On the STM32WB series? Next time please include the chip number.

If you're doing a few $100M in business, and have a deep bench, a lot of things are possible.

Thanks for your answer. Yes it is STM32WB55. The doubt is I want to write a IEEE 802.15.4 based application for my project. This should be zephyr rtos based. I am not sure whether the 15.4 stack from st is compatible with zephyr
