Hi! I’m using a fastrack XTEND EDGE(FXT009) and from time to time I get some garbage in terminals. Something like that: // Using Hyperterminal è +CFUN: 1 ®ªè OK èª +WOPEN: 0 ªè OK ` // Using putty +CFUN: 1 ®ªè OK èª +WOPEN: 0 ªè OK ` @N§Êå @N\*0 @NòH® Do you wonder why is this happenning? Firmware is 7.44 version, and OS is 6.34(package 2.34). Is it possible that the modem is broken? Thank you! ---

Your modem could be in developer mode. Switch to production mode using AT+WDM=0 ---

You’re right, but indeed I must debug some applications so I guess I need to have it in development mode, am I right? ---

You should use Developer Studio for debugging, as it can decode the AT command and development information correctly. Development mode is used by Developer Studio to get traces from the device for debug (please refer to Developer Studio documentation for more details). ---

I went to the terminal because M2M Studio is failing with a known bug where you cannot get status at first try(in my case, neither at first, nor at any try) and you cannot use almost every functionality of target status, so it’s enough for me to see the output of my apps on the terminal. ---

Then disable developer mode as stated above if you don’t need it! ---

doesn’t it avoid terminal output? ---

No, only additions trace and debug information that Developer Studio uses. Your normal serial communications will still come through in production mode, and you can still send and receive AT commands. ---

Ok thanks! But it’s still normal that M2M studio does not shown anything in status page even though I use production mode?
