Hello,

I am pursuing a similar venture with a requirement to use BT and timesync at the same time.

Can I get some confirmation on the above quote? How can I be able to use timesync and bluetooth at the same time - are there samples yet that demonstrate this ability? What libraries would I be able to use in order to employ MPSL and BT at the same time?

Thanks

Yeah, try that. Please get back to me if you're encountering issues.

Thank you for the good news. I have both version of silicon. The NCS should also be updated for using all the channels with the nrfx_dppi API. I will try it by modifying DPPI_CH_NUM in modules/hal/nordic/nrfx/mdk/nrf5340_network_peripherals.h.

On the newst version of the network core, there should be 32 DPPI channels available. As long as you're not using an older silicon, there shoud be 32 available channels. The documentation is wrong and needs to get updated.

Best regards,

Simon

Regarding the question about MPSL and Zephyr LL compatibility, the answer is a clear no. The Zephyr BLE Controller is not compatible with MPSL.

Regarding the other question, the amount of DPPI channels the SoftDevice Controller uses, it should be possible to free up a few. I've asked how to go about this. I'll keep you updated.

Best regards,

Simon
