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

AFAIK the connection interval alone won't be enough to synchronize the two devices, but this tutorial explains how to do just that, with either 2 or more BLE devices.

Best regards,

Simon
