Hi Simon, many thanks for your original answer. I wonder whether you know if Zephyr [atomic variables](https://docs.zephyrproject.org/3.0.0/reference/kernel/other/atomic.html) or the Nordic Atomic Operations API work for variables shared across both the network and application cores in the nrf5340?

Many thanks,

Colin

Thanks Simon, I hadn't realised that. Do you know regarding the behaviour with respect to the C _Atomic type? (https://en.cppreference.com/w/c/language/atomic)

It does not seem like C++ atomics (std::atomic) are supported in NCS/Zephyr at the moment.

Best regards,

Simon
