GE864-QUAD V2 F/W which does not have #CFF command

6 thoughts on “GE864-QUAD V2 F/W which does not have #CFF command

  1. I have the V2 (F/W 10.00.025)  but the #CFF unsolicited reply back from module with o2 sim cause me big issues with existing controlling software.

    I used to use the QUAD with F/W 7.03.102 but this won’t download to V2 with X fp programmer.


    Is there a F/W release for the QUAD V2 which doesn’t have the #CFF?








    1. The latest firmware for GE864-QUAD V2 is 10.00.026; the latest that hasn’t AT#CFF is 10.00.024, I sent you a download link.

      1. The 025 version seems to  cause an error reporting back  when activating socket on GPRS (SKTOP) the 024 works fine.


        I dont want to program each V025 module with Xtp (which takes over 8 mins!) down to V024  if I can avoid it.

        On the V025 if  I set AT#CFF=0 after boot up and use AT&W and AT&P this does clear the #CFF when rebooting but SKTOP error still occurs.   


        Do you have a way of using V025?







  2. I have compiled a listing of setup attached, using V025 code. NOTE: This is what is seen coming from Telit only.


    I have found that even though #CFF does not report on power up,  the module still fails to connect with O2 SIM, but when swapped for T mobile it works. changing back to O2 then works all the time after that!


    Using older versions of the Telit F/W works all of the time.




    1. Hi Barry,


      #CFF is disabled by default  as far as I can remember so, if it wasn’t previously set to 1 by your application it shouldn’t be an issue.

      In any case if the real problem is the AT#SKTOP failing, you should change something in your code.


      First of all you are mixing AT#GPRS and AT#SKTOP commands. 

      – AT#SKTOP command has to be used in combination with AT#SKTSET where remote host is configured. If the #SKTSET is not configured, before AT#SKTOP, the socket cannot be open. I don’t see AT#SKTSET when you turn on the module, the first time with O2.

      AT#SKTOP performs PDP context activation, and socket open. When the socket is closed also the PDP context is deacitivated. This is the old IP Easy style.


      – AT#GPRS=1 activates the PDP context, and has to be used in combination with AT#SKTD that open the socket. When socket is closed, the PDP context is maintained active (same IP address for further connections)


      Anyway both 7.03.102 and versions support the new set of commands AT#SGACT and AT#SD that we suggest to use (see IP Easy User Guide).


      In any case, the combination AT#GPRS=1 and AT#SKTOP is wrong.
