Can one run the Zigbee/ZBOSS-stack and FreeRTOS together?

[Øyvind]

I have a BLE project that I wish to add Zigbee to (non-concurrent, if that matters). The project is built on FreeRTOS with several threads, using SDK 5.2.0 and S140 6.1.1, will migrate to SDK for Zigbee and Thread 2.0.0 if possible.

There are some related details I can't find in the documentation:

• Can zboss_main_loop_iteration(); be called from a preemptible thread, or does it need protection from preemption?
• Are there any timing requirements for zboss_main_loop_iteration();?
• Anything else one needs to be aware of when running ZBOSS in a multithreading environment?

From the devs:

We're currently looking into that.In general it should be possible but I'm sure well face some gotchas. Only some parts of the API are thread safe and we don't yet have a good understanding what is and what isn't possible.

Thanks. For what it's worth, I never need to use the ZBOSS API from more than one context. My concern is mainly whether there are any hard real time requirements or if it can handle being blocked for some milliseconds or more.

Edit: Preliminary, very limited testing does not indicate any problems, but obviously I need to be more sure before I ship :)
