[Here](./code/b-parasite/README.md) you can find a byte-by-byte description of the data as it is encoded inside the advertisement packet. # Battery Life -**tl;dr:** By taking readings 10 minutes apart, the battery should last for over a year. +**tl;dr:** By taking readings 10 minutes apart, the battery should last for over a couple of years. The main parameters involved in estimating the battery life are: * Current consumption (both in operation and during sleep) * Duty cycle (how much time it spends in operation vs. sleeping) -* Battery capacity - this is roughly 230 mAh for CR2032 cells +* Battery capacity - this is roughly 200 mAh for CR2032 cells -In the following screenshot, I measured the voltage of a 10 Ohm series resistor during the on-cycle, for a 8dBm transmitting power (the voltage is negative, so it is upside down): - -
