ESB event handler not called in PTX modehttps://devzone.nordicsemi.com/f/nordic-q-a/15504/esb-event-handler-not-called-in-ptx-modeHi, I wrote a program that uses ESB communication between two nodes. On both sides I use the same ESB configuration and the same ESB init function, the difference is only what the nrf_esb_mode is being set to ( NRF_ESB_MODE_PTX or NRF_ESB_MODE_PRXen-USTelligent Community 13Tue, 02 Aug 2016 17:32:53 GMTRE: ESB event handler not called in PTX modehttps://devzone.nordicsemi.com/thread/59213?ContentTypeID=1Tue, 02 Aug 2016 17:32:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f63a4dc-43b3-445b-a8b8-a345d6ecb8c0NewtoM<p>OK, it was a long journey, but I seem to have the answer.</p> <p>To properly change role from PRX to PTX it is not enough to change <code>nrf_esb_mode</code> and call <code>nrf_esb_init()</code> with the changed configuration. It is also necessary to call <code>nrf_esb_stop_rx()</code> prior to that. Then, events will occur and can be handled in PTX mode as expected.</p> <p>Vice versa, when changing from PTX to PRX, aftger the <code>nrf_esb_init()</code> also <code>nrf_esb_start_rx()</code> needs to be called.</p><div style="clear:both;"></div>
