Hey

Sorry for the late response, I am going to implement these changes and see how it works. Might also pick up one of those power profiler kits, looks useful. Thanks!

Hello epice500,

Just some humble thoughts that come to my mind when I am looking at your code (main.c):
- Make sure all pins you do not need are set to open;
- Disable the led(s), because I really doubt somebody is watching after product installation ;-)
- Tweak the BLE advertising settings like interval;
- When you do not need the i2c master set it's pins to open;
- When you do not need sensor interrupts set it's pins to open;
- Try sending less (use buffering) perhase sending buffered chunks consume less power.
- Disable logging (at least in your release build of the software; it drains power.)
- Do not use delay but timers
- Check the error code values and act correctly upon it.
What happen upon APP_ERROR_CHECK it hangs itself. I very doubt this is intended by design for your product?
- Measure the power consumption of your sensor using the Nordic Power profiles Kit 2 (PKK2) a must have tool for every embedded engineer.
