DECT NR+ How to access MAC Layer in modem?

Question

Hi, we are currently implementing DECT NR+ mesh network as part of a thesis, where our one part of our plan was to implement full MAC layer (otherwise its just a full mesh network we want to implement and research). We heard that a new sample was out, called "Hello DECT" which is a full stack example in comparison to the MAC demo that was in DECT Shell. We were told that the mac layer was implemented on the modem side, exposed through a stack API (we saw the modem driver for DECT, which had all the methods we need). After looking through the sample and code, we are unsure how to use the "stack API" and access the methods that are within the modem.

Another question is, we wondered if there was any implementation for DLC / convergence layer? We planned to implement it ourselves, just had to make sure since we were confused about one mail stating it was a fullstack sample, so we thought more layers was a part of it as a result.
Sorry if any of the answers are obvious.

Thanks,
Ådne.

Hello, 
 After looking through the sample and code, we are unsure how to use the "stack API" and access the methods that are within the modem. 
 You don't use the "stack API" directly, you access the MAC implementation by using the Zephyr socket API like you would access any other networking interface. If you want to access the MAC layer directly in application, you would need to implement your own on top of the PHY API . 
 Another question is, we wondered if there was any implementation for DLC / convergence layer? 
 I believe you need to implement this yourself, as this part of the stack is internal in the modem.
