When you increase the PTW, the sleep period will be shortened, and in this case it seems the sleep period is just below the threshold.</p> <p>See the AT command documentation for more information: <a href="https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/mob_termination_ctrl_status/xmodemsleep_set.html">https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/mob_termination_ctrl_status/xmodemsleep_set.html</a></p> <p>Best regards,</p> <p>Didrik</p><div style="clear:both;"></div>
