Hello Guys,

I'm working on a kind of "fitbit" composed of several sensors : temperature, GPS location and accelerometer.

The fitbit send information continuously to a receptor through Lorawan

Currently, I'm facing an important issue with battery lifetime. I would like at least 3 months lifetime and so far I don't get 1 week.

I'm looking for help to IMPROVE BATTERY LIFETIME :

- Development/programming side : Optimize the code and manage the messages between the fitbit and the receiver

- Electronic side : manage and optimize to the maximum the battery and its lifetime !

For information :

-Language : C++

-Microcontroler :

- For the prototype : adafruit feather MO

- Target one : atmel cortex m0 with arduino bootloader


I need a engineer extremely serious and highly qualified.

I would like the code to be as simple and robust as possible, easy to understand and easy to adjust the variables.
