Hi All, Have anyone solved the problem when pjsip for symbian reconnected after WIFI(network) is lost ? I coded my app by imitating symbian_ua. PJSIP's initialization was ok,Register was ok. If I called then talked with someone by pjsip,the pjsip crashed when WIFI couldn't be used(WIFI was lost)suddenly. After the connection was lost , my app called pj_symbianos_set_connection_status(PJ_FALSE) and pjsua_destroy().The app crashed when called pjsua_destroy(). If I didn't call then talk to someone,everything was ok when WIFI was lost suddenly. PJSIP could call pj_symbianos_set_connection_status(PJ_FALSE) and pjsua_destroy() correctly,It could unregister acount,destroy pool,shutdown media transports and so on.My app could reconnect WIFI and call symbian_ua_init() again ,It could register correctly again.. I have read the documentation(http://trac.pjsip.org/repos/wiki/Symbian_AP_Reconnection). I did implement the connection monitors like "connmon"" into my application.The codes below: //Begin Code class CConnStateTimer: public CActive{ public: static CConnStateTimer* NewL() { CConnStateTimer *self = new (ELeave) CConnStateTimer(); CleanupStack::PushL(self); self->ConstructL(); CleanupStack::Pop(self); return self; } public: void Start() { Cancel(); // Cancel any request, if outstanding iStatus = KRequestPending; myWebClient->iConnection.ProgressNotification(nifProgress,iStatus); SetActive(); } void Stop() { Cancel(); } ~CConnStateTimer() { Stop(); } private: CConnStateTimer(): CActive(EPriorityHigh) { CActiveScheduler::Add(this); } void ConstructL() { } void DoCancel() { myWebClient->iConnection.CancelProgressNotification(); } void RunL() { if(nifProgress().iStage==KConnectionClosed || nifProgress().iStage==KLinkLayerClosed)//Connection is lost { if( isSIPInitSuccess) { pj_symbianos_set_connection_status(PJ_FALSE);//Set Connection Status PJ_FALSE, PJSIP was still ok... pjsua_destroy();//pjsip destroy,.Problem happened when called it. PJSIP crashed... isSIPInitSuccess=EFalse; iReInitState=EFaile; isSipHasInit=EFalse; if(myAppUi->IsCalling()) { myAppUi->SetCallState(EFalse); if(!isWelcomeView) { switch( myDocument->GetActiveViewId()) { case 0: { myContactsView->SetCBACall(); } break; case 1: { myTempInputView->SetCBACall(); } break; default: break; } } } // Destroy pjsua myWebClient->SetConnectionOpen(EFalse); } TBuf8<32> st_failed8; st_failed8.Append(_L8("??????????")); TBuf16<32> st_failed16; myAppUi->ChineseConvertToUnicode(st_failed16,st_failed8); myAppUi->ShowMessageByMsgBar(isWelcomeView,st_failed16); isRegisterSuccess=EFalse; Stop(); return; } Start(); } private: TNifProgressBuf nifProgress; }; //End code I debuged the pjsip when call pjsua_destroy(), The debug information below: 1 .
