To the kind attention of Nordic support team,
I'm interested in a ble example (SDK15.2 nRF52840 nRF52832) where peripheral device is waken up from being in deep sleep mode, when receiving a central message.
I mean, from what I'm reading in https://devzone.nordicsemi.com/f/nordic-q-a/10242/who-and-how-wakes-up-cpu-when-ble-notification-is-received it seems that there is
a timing agreement between peripheral and central. I'd like to understand if this timing agreement is the only way, or there is the possibility to awake a peripheral device from a deep sleep
using a complete special asynchronous message coming from central. Obviously peripheral should be able to have antenna listening without too high consumption.
Hope to be clear. Is there an example like this?
From what I know both Peripheral and Central supports bi-directional data transfer. I wanted to well understand by Bluetooth Specifications if,
after a connection has been created, it is possible for peripheral device to go in deep sleep mode waiting a Central message in order to be awaken up.
Should be the case, may ask to Nordic experts to help me find where this is defined in bluetooth specifications? And what example they recommend in order to
implement such a scenario.
Thank you for all your attention,
Best regards
