MPSL timslot sample: sender and receiver

[klaus1234]

Can some one describe how this is supposed to work:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/mpsl/timeslot/README.html

I would have expected to see some sender and receiver code.

Can I run this on 2 different boards? and exchange data?

Hi Klaus,

The MPSL (Multi-Protocol Service Layer) timeslot functionality is different from a typical sender/receiver communication example. The timeslot API allows developers to implement their own 2.4 GHz proprietary protocol that can run concurrently with other protocols using MPSL. It essentially gives your application access to the radio and other restricted peripherals during defined time intervals (timeslots).
I suggest that you refer the timeslot documentation here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/mpsl/doc/timeslot.html 

1. The code snippet you shared with bt_data_cb is from Bluetooth API and not the Timeslot API. These are different mechanisms. When using MPSL timeslots, you need to implement your own radio protocol handling (configure, receive, etc.) within the timeslot callback. 

2. The timeslot will be scheduled at the next available time that doesn't conflict with higher-priority activities. If there's a conflict with a higher-priority event (like critical BLE packets), your request might be canceled. See here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/softdevice_controller/doc/scheduling.html#timeslot_api_timing
