Reporting interval setting?

[hmorkemo]

Interresting work on the mi flora!
Do you know how to set the reporting interval? Now, mine send sensor data extremely often, sometimes several per minute.
I'd like to set the interval to once every 30 minutes or so, in order to extend battery life.
Have you done any research on that?

I read somewhere that the interval is set in firmware and cannot be changed.
