App server load

In the Practicing with AWS section below, we will run the Logtta CO2 demo. This app gets the advertisement that Logtta CO2 emits and logs the values of CO@ concentration.

We measured the load when running on the AWS EC2 T4g.micro environment. The results are as follows.

CPU credit usage[%]

network usage[MB/m]
(blue: IN, orange: OUT)

Load/communication volume

If obniz and the app server are connected and no processing is done, it will use 54 bytes per minute.

When the BLE scans specific advertisement packets, it will use about 300 bytes per minute.

⚠When using a Cellular line, it will use 768 bytes per minute even without any processing due to the limitation of the Cellular network.
