I have a small network at my home, running on these radios and i have no problems, no packet loss etc. And the sensors are all over the house. Some time ago i also tested these outside and i remember reaching ~30 meters without any packet loss. Also, i don&#39;t remember now actually but i think if you have disabled the auto acknowledge function, you should receive everything what your radio catches. Enable ACK allows you to get ant interrupt and read received data from the radio only then you get a correct packet.</p><div style="clear:both;"></div>
