What hardware is available when using Zigbee and Zephyr

[IanAber]

If I am creating an application using the Zigbee stack running with nRF Connect SDK and Zephyr, what hardware is not available to me because it is already consumed by the SDK? In particular, I am looking to use a timer to accurately time an incoming signal on a GPIO line but if I try to set up timer 0 I get an assert indicating that there was a problem with the radio interface. Is there a hardware timer I can use for this? I am trying to set it up with PPI to measure the pulse width.

Is the some reference document that lists all the resources used by the base environment to support the Zigbee stack and Zephyr

Hi

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.

Best regards,

Simon

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.
