What hardware is available when using Zigbee and Zephyr

I got a reply from the devs today. In Zephyr, the Zigbee stack uses the Timer2 indeed, but not an RTC instance anymore, as it now relies on the Zephyr system ticker while sleeping. It does use the RNG instance I mentioned though, and an UART instance or the USB peripheral if you do CLI/logging over UART or USB.

Best regards,

Simon

Still waiting for confirmation on which peripherals exactly the Zigbee stack is using in NCS, but there's at least one timer, one RTC instance, the RNG, and an UART instance or USB if you di CLI/LOG over UART/USB.

I found that if I try to use timer 2 the Zigbee stack does not use but if I switch my code to use timer 3 it works fine. Thus I assume that the Zigbee stack is making use of timer 2. The question, am I correct and what else is it using, apart from the radio of course.

Unfortunately, due to the summer vacation period here in Norway, we're short on Zigbee experts in tech support at the moment. I did not find any specific peripheral requirement overview for NCS, so I have requested this internally and will get back to you. I'd imagine that the peripheral requirements for Zigbee are the same as in the nRF5 SDK though.
