MPSL synchronization

[GuyYaniv]

Hello,

This is a theoretical question rather than a problem:

Let's say I have 2 devices that need to communicate over standard BLE profile and every so often needs to send raw radio packet (RRP).

For BLE the Rx<->Tx are synchronized via BLE's connection interval.

But if I use MPSL to facilitate the RRP, how does MPSL synchronize that both device get their time slice to use the radio at the same time (or else there wouldn't be a possibility to communicate)?

Does the MPSL library takes care of timing so both devices get radio access (MPSL_TIMESLOT_SIGNAL_START) simultaneously?

Thanks,

Guy.

Hi,

No. The device clocks drift apart, and so do the timeslots. It's up to the user to decide how to implement their custom radio protocol.
