.

Any suggestion?

Thanks in advance!

firmware or application?

normally default baud rate for sierra firmware is 115200. so in your firmware\application you have changed the baud rate to 9600? then what baud rate module was working?

Now what is the status of the modem? it’s in 9600 baud rate? are you able to communicate with the modem?

I solved the issue stopping the application at boot with the AT command, then I change the baud rate to 115200 with AT command and finally I save the this changes with AT command.

That’s works!

Thank fedex, I did as your tutorial.
