Forum Post: RE: coin cell battery power management problems

Chatto,

Thanks for your response.  I am working on a project built around the simpleBLEPeripheral sample application, which has the "POWER_SAVING" feature enabled.  This feature seems to be putting the MCU to sleep in between radio events (connection intervals).  My device appears to be going to sleep in between these connection intervals.  The connection intervals are happening once every 100 mSec.  I need them to happen this fast for responsiveness between my peripheral and central devices when they are actively interacting.  When the devices are not actively interacting I want to conserve as much power as possible so that I can preserve my coin cell battery for as long as possible.  In this case would it be better to terminate my connection and then reconnect when the device is being used again?  Or should I renegotiate my connection interval between my two devices so that is happens less frequently like once every 1Sec or longer?  What is the recommended method?

It's the pulsing load on the battery from these connection intervals that is breaking down my battery and increasing my average current draw.  My thinking is that if i terminate my connection when the device is inactive that load goes away, or if I put a longer delay between each interval the average load will decrease significantly.  Either way hopefully I get more out of my battery.

Thanks...
