The interrupts field is already set in the .dtsi file for the SoC, so you do not need to set it in your overlay file.

The field is used by the driver to know which interrupt to use for the peripheral, but it is not something you need to use yourself.

Hi Didrik,

I assume there is no simple answer to my questions above and will evaluate

Thank you.

Best regards,

Hi,

Have you considered moving the BLE host layer to the MSP430, and just running the BLE controller on the nRF52?

That would let you use one of the hci_<transport> samples on the nRF52 without any modifications to the sample.

Depending on the availabel libraries etc. on the MSP430, that might be easier than to emulate the behavior of the nRF8001.

Best regards,

Didrik
