I am a professor teaching a college course one IoT systems and we use the Arduino Cloud in my course. My students are looking at an application where a device will routinely disconnect from the cloud service due to leaving the connection area. I am uncertain how to handle this type of data. I see two scenarios, 1) the sensor leaves the coverage area and continues to collect data creating a series of data that needs to be sent to the cloud when it reenters the service area, 2) the sensor starts outside the service area so at the time of the first connection to the cloud there is already a timeseries of data that needs to be pushed to the cloud. I've dealt with this in other applications through a data buffer, but I don't see this type of functionality in the IoT Cloud. Is there a way to do this that I am not seeing?
Hello,
Arrays are not supported by the IoT Cloud of Arduino
https://docs.arduino.cc/arduino-cloud/cloud-interface/variables/
What's the point of sending those data to IoT Cloud? Making a chart or just saving the data?
When the sensor isn't disconnected, how the things work?
Just save the data onto an SD card and when you regain the cloud access send that data first before any new data using the same sending mechanism.
