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)?

Hi Gil

You can use the Online Power Profiler in order to get some estimates on current consumption for various scenarios. Are both central and peripheral going to be battery-powered, or is the central going to have a reliable power source? Either way, what you're describing seems to consume quite "a lot" of power.

The fact that the peripheral is required to listen for messages at all times has me leaning towards the two devices being connected in order to achieve the highest success rate. I suggest you check out some scenarios using the online power profiler and find out what suits your application best.

Best regards,
