duplication of state messages

[biancoblu79]

Hello,

I am getting duplicated device "state" messages and I believe that's because of of sending them to both the state and the telemetry topics upon connection ...

void CloudIoTCoreMqtt::onConnect() {
if (logConnect) {
publishState("connected");
publishTelemetry("/events", device->getDeviceId() + String("-connected"));
}
}

is there a specific reason for sending state messages to the telemetry topic? I commented out the publishTelemetry line for my use case.. but was wondering if there was a particular reason for having that line of code.

thanks!

Hi Marco thanks for the feedback,
there isn't a specific reason for sending state message and telemetry message other then just having the ability to send the two messages, but the code above shouldn't send a duplicated state message unless you're calling onConnect() multiple times.

Hi galz10, thanks for the reply. I actually need to send these messages and to 2 different subfolders in Cloud IoT Core. I was just wondering why the state message was sent, together with device data, to the default telemetry folder. I just commented a line of code out and I am sending the state message separately from the telemetry data.. thanks!
