RF noise?</em>&quot; message. I see that the ranging is quite a bit larger just before the disconnect. Could this disconnect be due to the devices being too far away from each other? At what distance between the devices do you see this disconnect exactly? Did it work for a while since you verified the answer before seeing this error again?</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
