Hi all, I am using Q24+(657e) as my wireless module. when i try to create a server using “wip\_TCPServerCreate(SERVER\_PORT,evHandler,NULL)()”, where SERVER\_PORT = 8888 m getting the message in trace “ERRLOG ch\_tcp\_server.c:104: Assertion Failure:” what does it mean. One the above TRACE starts coming I am not able to connect to the created server from client.Please help me in solving it. The trace is as follows Trace CUS4 1 Got missed call Trace CUS4 1 [GPRS]: open: -\> DISCONNECTED Trace CUS4 27 Call subs 00238201 : 0 Trace CUS4 31 Gprs subs 0022B845 : 0 Trace CUS4 30 [ADL port] IsAvailable(80) : 1 Trace CUS4 31 Gprs setup 1 : 0 Trace CUS4 1 [GPRS]: start: -\> CONNECTING Trace CUS4 21 Get Mem 01079328 Trace CUS4 1 [GPRS]: GPRS EVENT SETUP OK (cid=1): GPRS activate Trace CUS4 30 [ADL port] IsAvailable(80) : 1 Trace CUS4 21 Get Mem 01079418 Trace CUS4 21 Get Mem 01079538 Trace CUS4 21 Get Mem 01079508 Trace CUS4 1 [GPRS]: GPRS EVENT ACTIVATE OK (cid=1): FCM open Trace CUS4 25 Is Available 60 : 1 Trace CUS4 25 FCM subs 96 : 11 Trace CUS4 1 [GPRS]: FCM subscribe: 11 Trace CUS4 1 [GPRS]: FCM EVENT FLOW OPENNED: -\> CONNECTED Trace CUS4 21 Get Mem 01079550 Trace CUS4 1 ERRLOG ch\_tcp\_server.c:104: Assertion Failure: Trace CUS4 1 \> FALSE Trace CUS4 1 Trace CUS4 1 Trace CUS4 2 117.97.104.58 Trace CUS4 26 SMS send : 0 Thanks in advance, Chethu ---

An Assertion is a standard programming technique for catching errors in programs: [en.wikipedia.org/wiki/Assertion\_(computing](http://en.wikipedia.org/wiki/Assertion_(computing)) This one looks like some internal Wavecom message - you will need to contact your distributor or FAE about it. ---

Hii As you must be knowing , If an assertion evaluates to false at run-time, an “assertion failure” results, which typically causes execution to abort. > [@](#): > > This one looks like some internal Wavecom message - you will need to contact your distributor or FAE about it. Exactly…!!! This message would be received once the condition evaluates to false at run time. Since , the code is running first time and the error is received second time , i feel the opening and closing of the server socket is not done correctly. The problem seems to be with the Code itself. Hope it is of some help to you… 🙂 Regards, Paruthiv ---

S ur absolutely correct I was not closing the server channel at all. because of which i used to get this after 7 connection and disconnection.Thnx for the solution…
