Michal,

There are no limitations coming from from our SoC to run BLE+ESB with MPSL. Make sure that you obey the timeslots rule of closing the timeslot in time before it ends for the BLE to behave correctly.

Hi Susheel,

Thank you for the response. I would like to confirm that there are no known limitations to use BLE + ESB simultaneously on nrf54L15?

Can you also comment what kind of a delay at maximum should I expect when accessing ESB? I plan to set very long connection interval and advertising interval as BLE is not criticial at all, ESB however needs to be access for time critical operations. Is there a way to eg skip BLE event if I need to access ESB ?

Thanks

Hi Michal,

We have a built-in ESB PTX sample at samples/esb/esb_ptx that you can use as your starting point for esb and unfortunately you need to add BLE to it yourself.

If you need BLE + ESB simultaneously, you need MPSL timeslot which you can study from the MPSL sample.
