How is your device connected? Are you able to ping the platform from the device?

This might indicate a poor connection. That being the case, consider increasing the timeout.

Hi Nisha Bhagtani​,

I had the same issue when I directly invokeService or Create Things after Client is started without waiting some time.

You could also try if it works for you.

Try to add code:

//add this code rightly after client.start();
//you could consider to increase/decrease the waiting time(30000 ms in my example) per your test result
if (client.waitForConnection(30000)) {
// Create things, invoke services, etc. here
//......
}

Thanks,

Br,

Anna
