MPSL ESB+BLE on nrf54L

[Michal]

Hi,

I want to port an exisiting solution from ESP32 + nrf24 to nrf54L15. I didn't find any example that would work out of the box for my POC which would to combine very simple peripheral device with ESB ptx. Is there something like this for nrf54? I found this one https://github.com/too1/ncs-esb-ble-mpsl-demo/tree/master/common but it is based on ncs 2.6.0, while I read that I need at least 2.9.1 to use nrf54l for production, correct?

Best regards,
Michal

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.

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
