Maturity

Release is considered mature, and will be shipped with new RuuviTags.

Ruuvi firmware consumes approximately 23 uA / lasts theoretically for 4 years in RAW mode. URL mode consumes approximately 40 uA and battery should last for 2 years. Power consumption has been verified with Nordic Power Profiler kit on 1.3.3.

Eddystone FW consumes 28 uA at boot and theoretically lasts for 3 years at default settings.
