Last week, I deployed a Boron LTE and an Argon and ran some tests using the “Web-connected LED” example (LED toggle from the Particle Cloud) in both Web IDE and Particle Workbench.
I did upgrade the Boron LTE via FOTA to Device OS 3.1.0 from the shipping v1.1.0, and also upgraded the Argon via USB to Device OS v3.1.0.
To my surprise, the “Billing & Usage” (Free Sandbox) in the Console showed cellular data usage of 2.40 MB. I thought FOTA cellular does not count towards cellular usage. Also, I wouldn’t have thought that testing out the Web-connected LED toggle a dozen times or so would use 2.4MB of data!
For the last 4 days, both the Boron and the Argon have been offline & disconnected, yet the cellular data usage has increased to 3.03 MB. The data operations are the same as when I last powered up Boron/Argon.
I’ll be monitoring the cellular data usage further as part of my Boron testing to better understand billing & usage.
I’m somewhat confused. Why would cellular data usage change since the Boron was offline for several days?
I’d would appreciate if someone could chime in and offer possible reason(s) for the above.
I have reviewed how the usage charges are calculated but still trying to see the actual numbers vs. what they should be. Thanks!
btw - I’m pretty impressed by the Boron/Argon boards and the online Particle dev resources. Looking forward to getting familiar with Device OS and getting some cellular projects off the ground!
