First of all I turned the GPS off. I also have 30s send interval. I am not having problems with the device sending data. When I power both on and reset the sensor, I see data in both the packet manager and the application Live Device Data fields. I have a problem if the gateway is power cycled.
Yes, I understand it does not save data from before. I am saying that there are no ACK messages sent from the gateway after the gateway power cycles. This is a problem because now the sensor does not know the gateway is getting the data so it retries multiple times and uses more power.
The DevEui, AppEui, and AppKey are the same in the device and the gateway. Like I said above, I see data in the Application Live Data before the gateway power cycles.
Why would the gateway stop sending ACK messages after it power cylcles? That is the big question that I want an answer to.
