BLE working mode configuration

[Gil]

I have a peripheral and central units, both based on nRF52832.

Both of them have to be able to initiate a messege to the other at any time.

Both of them have be able to listen to a messege from the other at any time.

In order to get the most power savings, would it be better to leave a BLE connection at all times between the two? or move back to advertise stage (every say 300msec interval)?

WOW, this tool is perfect. Helps a lot.

Just one question about it. 

I have set the ROLE as "Connection (peripheral)" to check average current and set the "Connection interval (ms)" to 300.

Does it mean that the peripheral and central will both be synhronized to wake up together every 300ms and exchange data (and go back to sleep after data exchange)?

Are they really synchronized to do it together?
