Is it the host will receive difference &quot;pipe&quot; number?en-USTelligent Community 13Tue, 26 Apr 2016 09:14:01 GMThttps://devzone.nordicsemi.com/thread/51343?ContentTypeID=1Tue, 26 Apr 2016 09:14:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e12dcff0-b3b1-4e4e-9e5e-c187581d4048Kenneth<p>If you have a device that transmit data using an address that is used by several hosts, then you may receive an ACK (+packet) from one random host or you may not receive any ACK due to interference when all hosts transmit the ACK (+packet). The Gazell protocol is not designed to operate with several host using the same address.</p> <p>It is the address that decide if the packet can be received or not. &quot;Pipe&quot; is just a logic name we use to setup several addresses on a host. So it is possible to receive on any pipe if the address fit.</p><div style="clear:both;"></div>
