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 OBJECTIVE OF THE PROJECT : IMPROVE BATTERY LIFETIME 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.
