https://devzone.nordicsemi.com/f/nordic-q-a/63112/having-trouble-receiving-the-data-on-nrf2401-receiverSo I&#39;ve been tinkering with nrf2401 module lately and trying to send data between the modules. PTX is set up on STM32 and PRX on RPI, and i&#39;m sending from PTX to PRX. I&#39;m using an existing library on RPI , and using receiver.cpp (with minor changesen-USTelligent Community 13Tue, 30 Jun 2020 09:00:27 GMThttps://devzone.nordicsemi.com/thread/257514?ContentTypeID=1Tue, 30 Jun 2020 09:00:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a9e9921f-c8f4-446d-ba24-898be196a1f4Kenneth<p>That should work yes.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/257447?ContentTypeID=1Mon, 29 Jun 2020 16:55:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dd032f20-7e4e-45ed-ab0a-d6d4a885821bmorpho<p>thanks for the response. I want to use no ack to begin with. So if you were to send multiple payloads, would&nbsp;you repeat the following flow for each payload to be sent?&nbsp;</p> <p><pre class="ui-code" data-mode="c_cpp"> void transmit(int *data, int len) { write_payload(data, len); enable_CE(); // ...
