- deep sleep power consumption
|wakeup cycle 1.7 sec including RF
see also Low power performance section :
stress test with a full report (2 segmented rf packets) every 3 seconds, battery drop from 3.2 V to 3.01 V so ~ 0.2 V in 49 days
- minimum battery voltage
crash happened at 2.65 V might be due to another issue
Thanks @wassfila for that test. I found this paper about “Coin-cells-and-peak-current-draw”
and based on that added a 100uF cap to one of my Sensortags
Lets see how this will turn out. I have 2 Tags which died within the past few weeks because both are kind of running for the same time now (few month) so the battery is getting low on juice. I can now directly compare if the one has this issue more often then the other.
I think we need to observe from inside rather. Easiest is with led status to see if the loops keeps running, if it’s an os crash or an i2c bus crash.
If it’s an os crash we need serial debug to figure out the crash adress
