However, you should note that not all networks support AS-RAI yet.</p> <p>To use AS-RAI, you must first enable support in the modem, using the <a href="https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/nw_service/rel14feat.html">%REL14FEAT AT command</a>.</p> <p>Then you must enable it with the <a href="https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/nw_service/rai.html">%RAI command</a>.</p> <p>Finally, use the <a href="https://github.com/nrfconnect/sdk-zephyr/blob/main/include/zephyr/net/socket_ncs.h#L58-L80">RAI socket options</a> to actually control when the RAI flag is set.</p> <p>Best regards,</p> <p>Didrik</p><div style="clear:both;"></div>
