In order to get a TX_DS you will need a counter-part that ACKs the transmission. This is because ESB is enabled by default, and it handles low-level RF protocol for you. You can read more about the Enhanced ShockBurst protocol in our datasheet.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/13484?ContentTypeID=1Mon, 08 Sep 2014 11:21:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dded65cb-4807-460d-bfd3-1b8ecbf8dcc2Everdoubtful<p>Hi Hakon, thanks for reaction, no, i meant ptx example, i just trying to send few bytes through tx-interrupt.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/13483?ContentTypeID=1Mon, 08 Sep 2014 11:14:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:553372d1-4370-4c99-9770-5c390512a76bH&#229;kon Alseth<p>How is your receiver setup? Are you using the enhanched_shockburst_examples/prx as a counter-part? The PRX must be setup with the same configuration as the PTX for the communication to work properly.</p><div style="clear:both;"></div>
