https://devzone.nordicsemi.com/f/nordic-q-a/13136/gazell-dynamic-paringMy application need more than one of the host in the same area, we will set difference pipe of each host, we want to know the area already exist which of the pipe. Then we can prevent to paring with incorrect device. Please advise how can I do?

The actual define is:</p> <pre><code>#define GZP_HOST_RX_POWER_THRESHOLD -64 ///&lt; RSSI threshold for when signal strength in RX packet power is high enough. </code></pre> <p>You can adjust the GZP_HOST_RX_POWER_THRESHOLD to fit your requirements.</p><div style="clear:both;"></div>
