Hello,
I'm trying to send messages from the cloud (AWS-IoT ) to the device, so I modified the device so that it subscribes to a new topic and when I send messages from could, it seems that the device doesn't listen frequently to the cloud. sometimes it receives a message, sometimes not. and when I sent multi messages very fast, the device receive all messages after a random delay.
I tried to check the code if there is any configuration I can use to force the device to listen to Cloud always. but without luck. This behavior is in Active and Passive mode as well.
My question is: How can the device receive messages instantly from the cloud without delay.
Thanks in advance.
