This is due to a bug in the BREW version 1.0.1 SDK - connect callback is not invoked under the following circumstances:

• Service is lost while connect is being attempted
• SERVER does not respond

As a workaround, you should implement a timer in association with the callback. If the connect callback does not occur in 30 seconds, you should timeout the connection.

For example:

// initialize pMe->connectCBInvoked = FALSE;
// Set timer for 30 seconds before invoking ISOCKET_Connect()
ISHELL_SetTimer(pMe->a.m_pIShell, 30000, ConnectTimeout_CB, (void *)pMe);
ISOCKET_Connect(pMe->m_pISocket, nodeINAddr, AEE_htons(USAGE_TEST_PORT),
SampleApp_ConnectCB, pMe);
// Set flag indicating connect CB was called
void SampleApp_ConnectCB(void *cxt, int err) {
SampleApp *pMe = (SampleApp*)cxt;
// Set flag indicating connect CB was called
pMe->connectCbInvoked = TRUE;
if (err) {
DisplayOutput((IApplet*)pMe, 3, "Connect failed!");
return;
}
DisplayOutput((IApplet*)pMe, 3, "Connected!");
}
// When timer expires, check if connect CB was invoked
static void ConnectTimeout_CB(void* cxt) {
SampleApp *pMe = (SampleApp *)cxt;
if(pMe->connectCbInvoked == FALSE) {
// Callback was not invoked within 30seconds - cancel connect callback
ISOCKET_Cancel(pMe->m_pISocket, 0, 0);
DisplayOutput((IApplet*) pMe, 3, "Connection TIMED out");
}
else {
// Callback invoked. Set flag to default value FALSE
pMe->connectCbInvoked = FALSE;
}
}

NOTE: Multiple TCP SOCKETS are not supported on the Kyocera 3035. It allows one TCP socket and one UDP socket at a given time.
